Abstract
A BLDC motor, has a first sub-motor and a second sub-motor. The first and second sub-motors have independent input terminals and a common rotor, including a common output shaft. In a normal operating mode the two sub-motors operate together as one motor to output a normal operating power of the motor. In an emergency operating mode, when one sub-motor has become faulty and generates a braking torque, the normal sub-motor is operated to generate a torque to compensate for the braking torque produced by the faulty sub-motor.
