ELECTRIC MOTOR

1 . A bobbin for supporting a winding on electric motor stator laminations, the bobbin comprising:

a first flange member;

a second flange member substantially parallel to the first flange member;

a winding hub including an inner hub portion coupled to the first flange member and a flared portion connecting the inner hub portion to the second flange member such that a winding span defined between the first flange member and the flared portion tapers from the second flange member to the inner hub portion, an inner surface of the winding hub defining a bobbin aperture for receiving stator laminations of the motor; and

a rib member coupled to the inner surface and extending into the aperture for engaging the laminations.

2 . The bobbin of claim 1 , wherein the aperture has a polygonal profile.

3 . The bobbin of claim 2 , wherein the aperture has a rectangular profile.

4 . The bobbin of claim 1 , wherein the aperture is configured to receive a radial tooth of a stator lamination.

5 . The bobbin of claim 4 , wherein the flared portion is configured to substantially conform to a profile of the stator lamination.

6 . The bobbin of claim 1 , further comprising an electrically conductive terminal for coupling the bobbin to a printed circuit board (PCB).

7 . The bobbin of claim 4 , wherein the terminal extends from an edge portion of the first flange.

8 . The bobbin of claim 1 , wherein the rib extends from the inner surface in cantilever fashion.
