AC motor power
AC motor three-phase system, as compared to the three-phase AC motor with single phase motor, both in performance and price of raw materials has obvious advantages. Single phase Motors three-phase Motors of the same power than small size, light weight, and low prices. Three-phase motors are self-starting capability. No starting torque of single-phase motor, in order to solve problems, some special measures are needed. Single phase motor torque the torque, noise is relatively large, but the power required is simple, especially in the family is so easy to use. Therefore small household electric motor with single phase motor and apparatus.
