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.

An interior permanent magnet synchronous machine, comprising:
- a stator having electromagnetic windings;
- and
- a rotor that is disposed concentric with the stator and is disposed about a rotor axis, the rotor having a plurality of rotor segments, comprising:
- a first rotor segment being arranged to receive a first magnet set having first magnets that are disposed at a first pole-arc angle relative to each other, and
- a second rotor segment that is axially stacked relative to the first rotor segment along the rotor axis, the second rotor segment being 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 being different than the first pole-arc angle.
A rotor for an interior permanent magnet synchronous machine, comprising:
- a plurality of rotor segments that are axially stacked along a rotor axis, the plurality of rotor segments, having:
- a first rotor segment being arranged to receive a first magnet set having first magnets that are disposed within a first magnet pocket, the first magnets have a first magnet length that extends perpendicular to the rotor axis, and
- a second rotor segment that is axially stacked relative to the first rotor segment along the rotor axis, the second rotor segment being arranged to receive a second magnet set having second magnets that are disposed within a second magnet pocket, the second magnets have a second magnet length that extends perpendicular to the rotor axis and is different than the first magnet length.
