The pull-out torque of a synchronous motor refers to the maximum torque it can produce before losing synchronism with the rotating magnetic field. At this point, the motor begins to decelerate and may lose its ability to maintain a fixed speed. Pull-out torque is a crucial parameter in motor design, indicating the motor’s robustness against sudden increases in load. It is essential for applications where the motor may experience varying or heavy loads. Engineers carefully consider pull-out torque to ensure the synchronous motor’s stable operation under diverse operating conditions.
