Tips: The Application Difference between Synchronous Motor and Asynchronous Motor
Synchronous motor can adjust the power factors flexibly through excitation while the power factors of asynchronous motor are not adjustable. Therefore, in some big factories with high asynchronous motor application, one synchronous motor can be equipped for phase adjustment, so as to adjust the power factors between the factory and network interface. However, since synchronous motor has manufacturing cost and large maintenance work amount, capacitance compensation power factor is generally used now.
Because synchronous motor has field winding and slip ring, the operation workers are required to have a high level to control excitation. In addition, compared with the free-maintenance performance of asynchronous motor, the maintenance work amount is great. Therefore, when used as the motor, asynchronous motor is mostly used.
