Wonder motors are mainly applied to air compressors, including screw air compressor, piston air compressor, and etc. We cooperated well with some world-renowned brands of air compressors. With large starting torque, and can tolerate the voltage and frequency fluctuation to some degrees. Sufficient heat resistance, the use of F class insulation material, avoid the totally enclosed type and rotary type air compressor operation conditions, resulting in electric motor temperature rise, accelerated ageing of insulating material, resulting in the damage to the motor. Withstand voltage fluctuation, resistant to vibration and impact. We optimize the electromagnetic coil of electromagnetic scheme, and use the best winding material to make sure the motors have good mechanical strength. At the same time, the voltage fluctuation range is 10% ~ + 15%, ensure the normal starting operation.
