Abstract
An insulator for a stator assembly includes at least a first insulator adapted to be mounted to the stator core and structured to insulate the stator core from the coils. The at least one insulator includes structure to perform at least one additional function. For example, the structure may include a support member to support and/or locate the PCBA on the stator core, a wire guide to guide cross-over wires that form a connection between coils, and/or positioning structure to precisely position the PCBA with respect to the coils.
