A brake is provided. The brake may include a rotor having a plurality of magnets and a plurality of ferromagnetic poles radially disposed thereabout, and a stator having a plurality of shunts and a plurality of teeth radially disposed thereabout. At least one of the plurality of shunts and the plurality of teeth may be configured to selectively move between an engagement state and a free engagement state. The teeth may be configured to generate magnetic flux with the ferromagnetic poles so as to generate a braking torque during the engagement state. The shunts may be configured to redirect the magnetic flux therethrough and reduce the braking torque between the teeth and the ferromagnetic poles during the free engagement state.
