Intelligence in Motion from the worldwide network
Oct 21.10.2023, XNUMX | Koco Motion presents at SPS from November 14th to 16th, 2023 in Nuremberg his expertise for tailor-made drive solutions, including based on servo motors from the Kannmotion platform. On this basis, the system house serves the growing demand for customer-specific drives.
Better reference runs and delivery reliability
16.11.2022 | The Kannmotion servo motor platform from Adlos and Koco Motion has undergone further development: on the one hand, new customer-specific functions have led to an optimization of the overall system. And market acceptance is also increasing. Because if seven original individual units like Motor, Transmission, Encoder, steering, start button, Sensor and cabling found in an overall system, this can only be advantageous in terms of purchasing, supply chain, maintenance and much more. bring.
The cooperation partners constantly check, update and develop the servo motor platform including firmware. Because the drive system accommodates several units in one, the partners make the currently difficult situation on the procurement market easier for their customers. "With our can Motion We were able to guarantee a very high level of delivery reliability,” says Olaf Kämmerling, Managing Director of Koco Motion GmbH. To this end, we have increased the inventory early enough so that even longer replacement times do not pose a risk to our on-time deliveries".
Customer wishes and requirements make every Kannmotion project unique. “Sometimes a customer requirement even entails an improvement in the overall system. We then transfer such adjustments to series production or the resulting firmware,” says Thomas Vogt, managing director of adlos AG. “At the moment, the development steps are more hidden and not directly visible. They hide in reaction times, latency times and regulations. But if, for example, a more optimal reference run leads to a better result, then we make these processes available to all customers," says Mr. Vogt. Incidentally, an update to such new functionalities is very easy and can be carried out intuitively via the Kannmotion Manager.
Servo motor system now also with DC motor
07.12.2021 | Adlos and Koco Motion are now presenting their jointly developed servo motor platform Kannmotion for DC motors. Previously, the servo motor system was only for Stepper Motors offered. The fully programmable, integrated closed-loop drive, which consists of a DC motor with an integrated encoder and a directly attached controller, is just as easy to set up as the combination with stepper motor.
Developed reliable even in continuous operation like a servo motor and can be fully programmed using commands or sequential programs. The digital inputs and outputs already on board as well as an analog input can be fully integrated into the program sequences. The DC motor module is suitable for applications with high dynamics without gears or for powerful and compact use with gears.
The size of the Kannmotion control is 42 x 42 mm for a power range of 45 V and up to 2 A motor current - with optimal cooling up to 4 A. It will be the same Software used as with the stepper motors, so that the user does not have to change here.

Kannmotion servomotors generation 2.0
10.02.2020/XNUMX/XNUMX | Inexpensive and tailored to the application, that is the concept of the Kannmotion platform from Koco Motion and Adlos. Three years ago, the two companies joined forces to create a custom Stepper motor drive system to develop that has never existed before. The stepper motors are completed with additional components, everything that the user needs.

“This adjustment creates added value for our customers by which they can do theirs TCO (total cost of ownership),” says Thomas Vogt, Managing Director of Adlos AG, Liechtenstein. "With our Kannmotion, you only get the precise features you need for your application," adds Olaf Kämming, Managing Director of Koco Motion GmbH, Dauchingen.
Stepper motor with control - structure and function
The drive, which consists of a stepper motor with an integrated encoder and direct control, is available as closed loop designed. The closed-loop servomotors are simple and fully programmable. The customer-specific adaptations of hardware and software are usually based on 80% standard modules, which are put together according to the modular principle.
The compact one drive system also works reliably as a run-in Servomotor and can be programmed using commands or sequence programs of the stepper motor control. It is in the Nema design with the flange sizes Does not have 11, 14, 17, 23, 24 and Nema 34 (e.g. Nema 34, 86 mm x 86 mm) with a holding torque of 0,05 Nm to a holding torque of 12 Nm. The supply voltage is from 12 V to 48 V and the phase current can be up to a maximum of 10 A. The servomotors are used wherever positioning tasks, controlled continuous operation or a programmed sequence of movements are required.
BLDC motor for smooth running and long runtime
The Kannmotion needed fewer components than comparable servomotors. By reducing the number of components, the assembly effort is reduced. Wear and the resulting potential for errors are also reduced. Wear is also reduced thanks to the direct drive of the Kannmotion. By eliminating the gearbox, the noise level is also lower.
The Efficiency is 30 to 50% higher than with a conventional DC gear motor. The stepper motors with controller and Encoder are also very compact because the stepper motor controller is also very compact and sits directly on the drive and the encoder is already integrated. The torque output can be adjusted by adjusting the current. There is anti-trap protection in accordance with the Machinery Directive so that there is no risk of injury when closing a flap.
A technical defect in the event of manipulation or incorrect operation of the drive is also excluded. "If, for example, children were playing around with a drive flap by constantly opening and opening the flap, the transmission would be destroyed," says Thomas Vogt an example. With its elimination, however, the problem is not even present. The servo drive can simply be turned back. The cogging torque from the motor is very low and components are not stressed.
Design of a stepper motor system
How do you have to imagine it if you want to order or design such a Kannmotion system, consisting of a stepper motor with integrated Kannmotion control and encoder from Koco Motion? “Integrating a motor into a new product seems quite simple at first glance: the motor should perform a specific rotary or linear movement. This generated movement is the heart of the servo drive. At this point, our know-how comes into play: the selection of the right drive with the optimally suitable control electronics Olaf Kämmerling the procedure.
To specify the requirements, customers first have to answer many W questions, such as:
- What Speed is required?
- When should the engine turn?
- What engine technology is desired?
- How should the drive attached be?
- which torque or what force?
- What Adaptation to the motor shaft?
- Which one space is aviable?
- How will the drive driven?
- What Lifespan is being expected?
- What Environmental conditions prevail?
Precision gear for input speed with 8500 revolutions per minute
By adapting the stepper motors, efficiency, service life, heating, etc. can be positively influenced. It is important to exchange information at an early stage and to create a realistic schedule. This is followed by the selection of the motor, which may have to be adapted. The motor technology specifies the control. That is what it is aimed at Motion profile described and initiated. Additional functions or components such as display or control elements or peripheral devices are then added like modules.
Stepper motors with control in Industry 4.0
The servo motor can also do Industry 4.0 Communication designed in the smart factory. He has CANopen and RS232- And RS485Interfaces. In addition, the stepper motors can be controlled with digital input and output functions (DIO). Further interfaces can be implemented upon customer request.
“Unfortunately, we cannot describe many specific use cases at this point. Our customers are their own. We have signed non-disclosure agreements with most of them. But I can say this much: From the format adjustment, about Vacuum gripper, vegetable peelers, blood pumps and welding robots, and even musical instruments, the variety of applications is so great that we couldn’t even list them all,” says Thomas Vogt. “But we do have two good examples that show just how much Total Cost of Ownership you can save ”.
“The bottom line is always what you want to pay for direct cutting a drive to the functions that are intended for it. Not only the number of components or their prices play a role here, but also the assembly, maintenance or repair costs - TCO, ”says Olaf Kämmerling yourself and not on the total cost. A rethink here would be very desirable. "
Kannmotion 2.0 and the future
The motor with Generation 2.0 controls has been on the market for six months. improvements were in mechanics, Electronics as well as software. A completely revised tool of the Kannmotion Manager supports the user with the integration.
"Surely the biggest change is the type of Coding. The aim was to have the widest possible range of firmware (software) and faster response times. Now we have created a development environment with which the user can implement his application in the object-oriented flow chart editor or in C code. The sky is the limit, ”enthuses Thomas Vogt.
“Our Kannmotion system has been very well received by the market. Here we have already been able to use various applications in all project stages from evaluation to final testing to series production implement. From our point of view, the possibility of customer-specific execution is still unique, ”adds Olaf Kämmerling.
Adlos and Koco Motion always get new inputs from their customers for a further development of their stepper motor platform. Most recently, they implemented the controller in relation to Nema 11 based on a special customer request. Very close to the customer, they want to drive the development of this unique platform forward in the future. They offer the market products that do exactly what they are supposed to do - no more and no less.
Countless applications from just one platform
16.11.2022 | The components of a Kannmotion servo motor can be put together individually according to the modular principle. The intuitive programming of processes makes the drive particularly predestined for decentralized isolated solutions without complex higher-level controls. The concept is particularly suitable for cost-effective, individual solutions from small series.
Other applications are positioning, controlled continuous runs or programmed movement sequences. With the DC motor, you can do it yourself automate the simplest applications. They often consist of only one axis. The drive receives a signal for further processing based on various circumstances. A permanently stored program that is executed is also an option, as is a position dependent on the voltage applied to the analog input. Examples are control valves, control valves or the drive of an axis with different speeds. With the evaluation of the analog voltage at the input, among other things, a speed dependent on the applied voltage can also vary. This allows the position and speed to be controlled.
A particularly interesting application is the Exchange of pneumatic solutions through miniaturized, electric drives. The power supply here is often 24 V, which can be processed via the inputs and outputs. This makes the conversion inexpensive and very easy. The applications can often be used without major changes in the existing infrastructure. Even if the performance of a miniaturized electric drive is often lower than that of its pneumatic drive, it is still sufficient for many applications. The stroke length is infinitely adjustable and can be easily adjusted via the interface or program.
The variant with a DC motor, which was only introduced this year, was immediately popular, as the following example shows: “For a Format adjustment a brushed direct current motor was equipped with the Kannmotion control. A variant without a gear ensures fast movement with low torque. With another variant with a 36:1 gearbox, we have implemented the necessary torque at the optimum speed," says Olaf Kämmerling, describing the application. Thanks to good control and encoder, the format adjustment can be positioned relatively easily. The overall costs of the drive remained well below the customer's expectations.
Automated Baked Goods Vending Stand
The example of an automated Bakery counter illustrates the savings potential of the servo motor. In order to guarantee the necessary hygiene, the user offers his range of bread behind glass.
The bread in the transparent sales stand is sold via a glass door accessible to the customer. To do this, he must activate the opening mechanism by gently pressing on the door. As soon as this happens, a pre-programmed sequence program starts. The pressure on the door is recognized by the Kannmotion control through the integrated absolute encoder. The sequence program starts when the position change detected on the encoder due to the movement of the door. This will gently open the door. After the programmed time in seconds has elapsed, the door closes again.
If it cannot return to its end position due to an obstacle, the encoder sends a signal to the controller, which sends the door back to the open position. After a defined time, the closing process starts from the beginning. That sequence program is only controlled by the can motion. A higher-level controller is not required.
"The original solution of the drive included seven components: motor, gearbox, encoder, controller, start button, sensor and wiring. These not only caused costs for conception, development, purchasing, maintenance and support, but also represented potential sources of error," points out Mr. Vogt. The various suppliers for the components also had to be selected, which further increased the effort involved in realizing the drive.
With the Kannmotion construction, the Maintenance effort reduced and the system is more reliable. The cabling that is not required is no longer a source of error. "With an application like this, of course, the development costs only occur once, and these are reduced to the required functions," says Thomas Vogt.
Servo motor controls coin sorter without PLC
10.12.2018 | The drive platform "Kannmotion" from Koco Motion and Adlos extended by some features. The cooperation partners recently demonstrated what is possible with this using a coin sorter at the SPS IPC Drives 2018 in Nuremberg. The servo system Kannmotion is a platform for customer-specific applications based on integrated stepper motor controls.
One concept offers many possibilities for the most diverse requirements. The space-saving and cost-optimized drive system is individually adapted to this platform. And that is often worthwhile even for relatively small quantities of 100 or more. The engine can use the free Stepper Config Tools be programmed. With this easy-to-use tool, even complex processes and control algorithms can be mapped efficiently within a very short time. Kannmotion thus opens up new fields of application that have often been reserved for other technologies up to now:
For example, the controls were equipped with a Linear actuator combined and could such a Pneumatic cylinder substitute. The stroke lengths are infinitely flexible. A different speed can be realized within a movement.
These vacuum grippers handle everything
For industrial applications, the Plug be replaced by robust screw connections. If desired, the protection class can even be increased IP65 raise. For networking within complex devices, the servo system now has a CANopen interface in addition to the standard RS232 interface. An IO-Link interface is also planned for 2019.
Complex application with three drives
At the SPS IPC Drives, Koco Motion and Adlos presented the servo system in the application of a coin sorter and thus a complex application without PLC demonstrated. In this coin sorter, coins are separated, their diameter measured, positioned accordingly and finally fed into the correct compartment.
The coin sorter was built with three Kannmotion drives, which are controlled via a DIO (digital input and output) sequence control. Each servomotor has to fulfill a special task. Of the release motor (1) serves as a barrier and lets the coin fall into the compartment provided. Of the vibration motor (2) conveys the coins down the chute by intentionally slipping the motor out of step, causing it to vibrate. If a coin falls into the slide, this one breaks through Photocell and gives the vibration motor the stop signal. The KannMOTION then gives a start signal to the turntable motor (3) further. After receiving this signal, the turntable motor reads the analogue input. A table is stored in the programming of the Kannmotion, which assigns the diameter of the coin to a compartment in the turntable. The turntable rotates into position and gives the start signal to the release motor.
This application is very easy adapt in many ways for example in a rotary transfer assembly machine or on a paternoster. The coin sorter is intended to show how easy and, above all, how flexible Kannmotion can be used.
Vacuum grippers for pressureless handling tasks

Kannmotion servomotors generation 1.0
03.02.2017 | In 2016, Koco Motion received an inquiry from a Swiss manufacturer of analytical equipment who was looking for a drive solution for a major project. The one built into it Valve control for analyzers brought together the companies Adlos, as a controller developer, and Koco Motion, as a drive specialist.
In order to meet the requirements, both companies developed one that was tailored to the application Stepper Motor Control System. The cooperation went so well, quickly and successfully that Koco Motion managing director Gerhard Kocherscheidt and Adlos managing director Thomas Vogt then signed a long-term cooperation agreement.
“We want this Multiply the concept of successbecause existing products from our delivery program or those available on the market do not optimally meet such requirements, ”says Gerhard Kocherscheidt. Thomas Vogt adds: “To implement this goal, we will modify existing hardware and adapt the software precisely to the needs of the customer. We estimate the development effort required to be between 10 and 20 percent depending on the application ”.
Presentation of the Kann Motion platform for market launch
02.02.2017 | Gerhard Kocherscheidt, managing director and company founder, Koco Motion GmbH, Dauchingen and Thomas Vogt presented 2017 in one Lecture presented the new "Kannmotion" servo motor on the occasion of the specialist press days of the RBS Stutensee in Karlsruhe.
The koco Motion the develops and manufactures small DC motors and gears as well as special motors in Dauchingen, Baden. In addition, the eighteen-strong operation is the exclusive sales partner of the American company SEM (formerly Intelligent Motion Systems) and of Constar and Dings – Chinese drive specialists for stepper motors, linear actuators and DC motors.
BLDC motor: when the DC motor reaches its limits
The Adlos AG from Liechtenstein is an independent provider of engineering, electronic assemblies and production services. The group includes three companies with around 200 employees in over 50 countries. The engineers support companies in consulting, project management, analysis, design, construction, implementation as well as testing and production.
Stepper motor, encoder and control
Simple. Cost-optimized. Customer-specific: This is the objective of the cooperation, which relates to a new drive platform to be created. Under the working title can Motion Based on the customer-specific development mentioned above, a new servomotor system was created, consisting of a stepper motor with an integrated encoder and a direct control.
"Our Kannmotion system gives our customers competitive advantages that are generated by the customer-specific design", describes Thomas Vogt the unique selling point of the new development. “And it can only do what it needs to be able to do - and that perfectly,” says happily Gerhard Kocherscheidt And further: "The system is qualitatively and functionally comparable to the drives currently offered in Europe, but also offers a significant cost advantage, achieved through the components built into it - which are necessary and tailored to the application." The systems will be completed in Europe.
Concept of new development
First of all, the cooperation partners have a Cost use Bill carried out in projects that have already been successfully completed and are currently running. On the mechanical side, for example, a stepper motor is used instead of a DC motor with a gearbox. This results in a saving in components, along with less wear, longer service life and less noise. Or it will Pneumatics replaced by a stepper motor with electronic control. The closed-loop control takes over the speed control of the motor as well as the torque control and the positioning.
DC motor as an all-round talent for countless applications
Compared to pneumatic control systems, Kannmotion any driving profile like controlled starting and Brakes, the assumption of intermediate positions, more functionality, longer service life and lower noise development can be achieved with lower operating and service costs.
Reliable function and easy programming
The compact Kannmotion works reliably like a servo motor and can be Program using commands or sequence programs. Its areas of application can be found wherever positioning tasks, controlled continuous operation or programmed movement sequences are required. In addition, the digital and analog inputs and outputs on board can be programmed to initiate the movement sequences. The Kannmotion is available in flange sizes Nema 17, 23 and 24 with a torque of 0,4 to 3,0 Nm. The supply voltage is 24 V to 48 V depending on the application.
Communication takes place via the RS232 interface as standard. The motor parameters are each stored in the internal memory. Additional parameters and commands for desired motion sequences can be sent to the motor control via an easy-to-use terminal program. Operation is simple: All commands can be selected from a drop-down menu. The description of each command is displayed on the right side of the screen. The servo motor can also be easily programmed using the ASCII code. The captivating simplicity of the terminal program enables the user to turn motion sequences into reality in the shortest possible time.
Application examples with value analysis
“Due to its flexibility, the Kannmotion concept is suitable for a large number of applications in very different areas such as for broad industrial use and we even have one Musical instruments-manufacturer, who now adjusts a vibraphone with our servo motor," says Gerhard Kocherscheidt, describing the market launch so far.
In a Rotary heat exchanger A price reduction of 65 percent could be achieved by saving the gearbox and the associated minimization of wearing parts. With this development, the noise level has decreased by 30 percent.
Connectivity for the future comes from Harting
When using the Kannmotion in one Pick and place machines does this now come without SPS and switch cabinet out, which reduces the sources of error and wear. An integrated IO control simplifies the wiring. Instead of 230 VAC, the construction uses 24 VDC and thus complies with the Machinery Directive.
“The bottom line is that the platform is as ideal as necessary, because by combining standard and customer-specific adaptations, we can generate values that generate unique selling points. The absolute creed are them Total Cost of Ownership (TCO) ”, is how the engineering service provider sums up the benefit.
Medium-sized competence center
With the cooperation, the two companies have created a strong competence center for Kannmotion, in which almost all customer requirements can be implemented thanks to the medium-sized flexibility. The engineers are currently working on the implementation further interfaces like CANopen and the rest.
"Incidentally, we are open to all industries and invite our customers to work closely together on new developments," the drive specialist promises. Since for the optimization of a drive or a control system there is always development work and possibly also Tools are required, which cause initialization costs, a minimum of 100 systems is required to implement a customer-specific system. Previous projects include Numbers from 1000 to 10.000.
"We are pure idealists here", Thomas Vogt admits to further objectives. “With our customer-specific Kannmotion servomotors, we are unbeatable in terms of quality and price Drive solutions for mass production realize. "And should it be about smaller quantities - no problem:" We still have our extensive standard portfolio for that. Because with a quantity of 1 and small series, these drives are simply more economical, ”concludes Gerhard Kocherscheidt.
General technical knowledge
What is a stepper motor?
A stepper motor is a synchronous motor. In its stationary stator with coils, a rotor rotates through a step-by-step (step angle) rotating electromagnetic field. The torque for driving the rotor is created by the differently oriented magnetic fields in the rotor and stator. The rotor can be rotated by a small step angle or by a multiple. Stepper motors are also available in this version Linear motor.
What is a servo motor?
A servo motor is an electric motor with a sensor or encoder that allows feedback and controllability of the position of its motor shaft linear or rotary, the rotational speed and the acceleration. The so-called servo controllers are used to regulate the speed of the servo motors, regulate the current and regulate the position. A servo motor is based on different motor types such as stepper motors, DC motors, synchronous motors or asynchronous motors.
