Stepper motor with controlHannover Messe Hall 5, Stand A31

cover story

koco Motion and Adlos have their ingenious unique platform "can Motion"revised. The cooperation partners present the one Stepper motor with integrated control and encoder existing drive generation 2.0, Electronic and mechanical improvements were made and the software further developed. The operating tool for the stepper motors has also been completely revised. It now supports users even better in integrating the platform into their product development.

Inexpensive and tailored to the application, that is the concept of Can Motion Platform by Koco Motion and Adlos. Three years ago, the two companies joined forces to develop a customer-specific stepper motor drive system that had never existed before. The stepper motors are completed with other components, just everything the user needs.

"This adjustment creates added value for our customers, through which they can optimize their TCO (Total Cost of Ownership)," says Thomas Vogt, Managing Director of Adlos AG, Liechtenstein. "With our Kannmotion you get exactly the features you need for your application," adds Olaf Kämmerling, Managing Director of Koco Motion GmbH, Dauchingen.

Stepper motor with integrated control and encoder

stepper motor with controllerThe drive, consisting of a stepper motor with an integrated encoder and direct control, is designed as a closed control loop. The closed-loop drive is simple and fully programmable. The customer-specific adaptations of hardware and software are usually based on 80% standard components, which are put together according to the modular principle.

The compact drive system works reliably like a servo motor even during continuous operation and can be programmed using commands or sequence programs of the stepper motor control. It is available in flange sizes Nema 11, 14, 17, 23, 24 and Nema 34 (e.g. Nema 34, 86 mm x 86 mm) with a holding torque of 0,05 to 12 Nm. The supply voltage is from 12 V to 48 V and the phase current can be up to 10 A. The motors are used wherever positioning tasks, controlled continuous operation or a programmed motion sequence are required.

Few components have advantages

Stepper motor with controllerThe Kannmotion requires fewer components than comparable motors. The assembly effort is reduced by reducing the number of components. 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 geared motor. The stepper motors with control and encoder are also very compact because the very compact stepper motor control is located directly on the drive and the encoder is already integrated.

The torque output can be adjusted by adjusting the current. There is a pinch 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 gearbox would be destroyed", Thomas Vogt describes an example. By eliminating it, the problem was not even present. The drive can simply be turned back. The cogging torque from the motor is very low and components are not loaded.

Design of a stepper motor system with an on-the-spot guarantee

Stepper motor with control and encoderHow do you imagine it now if you want to order or design such a Kannmotion system consisting of a stepper motor with controller and encoder from Koco Motion? “The integration of a motor into a new product appears very simple at first: The motor should perform a specific rotary or linear movement. This generated movement is the heart of the drive. This is where our know-how comes in: selecting the right drive with the optimally matched control electronics, ”is how Mr. Kämmerling describes the procedure. To specify the requirements, customers first have to answer many W questions, such as:

  • What speed is needed?
  • When should the engine turn?
  • Which engine technology is desired?
  • How should the drive be attached?
  • What torque or force?
  • What adaptation to the motor shaft?
  • What space is available?
  • How is the drive controlled?
  • What is the lifespan?
  • What are the environmental conditions?

By adjusting the stepper motors, efficiency, service life, heating, etc. can be positively influenced. It is important to exchange information early and to create a realistic schedule. Then the motor is selected, which may need to be adjusted. The motor technology specifies the control. The movement profile is described and initiated accordingly. 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

Olaf KämmerlingThe stepper motor with control and encoder can also be Industry 4.0. For this, its makers have designed the Kannmotion for communication in the smart factory. It has CAN open as well as RS232 and RS485 interfaces. The drives can also be controlled with a digital input and output function (DIO). Other interfaces can be implemented on customer request.

"Unfortunately, we cannot describe many specific applications here. Our customers are special there. We have a nondisclosure agreement with most of them. But I can say so much: From the format adjustment, to vacuum grippers, vegetable peelers, blood pumps and welding robots, even musical instruments, the range of applications is so great that we couldn't list them all anyway, ”says Thomas Vogt. "But we have two nice examples that show how much total cost of ownership can be saved."

“The bottom line is always what you want to pay for the direct tailoring of a drive to the functions that it is designed for. 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 Generation 2.0 and the future

Thomas VogtThe stepper motor with generation 2.0 control has been on the market for six months. Improvements have been made in mechanics, electronics and software. A completely revised tool from the Kannmotion Manager supports the user during the integration.

“The biggest change is certainly the way of programming. 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.

“The market has received our Kannmotion system very well. We have already been able to implement various applications in all project stages, from evaluation to final testing to series production. In our view, the possibility of a customer-specific version is still unique, ”adds Olaf Kämmerling.

Adlos and Koco Motion always receive new inputs from their customers for the further development of their stepper motor platform. Most recently, they implemented the control in relation to Nema 11 based on a special customer request. They want to continue driving the development of this unique platform very close to the customer. In doing so, they offer the market products that do exactly what they should - no more and no less.
