Abstract
An interior permanent magnet synchronous machine includes a stator having electromagnetic windings and a rotor that is disposed concentric with the stator. The rotor has a plurality of rotor segments that include a first rotor segment and a second rotor segment. The first rotor segment is arranged to receive a first magnet set having first magnets that are disposed at a first pole-arc angle relative to each other. The second rotor segment is axially stacked relative to the first rotor segment along a rotor axis. The second rotor segment is arranged to receive a second magnet set having second magnets that are disposed at a second pole-arc angle relative to each other. The second pole-arc angle is different than the first pole-arc angle.
