three speed electric motor

Through the design of special stator winding, three sets of windings of a motor can be realized. Each winding corresponds to a pole number, that is, a speed, and three speed switches can be realized through transfer switches. It can also be designed as a single winding three speed, each phase winding section, through the conversion connection way to change the pole, to achieve the three speed switching. Such as 4/6/8 pole motor and so on.
