Abstract

An example electric motor includes a housing, a stator fixed relative to the housing, a rotor, a brake assembly, a first bearing, and a second bearing. The rotor has a hub portion, a cylindrical portion, and a disk portion. The hub portion of the rotor has a first end, a second end, and a through hole therethrough. The brake assembly is fixed relative to the housing and configured to selectively couple the disk portion of the rotor to the housing. The first bearing is mounted between the first end of the hub portion of the rotor and the disk portion of the rotor. The second bearing is mounted between the second end of the hub portion of the rotor and the disk portion of the rotor.
