Abstract
A motor vehicle electric motor assembly includes a motor housing having an annular wall extending from a housing first end to an opposite housing second end about a central axis to bound a cavity. The housing first end has a base configured to support a bearing housing. A motor shaft extends along the central axis between a shaft first end and a shaft second end. A rotor is fixed to the shaft for rotation about the central axis. A stator is supported by the annular wall in radially spaced relation from the rotor. A bearing is fixed in the bearing housing to support the shaft first end for rotation about the central axis. An end cover assembly is fixed to the housing second end. The end cover assembly has a motor shaft opening with a periphery of the motor shaft opening supporting the shaft second end for rotation about the central axis.
