1. Permanent magnet generator can operate at variable speed The electric excitation generator can only run at a constant speed. When the speed changes greatly, the AVR of the electric excitation generator will desperately increase the excitation current, and to a certain extent, the excitation coil will be burned. The rotor of the permanent magnet […]
