YD Series Pole-Changing Multi-Speed Three Phase Asynchronous Electric Motor

YD series designed according to IEC standard, are double speed, three speed and four speed motors, ac motors, induction motors. The electric motorsare totally-enclosed fan-cooled squirrel-cage asynchronous three phase motors.The electric motor is mainly derived products of IE1 series motor. The electrical motor is connected by changing winding(change poles), achieve to obtain different output and speed, let motor match the mechanical equipment load. The YD series pole-changing multi-speed three-phase asynchronous electric motor is a derived series of the Y series electric motor in China, with the advantages including: excellent performance, elegant shape, good interchangeability with the overseas similar products. Its protective grade is IP44.

The model code of the YD series electric motor comprises four parts: the first part “YD “indicates asynchronous electric motor; the digits of the second part indicate the central height of the frame (which remains the same with footing as well as without); the English letter of the third part is the code of the frame length (S-short frame, M-medium frame, L-long frame), the digit after the letter is the code of the iron core length; and the digit after the hyphen is the fourth part which indicates the poles of the electric motor.

YD Series Pole-Changing Multi-Speed Three Phase Asynchronous Electric Motor Application

The motors are designed in three types: double speed, three speed and four speed. These speed rotes can be changed in stages. The motors are widely used on applications in the equipments where the changed rates in stages are needed, such as mechanism, mine, metallurgy, textiles, printing and dyeing, chemical industry, agricultural etc. They can also simplify or take the place of reducting gearbox in the mechanical drive lines. For similar correspondent relationship between power rank and insullation dimensions,YD series motors are equivalent to other foreign advanced machines ,and therefore they are matching with single-machine or machine tool for export as well as spare motors for similar types important from abroad.
