Features: Mainly used in double power switch, electric advertisement, mahjong table, electric screen machine, over-molding machine, counting machine, barbecue equipment, etc. Steady-state operation, the rotor speed and grid frequency has 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 constant and 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. It is a great replacement for the damaged motor.
