YD Series variable pole multi-speed three-phase asynchronous motor



YD series varible pole multi-speed three-phase asynchronous motors are one of the main series products deriving from three-phase series .This kind of motor can change rotational speed to meet the requirements of load state,so that they can property match the demands of power and simplity adjustable speed system .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.
For similar correspondent relationship between power rank and insullation dimensions,YD series motors are equivalent to other foreign advanced machines ,and therefore they are matching with single-machine or machine tool for export as well as spare motors for similar types important from abroad.
