Description
he series motors are energy-saving product, special designed for beam-pumping unit.
The motors are totally enclosed, fan-cooled, IP54 degree of protection, temperature class F, IMB3 mounting arrangement, 50Hz frequency, 380 rated voltage (660/1140V available).
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.
