Abstract
Various implementations include a six-phase electric motor including an annular stator and a rotor. The stator defines an opening having an inner surface. First and second three-phase sets of concentrated windings are circumferentially spaced along the inner surface of the opening. The first and second sets of concentrated windings are circumferentially offset from each other. The stator defines voids located radially outwardly from, and circumferentially between, each of the windings. The rotor includes permanent magnets circumferentially spaced around the rotor axis. The outer circumferential surface of the rotor defines grooves located circumferentially between each of the permanent magnets. The rotor is disposed within the stator opening such that the stator and rotor are coincident with each other. Flux from the permanent magnets interacts with a stator magnetic field created by a current flowing through the first and second sets of concentrated windings to cause the rotor to rotate.
