Product Introduction


DSF series three—phase asynchronous motors for subway tunnel fans are developed by our company independently, which is designed to be used for supporting the three-phase asynchronous motors of the subway tunnel fans. Advanced design concept, with a compact structure, high energy efficiency, low noise, small vibration, stable and reliable operation, long service life, etc.. Motor in normal use can do S1 work system for continuous use, and in the high temperature environment, such as 300 degrees Celsius environment temperature can also normally run for 2 hours. As the driving equipment in the subway tunnel, for all types of subway, hotels, large buildings to provide reliable ventilation and smoke exhaust facilities.

YE3 (DSF) high efficient three—phase asynchronous motors 's efficiency confirms to the two level of energy-saving estimate value specified in GB18613-2012, and can meet the IE3 efficiency grades in IEC60034-30 standard. The electrical parameters is the same as that of YE3 series motor.
