small ac electric motors
DSF series three—phase asynchronous motors for subway tunnel fans are developed by Suzhou Deneng Electric motors Co.,ltd. 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.
YE2 ( DSF ) series three-phase asynchronous motor ,s efficiency confirms to the three level of energy-saving estimate value specified in GB18613-2012, and can meet the IE2 efficiency grades in IEC60034-30 standard. The electrical parameters is the same as that of YE2 series motor.
