Advantages of Synchronous Motors. Synchronous motors offer several advantages, making them suitable for a wide range of applications. Here are the key benefits: Ability to maintain a constant speed; One of the major advantages of the synchronous motor is its ability to maintain constant speed under various load conditions.
MoreTherefore synchronous motor is not affected by any variation in the load. The Increase in load increase the torque. A synchronous motor will stall if the torque increase beyond the breakdown torque. Synchronous motor either run at synchronous speed or does not run at all. Synchronous motor can run in both leading as well as lagging power factors.
