Servo motor encoder is installed on the servo motor is used to measure the pole position and servo motor Angle and speed of a sensor, from the different physical media, servo motor encoder can be divided into photoelectric and photoelectric encoder.
The brushless servo motor can accurately achieve displacement control is mainly because of the encoder. The encoder can check the pulse between the drive and the motor motor, and if so, allowing the motor to work strictly in accordance with the PLC instructions, whether it is displacement movement, torque change, or speed change.
