YD series pole-changing multi-speed three-phase induction motors

YD series pole-changing multispeed 3-phase motor is an entirely new prouct of Y series family, a modified design of JD02 series.

Product Features

The overall and mounting dimensions, insulaion class, degree of protection and method of cooling of the YD series motors are the same as the Y series motors. The mounting dimensions are in fully conformity with the IEC and DIN42673 standards. The rated output, starting performance, efficiency and power factor.

For these motors, there are many distinguished features, small size, light weight, satisfactory performance, easy to control and reliable running. Comparing with the JD02 series, YD motors have higher efficiency, higher power factor, higher starting performance and reduced level of noise and vibration.  

The Yd series pole-changing motors are suitable for driving general pupose or special combination machine tools, blowers, pumps and other kinds or devices which speed needs to be changed.

As for rated power, mounting type, bearings, terminal box, they can refer to the datas of Y series.

Conditions of Operation

The motors are assurred to give reliable service when used at:

(1) An altitude should not be over 1000 meters above sea level;

(2)An ambient temperature not exceeding +40°C.

Voltage, Frequency, and Duty:

Ambient temperature: to be altered with the change of seasons, but do not not exceed 40°C;

Altitude: Not exceed 1,000 meters.

Rated voltage: 380V,

Rated frequency: 50Hz;

Symbols for Mounting Arrangements:

(1)B3: Foot-mounted motor IM1001. IMB3

(2)B5: Flange-mounted motor IM300. IMB5

(3)B35: Foot and Flange-mounted motor IM1001. IMB3. and IM3001. IMB5.
