Stepper motors with integrated multiturn absolute encoder

22.10.2018/XNUMX/XNUMX | Koco Motion offers the Lexium mdrive (LMD) stepper motors from Schneider Electric now with a multi-turn absolute encoder. This expands the performance of the integrated stepper motors - and with the same dimensions.

The multiturn absolute value encoder function with a number of lines of 1000 was added to the All in one engine integrated. This gives users a fully-fledged servo system based on the advantages of a stepper motor positioning drive with absolute displacement measurement. This enables new application possibilities in the most modern machines and systems. The well-known IP protection classes up to IP67 allow use in harsh environments. The rotary and linear stepper motors are available immediately.

The LMD with integrated multiturn absolute value encoder follows the trend of integrating more and more components into individual units and thus making the drives smart. This improves operations while reducing costs. Because the absolute encoders replace sensors or limit switches. LMD drives with absolute Encoders record and save position data even when switched off. This eliminates the necessary reference runs after switching off the controller. The system is immediately ready for use, the set-up time when starting the system is reduced.

BLDC motor for smooth running and long runtime

The LMD stepper motors with absolute encoders have a fully programmable motion control. They can be operated in different modes: closed loop, torque control and variable current control for energy savings and reduced heating. The communication protocols Ethernet/IP, Profinet, Modbus TCP, CAN open and RS-422/485 are available for network capability.

Hollow shaft for the stepper motor supply lines

27.11.2017/XNUMX/XNUMX | There is now one for Koco Motion's stepper motors hollow shaft version. This makes many new applications possible that require the passage of supply lines. Until now, stepper motors have only been available with solid shafts in all flange sizes from 20 x 20 mm to 86 x 86 mm.

All these sizes are now available with through holes from 3 to 16 mm available. These motors are therefore particularly suitable for applications in which, for example, light in optical applications or compressed air for grippers as well as the electrical supply for lighting or aggregates have to be supplied.

Stepper motor technology offers high step resolution and high holding torque. The full step angle of 1,8 degrees, paired with a micro step control, enables precise and high-resolution positioning and excellent smooth running. The hollow shaft stepper motors are also available with an encoder for precise position monitoring and with the option of Closed loop control.

FAQ

What does nema mean?

NEMA stands for "National Electrical Manufacturers Association", a renowned standards organization in the United States, which develops standards and guidelines for electrical devices and components. In the context of stepper motors (ICS 16-2001 standard “Motion/Position Control Motors, Controls and Feedback Devices”), NEMA refers to the standardized dimensions of the motor housing and mountings. Here is some important information about the NEMA standard:

Frame Size: A stepper motor's NEMA number indicates its frame size, with a higher number indicating a larger size.
Simplified integration: The standardized sizes make it easier to replace and integrate stepper motors into existing systems.
No Power Information: It is important to note that the NEMA classification does not provide any information about the power or torque of the motor, it only defines its physical dimensions

An example of the different Nema sizes for stepper motors: Nema 23 means 2,3" (inch). This corresponds to 58,42 mm and is rounded off to the flange size of 56,4 mm.

What is a stepper motor simply explained?

are stepper motors electrical Engines, which are often used in industry for precise and reliable positioning tasks in the Drive Technology such as the motion control application. The motor is controlled by electrical pulses, each pulse moving the motor forward one step. Unlike traditional engines, turns one stepper motor not continuously, but as the name suggests: step by step.

BLDC motor: when the DC motor reaches its limits

The structure and the way it works A stepper motor consists of several coils in the stator, which are wound around a rotor. These generate a magnetic field and move the rotor with permanent magnets or electromagnets in discrete steps. The step angle or the number of steps that determine the positioning accuracy depend on the design and number of magnets. The rotary movement is controlled by means of transistors, which regulate the flow of current in the windings. Simply put, a stepper motor is a type of precise, controllable motor that performs motion in discrete steps.

There are different Types of stepper motors, such as synchronous motors and hybrid stepper motors for various applications and performance requirements. Stepper motors are a cost effective solution for precise Positioningtasks and are used in numerous industries, such as Automation, Medical Technology, Robotic and Product development, used.
