Abstract
A method and a system for controlling a motor are provided to allow for a limp home function when an error occurs in a Hall effect sensor that detects the position of a rotor while operating a motor used for an automotive electric water pump. The method includes determining an output error of a Hall effect sensor and stopping adjustment a speed of the motor based on output of the Hall effect sensor, in response to detecting an output error of the Hall effect sensor. Additionally, the method includes adjusting the speed of the motor based on a counter electromotive force generated by a plurality of stator coils having different phases in the motor.
