Abstract:
1. An insulator for a stator assembly including a stator core having a plurality of teeth, coils wound around the teeth, and a PCBA, the insulator comprising: at least one insulator adapted to be mounted to the stator core and structured to insulate the stator core from the coils, each insulator including a main wall having a plurality of petals that correspond to a number of teeth on the stator core, said at least one insulator including structure to perform at least one additional function, wherein said structure includes a wire guide to guide cross-over wires that form a connection between coils, wherein the wire guide is provided along a periphery of the main wall and defines first and second slots adjacent each of the plurality of petals, each first slot being positioned and arranged to allow a cross-over wire to enter on one side of the associated petal and wrap around the petal and associated tooth to form the coil and each second slot being positioned and arranged to allow the cross-over wire to exit on the other side of the petal and cross-over to another coil, wherein the first and second slots adjacent a first petal include a same depth which is different than the depth of the first and second slots of the adjacent petal.
