    Abstract: A motor for an electric vehicle includes a motor housing for receiving a stator. A plurality of caps each have an outer rim and a washer portion defining a bolt receiving opening. The outer rim of each of the caps is press-fit into the receptacles in the motor housing. The caps are each attached to the stator by one of the bolts. The heads of the bolts clamp the cap to the stator to retain one end of the stator. The outer rim holds the cap in the motor housing while the washer portion flexes axially in response to thermal expansion and contraction of the motor housing. A method is disclosed for assembling the stator into the motor housing.
