Permanent magnet industrial large ceiling fan

  The permanent magnets used in permanent magnet industrial large ceiling fans are both components of the magnetic circuit and a magnetic source in the motor. Advantages of permanent magnet generators:

1 simple structure, high reliability, permanent magnet generator used in permanent magnet industrial large ceiling fan eliminates the brush, excitation winding, collector ring structure, so the whole machine structure is simple, avoiding the excitation generator excitation winding easy to break, burn, collector ring, brush easy to wear and other failures.

2 specific power, small size, permanent magnet generator used in permanent magnet industrial large ceiling fan uses simplified rotor structure, there are two kinds of series magnetic field structure and parallel magnetic field structure: the rotor of series magnetic field structure adopts steel structure, permanent magnet embedded on the surface, strong magnetic induction strength on the rotor surface, and the overall structure is firm and reliable. The rotor of the parallel magnetic field structure is made of casting and pressing, and the permanent magnet is embedded in it at a high speed.

3. Good low-speed power generation performance and high output power. The permanent magnet generator used in the permanent magnet industrial large ceiling fan has good low-speed power generation performance.

4 high voltage stabilization accuracy, can extend the service life of the battery, permanent magnet generator used in permanent magnet industrial large ceiling fan uses small current pulse charging, and the use of switching rectification and voltage regulation mode, prolongs the service life of the battery, avoids the possibility of overcurrent charging and damage to the battery.

5 No wireless interference, the permanent magnet generator used in the permanent magnet industrial large ceiling fan has no collector ring, no brush, and no electric spark is generated in operation, which greatly improves the performance of use.

6 low noise, permanent magnet motor used in permanent magnet industrial large ceiling fan uses magnetic power, there is no sound generated by motor speed, not motor motor power.
