The magnetic flux leakage of the radial structure permanent magnet synchronous generator is small, and the rotor assembly process is simple.
The stator copper loss of the high-voltage motor is also smaller than that of the low-voltage motor
Enneng permanent magnet motor system uses low-speed, high-torque motor and controller to replace the original motor and frequency converter
The gearless permanent magnet motor drive system of variable frequency speed regulation can give full play to its advantages when applied to the belt transportation system in the coal mine.
