NEMA23 High Torque DC Servo Motor 600RPM With UART/12C/PPM Drive

Product Code:
£69.19 £57.66

This Encoder DC Servo motor solution integrates an 0.2deg resolution optical encoder and a high power electronic servo drive on an Industrial grade high torque DC motor.

High Torque DC Servo Motor 600RPM With UART/12C/PPM Drive front
High Torque DC Servo Motor 600RPM With UART/12C/PPM Drive front

It supports STEP/PULSE and DIRECTION digital inputs that are opto-isolated. This solution works extremely well for slow speeds by providing high correction torque through a closed PI control loop.

The Motor is a Industrial grade 300RPM high torque motor with a massive torque of 30kgcm in small size. The motor has a metal gearbox with all high quality metal gears and has a off-centered shaft.
