CHINA FACTORY MULTI-SPEED THREE-PHASE ASYNCHRONOUS MOTOR WITH ADJUSTABLE POLE YD SERIES FOR PUMPS AND FANS.ELECTRIC MOTORS YD90L-4/2, 1.3 / 1.8 KW SUPPLIERS, MANUFACTURERS AND FACTORY IN CHINA

For similar correspondent relationship between power rank and insulationdimensions, YD series motors are equivalent to other foreign advanced machines,and therefore they are machine with single-machine tool for export as well asspare motors for similar types imported from abroad.

1. PRODUCT INTRODUCTION OF ELECTRIC MOTOR

YD series designed according to IEC standard,are two or three speed motor,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. YD motors have 2 speed motor, 3 speed motor, 4 speed motor.

YD series electric motors can be widely used in such industry as machine tools, mining, metallurgy, textile, printing and dyeing, chemical industry, and agricultural machinery, etc.
