Abstract

An enclosed pump motor includes an aluminum housing made by an impact extrusion process. The housing is cylindrical having an integrally-formed closed end with integral fastener bosses for attaching a pump thereto and an integrally-formed thickened cylindrical portion defining a shaft bore for receiving the motor shaft therethrough. At the other end, the cylindrical housing is open for receiving the motor therein. A motor cover is attached to the motor receiving end of the housing by crimping or bending a part of the housing into indents formed in the housing. The motor cover includes a threaded bore adapted to receive a threaded grommet wherein three connector pins are imbedded. The connector pins are connected to electrical power carrying conductors and/or switch conductors leading to a fluid level sensor switch. The conductor-to-pin connections are imbedded within the grommet and are hermetically sealed therein. The connector pins extend into the housing and are electrically connected to corresponding connectors leading to the electric motor.
