Patent ID: 8198780

Claim:
A stator for an electronically commutated DC motor, the stator comprising: a plurality of individual stator poles, each of said stator poles including a pole core, pole shoes and return sections, each of the return sections of the stator poles having first and second profiles that intermesh with each other so that they together form a hollow cylindrical return with a periphery, in which the pole cores connected to the return sections are directed radially inward; an insulation and a winding provided on each of the individual stator poles; and a retaining part that does not serve as part of a motor housing, wherein the retaining part is a metal clamping ring, the clamping ring including a hollow cylinder; a plurality of perforations spaced about the hollow cylinder defining spaced bridges and connectors which connect two ring areas on the entire periphery to each other, the clamping ring being positioned so that it is under bias around the entire periphery of the hollow cylindrical return and tightens the stator poles relative to each other.
