YD/YDT Series Pole-changing Multi-Speed Three-Phase Induction Motor

YD Series pole-changing multi-speed three phase asynchronous motors are one of the main derivatives from Y series. They have step changes of rotational speed to meet the requirements of load character, so that they obtain the advantages of suitable matching of power and simplify speed changing systems. For this reason they are worth calling ideal motive power for saving energy consumption in mechanical systems. They are widely used in such industrial and agricultural departments, as machine tools, mining, metallurgy, spinning and weaving, printing and dyeing, chemical industry, and agricultural machinery, etc. YDT series are specially designed for use on pumps, fans and the similar instruments. YD is from frame 80 to 280, 0.35-85kW. YDT is from frame 80 to 315, 0.17-160kW. They have 2, 3 or 4 speeds with varied combination of poles as per specific requirements.
