An electric motor assembly includes a rotor, a stator, and a gear assembly. The gear assembly includes a drive gear, a ring gear, and an intermediate gear disposed between and engaging each of the drive gear and the ring gear. The gear assembly further includes a carrier supporting the intermediate gear and being fixed relative to the stator so as to be stationary relative thereto. The ring gear is rotatable relative to the carrier and the stator.

Motor assembly with compact gear drive

An electric motor assembly includes a rotor rotatable about an axis and a stator spaced radially away from the rotor. An isolation housing, configured to permit magnetic flux to flow therethrough between the rotor and the stator, is disposed between the rotor and the stator and defines an internal rotor chamber, in which the rotor is located. The isolation housing fluidly isolates the internal rotor chamber from the stator. An encapsulating cover is provided that radially and axially surrounds the stator. The cover is formed of a resin material and bonds the stator to the isolation housing to prevent relative movement therebetween.
