Introduction          

YD series variable poles multi speed three phase asynchronous electric motors are one of the main products derived from Y series three asynchronous electric motors. its has the same structure, installation method and frame size as the Y series. YD series two-speed motor is single winding, three-speed motor is dual winding. The motor change the poles by changing the connection of stator windings, so that use one or two winds to obtain two or more speed. it can be used in kinds of transmissions which need gradual changing speed, mainly used in cutting tools and mining and metallurgy, textile, printing and dyeing, chemical, agricultural and other industries.
