A bobbin for supporting a winding on electric motor stator laminations includes a first flange member and a second flange member substantially parallel to the first flange member. A winding hub includes 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 defines a bobbin aperture for receiving stator laminations of the motor. A rib member is coupled to the inner surface and extends into the aperture for engaging the laminations.
