What are the advantages of permanent magnet generators?

1. The permanent magnet generator eliminates the loss of the excitation system and improves efficiency.
2. The permanent magnet synchronous motor eliminates the excitation winding and the excitation power supply and has a simple structure and reliable operation.
3. The permanent magnet synchronous motor has a compact structure, small size and lightweight.
4. The size and shape of the permanent magnet synchronous motor are flexible and diverse.
