Abstract
A motor control method and system are provided. The motor control method includes recognizing, by a controller, a driving signal for a motor and when the controller recognizes the driving signal, the controller determine a failure of multiple Hall sensors disposed within the motor, based on signals detected by the multiple Hall sensors. Additionally, when the Hall sensors in the motor are determined to be faulty, the controller identifies a faulty Hall sensor from among the multiple Hall sensors by analyzing respective frequencies of the signals detected by the multiple Hall sensors.
