The measures to avoid the demagnetization of the motor permanent magnet, rational structure design and cooling system, to make sure the working temperature of motor under 90℃. Avoid the active demagnetization of permanent magnet. The natural aging is only 0.1% in 10000 hours.

Chemical stability: Oxidation prevention in production, with protective coating, galvanizing nickel plating, epoxy coating.


•Add a framework oil seal on the motor cover to stop the axial splash entering the motor.

•Add seals on the groove of the top cover of motor, to stop the water congealed by spraying device entering the wiring cavity from the bolt hole.

•Have adhesive sealing on the end cover and shell end face of motor, to stop the water enter the motor when soaking.



•Good corona resistant performance of windings after encapsulation, to solve the turn-to-turn short circuit in motor.

•Better heat conduction performance of windings after encapsulation. In comparison to “VPI vacuum dipping paint", , the temperature of motor will be lower of 40-50k.

•Better insulativity, improve the reliability.

•Improve the windings performance of mechanical strength, waterproof, dustproof, antifouling, and free of maintenance through its lifetime.










Improve the windings performance of mechanical strength, waterproof, dustproof, antifouling, and free of maintenance through

Simple power drive system - no gear box, energy saving, reliable and safe, easy installation, smaller volume;

High efficiency- the self-efficiency of motor is over 96% power factor can reach 99%;

Big starting torque - starting and parking in heavy load, the starting torque can reach 2.2 to 2.8 times of nominal torque.

Stepless speed regulating - Good performance on speed control, can regulate the speed automatically.

Excellent PF balancing function - balance the load of each motor, realize balanced power output.

Intelligent and digitization - complete protection against overvoltage, over current, under voltage, overheat etc. Realize the digital control of mine when unattended.

High comprehensive performance - high efficiency, low noise, no maintenance, good anti-corrosion and energy saving performance.
