YD series IEC 3-phase asynchronous motor is a main derived series of Y series 3-phase asynchronous motor. It can change the rotating speed according to the demand of load，so it can match up the power reasonably and simplify the speed system and is considered to be ideal drive which can save energy. It is widely used in machine tool, mine, metallurgy, textile, printing and dyeing, chemistry and field machine etc., it is of full close type, IP44 protective grade and S1 running manner. The basic installing types are IMB3,IMB5,IMB35 etc. Installing dimension and whole dimension are the same as Y series corresponding machine
