0.75-800 kw 1-1000 hp Frequency inverter motor

Frequency Inverter Motor

Be specially designed for the energy saving and other special requirement, and conform with the relevant GB/T 21209-2007 and IEC standard, which is totally enclosed and fan-cooled type.

Can adjust the speed in wide range. They are: stepless speed regulation of 5(3)~100Hz, constant torque regulation of 5(3)~50Hz.

With strong overload capability, which can reach 160% of the rated torque in 1 minute.

With good performance at low speed that torque is smooth and no crawling circumstance exists.

With many advantage of high efficiency, long working life, energy saving, high starting torque, low noise, small vibration, big breakaway torque, reliable performance, convenient  maintenance.

Be widely used in many fields, such as machine tools, pumps, fans, transport machinery, mixer, agriculture machinery, food machines, agitator, air compressor etc. We also can supply aluminum housing type for 132 frame size and below.

Equipped with re-greasing system when the motor frame size is 160MM and above

Can be equipped with PTC if requested.

Labeling Standard

Series Code + Frame Size + Iron Core Length No. + Motor Poles

Example: YVP2 132 M – 4

YVP2—means variable frequency motor

132—the second part means the height of motor center (when the motor has no foot, it is same to motor with foot)

M—the third part means the base iron core length no.(S-Short Base, M-Medium Base, L-Long Base)

4—the forth part means the motor poles, this is a 4 poles motor, synchronous speed is 1500 r/min (50Hz); 1800 r/min (60Hz)
