ELECTRIC MOTOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18525279 titled 'ELECTRIC MOTOR

The abstract describes an electric motor with a rotor assembly, stator assembly, and bearings for supporting the rotor shaft and allowing rotation relative to the stator assembly.

• Rotor assembly includes a rotor shaft, rotor body, and magnets coupled to the rotor body.
• Stator assembly is at least partially received within the rotor body and includes a stator mount with a stator support portion and a motor support portion.
• Stator core assembly is fixedly supported by the stator mount and defines a central bore for the rotor shaft and stator support portion.
• Bearings support the rotor shaft for rotation relative to the stator assembly, with the outer race supported by the stator core assembly.
• Stator core assembly also defines a bearing pocket adjacent to the central bore.

Original Abstract Submitted

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.
