Abstract

An electric drive unit includes a housing, rotor shaft, motor, and plurality of bearings. The housing defines motor housing and gearbox regions. The housing has a bearing shield extending between the motor housing and gearbox regions and defining an aperture. The rotor shaft extends through the aperture from the motor housing region into the gearbox region. The motor is within the motor housing region and includes a stator and a rotor on the rotor shaft. The plurality of bearings are coupled with, and support and facilitate rotation of, the rotor shaft. The plurality of bearings includes every bearing of the electric drive unit that is coupled with, and configured to support and facilitate rotation of, the rotor shaft. At least one of (1) each of the plurality of bearings is outside of the motor housing region and (2) each of the plurality of bearings is within the gearbox region.
