The three-phase asynchronous motor for subway tunnel fan is a three-phase asynchronous motor specially developed by our company to support the subway tunnel fan. The motor design concept is advanced, with compact structure, high energy efficiency, low noise, low vibration, stable reliable operation, long service life so on. The motor can be used continuously as S1 working motor in normal use, can also run normally for 2 hours in high temperature environments, such as 300 degrees Celsius ambient temperature. As a driving equipment supporting the subway tunnel fan, it provides reliable ventilation smoke exhaust facilities for all kinds of subways, hotels large buildings.

YE3 (DSF) high-efficiency three-phase asynchronous motor for subway tunnel fan under rated load efficiency meets the level 2 energy efficiency requirements of GB18613-2012, can meet the IE3 efficiency level of IEC60034-30 standard; Electrical parameters are the same as those of YE3 series motors.
