High temperature fire exhaust fan series three-phase asynchronous motor is a fully enclosed single speed motor independently developed by Suzhou Deneng Motor Co., LTD. Advanced motor design concept; Fully considering the load characteristics of the smoke exhaust fan, it has the characteristics of compact structure, high energy efficiency, low noise, low vibration, stable reliable operation, long service life so on. The motor relies on the wind generated by the operation of the fan at the load end for cooling, the structure is more compact than that of the ordinary motor, which greatly saves the installation space provides strong support for the compact structure of the fan design. According to the needs of fire smoke exhaust environment, the motor designed for high temperature resistance can meet the requirements of the motor in CA211-1999 Test Method for High temperature Resistance of fire smoke exhaust fan, can run normally for 2 hours at 250 ° F ambient temperature, meeting the requirements of fire smoke exhaust motor.

YE2 (HTF) three-phase asynchronous motor for high temperature fire exhaust fan under rated load efficiency meets GB18613-2012 level 3 energy efficiency requirements, can meet IE2 efficiency level in IEC60034-30 standard; Electrical parameters are the same as those of YE2 series motors.

Main Performance Main Performance

• Rated Power Range:0.37-315KW • Rated Frequency: 50Hz

• Rated Voltage: 380V

• Motor Poles: 2, 4, 6

• International Protection Standard: IP54

Insulation system:

Designed according to grade F (155P), the temperature rise of the motor is assessed according to 80K when rated output direct power supply.

The temperature rise of the second fourth poles of the 315 frame the motor of the 355 frame is allowed to reach 105K;

Motor cooling mode: The standard cooling mode is IC416 forced air cooling, but it is equipped with fan load

When the low frequency does exceed 30Hz, the IC411 self-fan-cooling type can be selected;

Motor 315-355, 200 above 2-pole motor standard with oil injection nozzle, 132 above motor optional;

Casting material: cast iron; Standard installation structure types: IMB3, IMB5, IMB35, etc.

The motor can choose PTC PT100 thermistor for winding protection, the winding temperature measuring device can also be installed, [bearing temperature measuring device can be selected for motors above 60;

Special design: Suzhou Deneng Motor Co., Ltd. can design special voltage, frequency motor according to customer requirements; The appearance color of the motor can be adjusted according to customer requirements.

When the motor is adjusting speed to high frequency, it should pay attention to:

If it is a fan, pump load, it should be noted that the power of the load will increase when the frequency is higher, such as exceeding the rated power of the motor will cause motor damage; When the motor running speed exceeds the rated speed, the noise vibration value will increase, the bearing life will be shortened;
