Non-standard automation equipment servo/stepper motor application, precision, control mode
The rotor inside the permanent magnet synchronous servo motor is a permanent magnet. The U/V/W three-phase electricity controlled by the driver forms an electromagnetic field, and the rotor rotates under the action of this magnetic field. At the same time, the encoder in the motor gives feedback signal to the driver, and the driver adjusts the rotation Angle of the rotor according to the feedback value and the target value. The accuracy of the servo motor depends on the accuracy of the encoder (number of lines).
