The CJY30/9G(P) stringing type electric locomotive adopts the leading tech of VVVF AC frequency conversion variable voltage speed regulation, the big working rate IGBT unit will turn the direct current into three phase alternating current with adjustable frequency to drive the three phase asynchronous motor, for using the VVVF control tech, the three phase asynchronous motor will reach and go beyond the driving feature which will enable the car-loading lift powerful. Compared with the traditional direct current motor,it is unlikely to break, the touching part of the controlling is not worn and it can turn the electricity of speed killing into electricity returning. This tech of the motor is in leading position, new designing, safe driving, reliable and energy saving.

Working principle:

The stringing DC550V grid supplies frequency converters with electricity, the frequency converters turns the direct current into three phase alternating current, the three phase alternating current will drive the motor, and the locomotive will be driven by the transmission shaft.
