Abstract: A rotor assembly is disclosed, including a rotatable rotor shaft defining a central axis, the rotor shaft coupled to a rotor core, the rotor core including a plurality of rotor pole pieces circumferentially located about the central axis, each pair of adjacent pole pieces being separated by a space, said rotor core comprising a plurality of core magnets located in the spaces separating the adjacent pole pieces; at least one magnet retainer plate positioned adjacent the rotor core and connected to the rotatable rotor shaft, the at least one magnet retainer plate including a plurality of circumferentially spaced magnet slots and balancing slots located between adjacent magnet slots, the balancing slots configured to receive a balancing weight; and, compression springs located in the balancing slots, each compression spring located adjacent a respective core magnet when the at least one magnet retainer plate is located adjacent the rotor core.

Abstract: A motor assembly having a stator assembly and a rotor assembly for an electric motor assembly is disclosed. The stator assembly includes at least two stator arms. Each stator arm including: a distal portion having an inner surface and a plurality of stator teeth spaced along the inner surface of each of the at least two stator arms, the distal portions collectively defining a stator opening, the opening having a longitudinal axis, and, a conductor portion located proximate to the distal portion, the conductor portion non-axisymmetric relative to the longitudinal axis of the opening; and. The rotor assembly is located in the opening proximate the stator teeth.
