High efficiency motor

High efficiency design for energy saving purpose, which confirms to relevant requirements and rules of JB/T10391-2002 and IEC standards

Be made of selected qualified die casted aluminum-alloy materials.

Good performance, such as high safety, energy saving, light weight, small volume, low noise, little vibration, big breakaway torque, reliable operation, stable running and convenient maintenance.

Light weight, small volume and simple construction.

The foot can be removable and various mounting modes are available.

Be widely used in many fields, such as pumps, fans, ventilators, mixer, crushers, agitators, compressors, machine tools, food machines, transport machines, agriculture machines etc.

Can be equipped with PTC if requested.

Labeling Standards

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

Example: ME2 90 L – 2

ME2—means high efficiency electric motor

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

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

2—the forth part means the motor poles, this is a 2 poles motor, synchronous speed is 3000 r/min (50Hz); 3600 r/min (60Hz)
