YD Series Pole-changing Multi-speed Three-phase Asynchronous Motor

In order to solve the three major problems of the traditional motor: large size, heavy weight and large noise, Waland researched and developed series YD pole-changing multi-speed three-phase asynchronous motors. They have the odds of high efficient, energy saving, small size, light weight, low noise, small vibration and so on.
The series have the same appearance with series Y and Y2 motors. The power level and mounting conform to IEC and DIN standards. Insulation class is B(optional F and H), and protection degree on enclosures is IP44(optional IPS4, IPS5, IPS6). Series YD can add YDEJ electromagnetic brake  pole-changing multi-speed three-phase asynchronous motors. 

Series YD motor achieves variable speed by changing the wiring method of the conventional stator winding to change the number of poles of the motor. With the different requirements of the load, it can change the power and speed characteristics step by step, so as to match with the load and facilitate the simplified transmission system, saving energy at the same time.
