Abstract

Systems and methods for braking a power-driven shoe during an emergency scenario are described. An illustrative system may include a brushless direct current motor wherein each winding is interfaced to an emergency braking circuit. The emergency braking circuit may be configured to short each of the winding to ground which creates torque force opposite to the current motion of the motor, thus quickly decelerating the motor.
