T-223D HOUSING FOR ELECTRIC MOTOR ASSEMBLY A B S T R A C T Apparatus and a method are disclosed for assembling an electric motor in which a unitary housing includes a base section having integral upright end walls. Each end wall is provided with a circular opening which openings are in coaxial alignment. A curable epoxy compound coats the surfaces of the base section and/or end walls for bonding a stator assembly within the unitary housing. The stator assembly is provided with a central bore which is axially aligned with the circular openings by having an alignment pin extending therethrough while the epoxy is in a pliable state. The epoxy is then cured with the alignment pin in position. After curing the pin is removed. The stator is now rigidly attached to the housing with its bore and the openings precisely aligned along the common axis of the motor. A rotor subassembly is inserted lengthwise through the openings and the stator bore with its bearings located in a corresponding opening on the housing for rotatable free support of the rotor in the bore. The rotor is axially retained by a set of retainers fixedly mounted within the openings.
