NEMA23 High Torque DC Servo Motor 900RPM With UART/12C/PPM Drive
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.
It supports UART/I2C/PPM/Analog signals directly for absolute speed and absolute position control. 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 600RPM high torque motor with a massive torque of 18kgcm in small size. The motor has a metal gearbox with all high quality metal gears and has a off-centered shaft.
