Abstract
A stator assembly for an electric motor includes a stator carrier that extends along an axis between a first side and a second side and defines an opening. A tab is located on one of the first side or the second side, the tab defines a first connection aperture. A plurality of windings are located in the opening and at least one bus bar is in conductive communication with the plurality of windings. A bus bar carrier includes a body that supports the at least one bus bar. The body includes a projection extending towards the tab that defines a second connection aperture. A connector extends through the first and second connection apertures to attach the projection to the tab. The connector is selected from a group comprising a rivet, a bolt, or a welded plastic piece.
