What is the difference between Synchronous servo motor and Asynchronous servo motor??
If I’m not mistaken, I believe an asynchronous servo motor is an induction motor. Its torque is generated by the difference in rotational velocity of the rotor’s magnetic field and the stator’s magnetic field. AC voltage is applied to the stator and this induces a current in the rotor. These motors are usually used where high power is required. A synchronous servo motor uses a permanent magnet. The stator is similar to the induction motor but the rotor has permanent magnets mounted on it. The magenetic fields of the rotor and stator move independently but synchronously at the same rotational velocity. A torque is generated when a load is applied as the positional alignment of the rotor and stator is changed. The greater the positional misalignment, the greater the torque.
