YD Rewinding Submersible Electric Motors

YD Series Electric Motor

Introduction about the YD Series induction motor:

Three phase totally enclosed fancooled motors /YD series electric motor

YD series multi-speed three phase motor are designed and manufactured under incorporating the advantages of the counterparts in the word. And are in full conformity with IEC. This AC motor employs method of changing the pole numbers so as carry out speed adjustment, the series motors have features of small volume, light weight, low nosie, well starting performance, reliable operation, convenient maintenance, the main technical indexs have reached the international standard.

1. YD series motors, there are many distinguished features, small size, light weight, satisfactory performance, easy to control and reliable in operation, as compared 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 purpose or special combination machine tools, blower, pumps and other kinds of devices whose speed needs to be changed.
2. YDseries pole-changing multi-speed three-phase induction motors are derivatives of Y series motors, and have the same protection degree, overall and mounting dimensions as those of Yseries motors.
3. YD series motors have three types: Double-speed and four-speed by pole changing. Tyey are sutitable for mechanicalequipements for step speed regulation, such as machine, tools, mines, metallurgy, chemical industry and textile.

YD series(IP54)electrode-varied and multi-speed three phase asynchronous motor can change the rev with loading request, therefore, it can efficienty distribut the power and simplify the shift device. This series adapt to every kind of drive machine that need multi-speed. For example, machine tool cutting, mining and metallurgy machinery, spinning machinery, printing and dyeing machinery, chemical machinery, agricultural machinery.
YD series variable-pole multi-speed three phase induction motor is one of the main derived series of Y series three phase induction motor, a national unified designed latest product in China and a replacement type for the JDO2 series. The speed of this series motor can be changed step by step according to the requirements of load characteristics, thereby reaching the aims of economizing on electricity and simplifying the system of speed variation. This series of motor has great starting torque and low noise and vibration, and its mounting dimensions are complied with the standard of IEC. It has a fairly good interchangeability as compared with the similar products of the same kind, so that it is easy to maintain and widely used in the industrial departments of machine tools, chemical industry, textile, metallurgy and mine, etc.

The protection degree of motor is IP44, IP54, IP55, cooling mode is of IC0141, and B-class insulation is adopted, the mode of rating is continuous running.
