Precision Motors

Other Details

Synchronous motors are basically stepper motors that are modified for AC operations. This makes the synchronous motors inherit most features of the stepper motor. The most important feature is to provide rotation at a fixed speed in synchronization with the frequency of the power source, regardless of fluctuation of the load or line voltage. The speed is hence synchronized to the line frequency of 50 Hz. Also since they rotate at very low speeds of 60 rpm when connected to AC mains, their pull-out and pull-in torques are nearly equal and very high.
