Special for pump and fan Variable frequency rare earth permanent magnet motor 0.75-55Kw

Principle:

     The three-phase symmetrical current passing through the three-phase winding of the stator will generate a stator rotating magnetic field. The rotating magnetic field of the stator generates current in the cage winding for the rotation of the rotor to generate the rotating magnetic field of the rotor. The asynchronous torque generated by the interaction between the stator rotating magnetic field and the rotor rotating magnetic field makes the rotor turn from stationary to rotating. After the start-up is completed, the rotor winding is no longer active, and the magnetic field generated by the permanent magnet and the stator winding interacts to generate driving torque.

     The product is a permanent magnet motor specially designed for fans,the efficiency index reaches the first-class standard of GB30253-2013 "Energy Efficiency Limits and Energy Efficiency Grades of Permanent Magnet Synchronous Motors",reach the international advanced level of similar products.
