The AC synchronous motor gets constant under the rated frequency, and it's not affected by voltage. At a steady state, the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integral number of AC cycles. In the steady-state operation, the rotor speed and grid frequency have a constant relationship between n-ns-60f/p, ns known as the synchronous speed. If the frequency of the grid is constant, then the steady-state synchronous motor speed is constant and it is independent of the size of the load. Regardless of the size of the load, as long as the step does not lose speed will not change. Our motors are made of pure copper wire and metal gears for the best performance. This Motor is a 220V AC-operated synchronous gear motor. It can run in a clockwise as well as counter-clockwise direction.
