  • Publication number: 20260302846
    Abstract: An electric motor includes a rotor assembly with a rotor shaft, a rotor body fixedly coupled to the rotor shaft, and magnets coupled to the rotor body. A stator assembly is at least partially received within the rotor body and includes a stator mount having a stator support portion and a motor support portion. The stator assembly further includes a stator core assembly fixedly supported by the stator mount and defining teeth, windings forming coils on the teeth, and a terminal arrangement. The stator core assembly includes a stator core and an insulator, and the stator core defines a central bore receiving the rotor shaft and the stator support portion. The terminal arrangement includes terminals mechanically and electrically connected to the windings and supported on a cylindrical end wall protruding axially from the insulator at an inner periphery of the insulator.

  • Patent number: 12689249
    Abstract: An electric motor includes a rotor assembly including a rotor shaft, a rotor body fixedly coupled to the rotor shaft, and a plurality of magnets coupled to the rotor body. The electric motor also includes a stator assembly at least partially received within the rotor body. The stator assembly includes a stator mount including a stator support portion and a motor support portion. The stator assembly also includes a stator core assembly fixedly supported by the stator mount, the stator core assembly defining a central bore that receives the rotor shaft and the stator support portion. The electric motor also includes a bearing having an outer race and an inner race, the outer race being supported by the stator core assembly, and the inner race supporting the rotor shaft for rotation relative to the stator assembly. The stator core assembly further defines a bearing pocket adjacent to the central bore.
