The SM23405D is a NEMA 23 size SmartMotor™ is an entire servo control system built inside of a servo motor. This motor includes an integrated motor, controller, amplifier, encoder and communications bus. SmartMotors™ are true servo motors, which eliminates issues like error accumulation and missing steps found in traditional stepper motors.
