YD series change-pole multi-speed three-phase asynchronous motor is the electrical derivative of YE2 series three-phase asynchronous motor, The outline and installation dimensions, insulation grade, cooling mode are in line with international IEC standards, Power level, starting performance and force performance are similar to the level of international similar electric motors.

YD series uses the connection method of changing winding to change the number of poles and output of the motor, so that it matches the load characteristics of the equipment. The noise, starting torque, vibration and shape installation size are in line with IEC standards, it has the features of small size, light weight, reliable operation, solid structure, beautiful appearance and so on.

YD series can be combined with manual control, contactor, control device , it saves a lot of energy. The speed and output of the motor are changed by changing the connection of the winding to match the load characteristics of the equipment, which simplifies the transmission system and save much energy. YD series has two speeds, three speeds and four speeds, the pole ratio of 4/2, 6/4, 8/4, 12/6, 6/4/2, 8/4/2 and 8/6/4, 12/8/6/4 and other nine kinds, its main performance indicators reach the same level of international products.

YD change-pole multi-speed motor is mainly used for various transmission machinery such as machine tools, mining, metallurgy, textile, printing and dyeing, chemical and other industries, suitable for the equipment that require step by step speed regulation to match the nature of the load.
