The series motors comply with the applicable IEC or European standards. The motors also comply with various national standards.
The motors are totally enclosed, separate-fan cooled, IP55 degree of protection, temperature class F, IMB3 mounting arrangement (others available).
The motors are inverter-fed. Constant torque frequency range is 5 to 50 Hz. When frequency above 50 Hz is required, please be stated.
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 and low heat.
The motors are widely used at air blower, water pump, belt machine, machine tool etc. in the petrochemical industry, power industry, transportation industry, textile industry, mining industry etc.
