Stepper motor with encoder is a stepper motor integrated with encoder, it is designed to realize closed-loop feedback control, it can avoid the loss caused by step loss of stepper motor. Encoders from STEPPERONLINE can be divided into rotary encoder and optical encoder. Our customers can choose the suitable one according to their requirements. Generally, the rotary encoders loaded to connect with a shaft that emits pulses with proportion to the rotation of the shaft which can be used to measure rotating speed and with the help of PWM technology, it can control speed in a very short time.

The main difference between the stepper motor with encoder and the closed-loop stepper motor is the receiving mode of encoder signal. The encoder signal of the encoder stepper motor is accepted by the control system, and the encoder signal of the closed-loop stepper motor is accepted by the stepper motor driver.
