Abstract
A stator frame for an electric motor including a substantially cylindrical shaped body section having opposed ends, a cooling passageway extending through at least a portion of the body section, and at least one spacer bar. The cooling passageway includes a cooling conduit having an inlet port and an outlet port in flow communication with the cooling passageway. The spacer bar has a notched side and at least one finger extending therefrom such that the finger mechanically couples the spacer bar to the cooling conduit.
Claims15
A stator frame for an electric motor, said stator frame comprising:
- a substantially cylindrical shaped body section having opposed ends, and a cooling passageway extending through at least a portion of said body section, said cooling passageway comprising a cooling conduit;
- an inlet port and an outlet port in flow communication with said cooling passageway;
- and
- at least one spacer bar comprising a notched side and at least one finger projecting outwardly from said notched side, said at least one finger crimpable around said cooling conduit such that upon crimping said at least one finger extends circumferentially around said cooling conduit substantially surrounding said cooling conduit and mechanically coupling said spacer bar to said cooling conduit.
An electric motor, comprising:
- a stator frame comprising a substantially cylindrical shaped body section having opposed first and second ends, and a cooling passageway extending through at least a portion of said body section, said frame further comprising an inlet port and an outlet port in flow communication with said cooling passageway, said cooling passageway comprising a cooling conduit;
- a first end shield secured to said first stator frame end;
- at least one spacer bar mechanically coupled to said cooling conduit, said spacer bar comprising a notched side and at least one finger projecting outwardly from said notched side, said at least one finger crimpable around said cooling conduit such that upon crimping said at least one finger extends circumferentially around said cooling conduit substantially surrounding said cooling conduit and mechanically coupling said spacer bar to said cooling conduit.
