  • Surface-mounted high-speed permanent magnet synchronous rotor
    Patent number: 11735966
    Abstract: A surface-mounted high-speed permanent magnet synchronous rotor includes a rotor shaft, multiple permanent magnet sets, multiple silicon steel piece sets and a rotor iron core sleeve. The multiple permanent magnet sets and the multiple silicon steel piece sets are glued on a surface of the rotor shaft along an axis of the rotor shaft. The multiple permanent magnet sets and the multiple silicon steel piece sets are spaced around the rotor shaft. The multiple permanent magnet sets have a same outer diameter as the multiple silicon steel piece sets, and the multiple permanent magnet sets and the multiple silicon steel piece sets are sleeved with the rotor iron core sleeve.
