YD series Pole Changing Multi-speed Three-phase Asynchronous Motor
Outlines
YD series pole changing multi-speed asynchronous motor is one of the series products derived from the three-phase asynchronous. They have step changes of rotation as speed to meet the requirements of load character, so that they obtain the advantages of suitable matching of power and simplify speed-changing systems. They are widely used in such industrial and agricultural departments, as machine tools, mining metallurgy, spinning and weaving, printing and dyeing chemical industry, and agricultural machinery, etc.
YD series motors can match other foreign advanced machines of similar type in power grades as well as in correspondent relation ship between power grades and mounting dimensions, and therefore they can substitute for the latter so as to be used to fit machine tools or single motors for export as well as spare motors for electric machines of similar types in imported equipment.

Contour and installation dimensions
Its extemal dimensions and mountiong dimensions are the same with teh Y series three-phase asynchronous motor.
