Abstract

An electric motor-brake assembly includes a housing within which a rotor assembly, a stator assembly, and a brake assembly are disposed. The brake assembly is operable between an engaged state and a disengaged state. The rotor assembly is axially movable within the housing and is supported by bearings supporting both radial and axial loads. When the motor stator is de-energized, the brake assembly is in the engaged state to prevent the rotor assembly from rotating in at least one rotational direction. When the motor stator is energized, the brake assembly is in the disengaged state such that the rotor assembly is free to rotate. The brake assembly can include a friction pack that is engaged and disengaged by axial displacement of the rotor assembly.
