ABSTRACT:
The invention provides an electric motor assembly having an electric motor with a first end and a second end spaced from the first end. The electric motor also includes a motor shaft extending along a first axis between a first tip cantilevered from the second end and a second tip spaced from the first tip along the first axis. The electric motor assembly also includes a worm gear disposed on the motor shaft between the second end and the first tip for rotation with the motor shaft about the first axis. The electric motor assembly also includes a housing having an internal surface with a first portion correspondingly shaped with respect to the first end to locate the electric motor in the housing. The housing also includes a second portion disposed along the first axis spaced from the first tip. The electric motor assembly also includes a first thrust bearing disposed between the first tip and the second portion. The first thrust bearing limits movement of the motor shaft along the first axis in a first axial direction.
