Compared with other motors, it is obvious that servo motors have many advantages, such as fast response speed, high work efficiency, good stability, and strong energy-saving. This type of product has been greatly welcomed and has become one of the most favored motors for users. Therefore, the application range of servo motors is also relatively wide.
The control and driving technologies in servo motors have achieved intelligence and digitization. Although there is no essential difference in principle between them and single-phase induction motors, AC servo motors can overcome the self rotation phenomenon of AC servo motors. That is to say, when there is no control signal, the servo motor will automatically stop rotating.
The rotor inside the servo motor is a permanent magnet. When the rotor rotates under the action of this magnetic field, the motor's built-in encoder will feedback a signal to the driver. After comparing with the target value, appropriate adjustments will be made to the rotor's rotation angle, thereby greatly improving the control effect.
