Patent ID: 8450898

Claim:
An insulator for a stator assembly including a stator core having a plurality of teeth, coils wound around the teeth, and a printed circuit board assembly (PCBA), the insulator comprising: at least a first insulator adapted to be mounted to the stator core and structured to insulate the stator core from the coils, said at least one insulator including structure to perform at least one additional function, wherein at least the first insulator includes an alignment and positioning structure adapted to align with an alignment and positioning structure provided to the stator core, the alignment and positioning structures providing reference points to properly align and position the first insulator to only a single mounting position with respect to the stator core, wherein the alignment and positioning structure of the first insulator includes a plurality of anchoring protrusions and the alignment and positioning structure of the stator core includes a plurality of holes adapted to receive respective anchoring protrusions, and one of the anchoring protrusions is structured to both self-adhere and precisely align the first insulator to the single mounting position.
