Abstract
A motor for a laundry appliance includes a drive shaft coupled to a drum at a first end. The rotor frame is coupled proximate the second end of the drive shaft, where the rotor frame includes at least one polymeric material. A central hub includes a core and a perimetrical ring that extends circumferentially around the core. A plurality of recesses are defined within a planar surface of the perimetrical ring, wherein a portion of the polymeric material is received within the plurality of recesses to secure the rotor frame to the central hub.
Claims20
A motor for a laundry appliance, the motor comprising:
- a drive shaft coupled proximate a drum at a first end;
- a rotor frame coupled proximate a second end of the drive shaft, the rotor frame including at least one polymeric material;
- and
- a central hub comprising:
- an outer perimetrical ring that defines a cylindrical outer surface;
- a plurality of recesses positioned within an inner surface of the outer perimetrical ring;
- and
- a core that receives the drive shaft, wherein the core is positioned between the plurality of recesses and the drive shaft, wherein the at least one polymeric material is received within the plurality of recesses defined between an outer surface of the core and the inner surface of the outer perimetrical ring to secure the rotor frame to the central hub.
A rotor for a motor for driving a laundry appliance, the rotor comprising:
- a rotor frame including at least one polymeric material;
- a central hub comprising:
- a core defining a core outer surface;
- an attachment portion that is defined by the core outer surface;
- an outer perimetrical ring positioned outside of the core and having an inner surface that further defines the attachment portion, wherein the at least one polymeric material is received within the attachment portion defined between the core outer surface and the inner surface of the outer perimetrical ring to secure the rotor frame to the central hub.
A motor for a laundry appliance, the motor comprising:
- a drive shaft coupled proximate a drum at a first end;
- a rotor frame coupled proximate a second end of the drive shaft, the rotor frame including at least one polymeric material;
- and
- a central hub comprising:
- a core that receives the second end of the drive shaft;
- an attachment portion extending concentrically around an outer surface of the core;
- an outer perimetrical ring positioned concentrically outside of the core, wherein an inner surface of the outer perimetrical ring further defines the attachment portion, wherein a portion of the at least one polymeric material is received within the attachment portion to secure the rotor frame to the central hub.
