The servo motor is also known as the executive motor. In an automatic control system, it is used as an execution element to convert the received electrical signal into an angular displacement or angular speed output
on the motor shaft.
The encoder does not control the servo, which detects the Angle or speed of the servo turn and transmits it to the servo driver, which adjusts the drive signal of the servo motor according to the data fed back by the encoder, increases the speed or stops.The servo drive, the servo motor and the encoder constitute a closed-loop control system.
Higher accuracy and stability: the servo motor realizes the closed loop control of position, speed and torque, which not only overcomes the problem of step motor in operation, but also provides sufficient guarantee for the production and processing of equipment in terms of accuracy and stability.
Servo motor especially suitable for applications requiring smooth operation, low noise, fast response, long service life and high output torque.
