摘要： 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.
