An apparatus, including: a multi-phase motor having stator windings; an inverter connected between a direct current (DC) supply voltage and ground, and having power switches connected to the stator windings of the multi-phase motor; and a motor controller operable to regulate a braking torque of the multi-phase motor during periods of battery power unavailability by applying control signals to the power switches in the inverter to boost the DC supply voltage using back electromagnetic force (BEMF) voltage induced in the stator windings, passively brake the multi-phase motor, or plug brake the multi-phase motor, for each phase of the multi-phase motor, based on the DC supply voltage, a rotor position of the multi-phase motor, and an angular speed of the multi-phase motor.
