  • Systems and methods for constructing efficient permanent magnet motors
    Patent number: 11843285
    Abstract: Systems and methods for constructing a motor having a stator, and a plurality of rotor sections secured to a shaft which is positioned to rotate within a bore of the stator. Each rotor section has permanent magnets forming corresponding magnetic poles. Each rotor section has first and second inwardly facing keyways which are identically positioned in each rotor section and are configured to enable each rotor section to be alternately positioned in at least three distinct circumferential orientations with respect to a key of the shaft. A first subset of the rotor sections is secured to the shaft in a first one of the circumferential orientations, a second subset of the rotor sections is secured to the shaft in a second one of the circumferential orientations, and a third subset of the rotor sections is secured to the shaft in a third one of the circumferential orientations.
