NEMA 17 closed-loop integrated stepper motor

29 April 2018

JVL Industri Elektronik A/S has introduced a new compact and slim stepper motor.

The ServoStep integrated stepper motor series MIS171 to MIS176 features a NEMA 17 42 x 42mm flange and includes a controller with six industrial Ethernet protocols, absolute multiturn encoder, closed-loop and M12 connectors.

The new motor family is based on the latest microprocessor and cooling technology and an advancement compared to previous designs.   

All the necessary electronics in a stepper system are integrated in the motor itself and are similar to the concept used in the company’s other servo motors. The motor contains everything needed to solve a modern control task – either as a stand-alone easily programmable motion controller or controlled from an external PLC or PC. Eight I/O points can be individually configured as digital input, digital output or analogue input. Modbus RTU or CANopen provide connections to a PLC or HMI.

An ActiveX/OCX driver is available to make a simple interface to LabView, Excel, VB or other Windows-programs. Up to 254 axis can be connected on the same RS485 bus.

The stepper motor can achieve step resolutions of 409,600 step/revolution, resulting in smooth and silent running. It can also provide speed-precision 0.01 RPM and acceleration precision 1 RPM/sec.  

?A newly developed heat transfer system, power electronics and special motor windings offer high efficiency with peak powers of up to 100 W and 1 Nm.
