Abstract
An interior permanent magnet motor assembly including a stator and a rotor is provided. The stator includes electromagnetic windings. The rotor is disposed concentrically with the stator about a rotor axis and the rotor has a plurality of rotor segments. The plurality of rotor segments may include a first rotor segment and a second rotor segment. The first rotor segment may have first pockets being arranged to receive at least a first magnet of a first magnet set according to a first rotor topology. The second rotor segment may be axially stacked relative to the first rotor segment about the rotor axis. The second rotor segment may be arranged to receive at least a second magnet of a second magnet set according to a second rotor topology having a configuration that is different than the first rotor topology.
