The series motors are energy-saving product, special designed for compressor.
The motors are totally enclosed, fan-cooled, IP54 degree of protection, temperature class F, IMB3 mounting arrangement, 50Hz frequency, 10kV rated voltage.
The motors have rated efficiency above IE4. The motors, at different load, still have much more high efficiency than three-phase induction motor. The motors also have high power factor, small current, low heat and line-start ability.
