    Abstract: An example stator includes a stator body that is generally cylindrical; and a plurality of posts that protrude axially from the stator body and are arranged in a circular array about a perimeter of the stator body. Each post of the plurality of posts may include: a first slot, a second slot that is disposed radially-outward from the first slot, and a partition wall that separates the first slot from the second slot. Respective first slots are aligned circularly to form an inward circular channel about an outer peripheral surface of the stator body, and respective second slots are aligned circularly to form an outward circular channel about the outer peripheral surface of the stator body, wherein the outward circular channel is insulated from the inward circular channel via respective partition walls of the plurality of posts.

    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.
