ABSTRACT:
The apparatus of the present invention provides a stator for an electric motor. The apparatus includes a plurality of stator components assembled together to form a generally annular stator core. A wire is wrapped around at least a portion of the stator core to form a stator winding. A first generally annular end plate and a second generally annular end plate are mounted to axially opposite sides of the stator core such that the stator core is axially trapped and retained therebetween. A fastener applies a clamping load to the first and second end plates such that the stator core is compressed therebetween. The clamping load from the fastener is applied directly to the first and second end plates which distribute the clamping load to the stator core such that the plurality of components are held together without the fastener directly applying the clamping load to the stator core. A corresponding method for providing a stator is similarly provided.
