摘要：An electric machine includes a stator and a rotor disposed adjacent the stator. The rotor may be rotatable around a rotor rotation axis. The rotor may include a rotor core and a plurality of permanent magnets. The plurality of permanent magnets may include a permanent-magnet cluster disposed at least partially within the rotor core. The permanent-magnet cluster may be configured to create a magnetic pole of the rotor. Additionally, the permanent-magnet cluster may include multiple radial permanent-magnet layers. The rotor may also include one or more axially-extending channels located in a portion of the rotor core disposed between adjacent radial permanent-magnet layers.
