YE2(DSF)series three- phase asynchronous motors for subway tunnel fans

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  reliable operation, long service life, etc.. Motor in normal use can do S1 work system for continuous use,  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  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,  can meet the IE2 efficiency grades in IEC60034 -30 standard. The electrical parameters is the same as that of YE2 series motor.

Insulation System:

According to the design of class H (180 DEG C)  classC ( 220 DEGC)， in the rated output  direct power supply motor temperature rise according to 80K appraisal, 315 seat No.2, 4 pole  355 frame size motor temperature rise is allowed to reach 105K;

Cooling Method:standard cooling mode for IC410, IC411 self fan cooling, Wind driven by shaft extension end to cool the wind;

Motor 315- -355, 200  above 2 pole motor with standard oil nozzles,  more than 132 motor optional;

Material: cast iron castings; .

Standard installation structure of : IM B3, IM B5, IM B35 etc;

The motor can be used PTC  PT100 thermistor for winding protection, but also the installation of winding temperature measuring device,  frame 160  up

motor optional bearing temperature measuring device;

Special design: we can design special motor voltage  frequency according to customer requirements; can be adjusted according to customer requirements of motor appearance color.
