Introduction to Pole – Changing Two – Speed Three – Phase Motor
A pole – changing two – speed three – phase motor is a type of electric motor that can operate at two different speeds. This is achieved by changing the number of poles in the motor’s stator winding. The speed of a three – phase induction motor is directly related to the frequency of the power supply and the number of poles. By changing the pole configuration, the motor can switch between two distinct speeds, which provides flexibility in various industrial and commercial applications. These motors are widely used in fans, pumps, conveyors, and other equipment where different operating speeds are required to meet different load conditions. Pole-Changing Two-Speed Three-Phase Motor
