  • Apparatus for an electric machine
    Patent number: 12470097
    Abstract: A rotor assembly for an electric machine has a rotor and magnets configured to form rotor poles that each have a central pole axis extending in a radial direction from a longitudinal axis. The rotor poles each have a first magnet layer having one or more first magnet including a central first magnet having a first transverse axis disposed perpendicular to the central pole axis. The rotor poles each have a second magnet layer radially inset from the first magnet layer and having two or more second magnets that include a pair of inclined second magnets each having a first transverse axis extending at an acute angle to the central pole axis. In relation to the central pole axis, a portion of each inclined second magnet is disposed inboard of an end of the central first magnet.
