US Classification:

310194, 310214, 310215

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.

US Classification:

12820525, 12820418, 417321, 4174237

Abstract:

A blower includes a housing including an inlet and an outlet, a stationary component provided to the housing, an impeller positioned between the inlet of the housing and the stationary component, and a motor adapted to drive the impeller. The housing and the stationary component cooperate to define a volute that directs air towards the outlet. The housing includes a separating wall constructed and arranged to divide the volute into a high speed airpath region and a low speed airpath region.
