Abstract:
An electric motor assembly includes an outer rotor motor, a sensor, and a brake assembly. The outer rotor motor includes a stator and a rotor. The rotor at least partly circumscribes the stator and is rotatable relative to the stator about an axis. The rotor includes a rotor core extending radially outwardly to present axially opposite first and second sides, and a plurality of magnets supported relative to the rotor core. The sensor is operable to sense a condition associated with the electric motor assembly. The brake assembly is operably coupled to the rotor core to selectively reduce the rotational speed of the rotor. The brake assembly is positioned at least partly axially outward from the first side of the rotor core, and the sensor is positioned at least partly axially outward from the second side of the rotor core.
