Abstract
A method and system for computing a motor speed and a rotor position using a hall sensor are provided. The method improves precision for computing the speed of the motor rotating at a high speed and the rotor position using the hall sensor based on configurations, such as the hall sensor mounted in the motor as a position sensor, a motor controller configured to receive a signal of the hall sensor to operate the motor, and a microcomputer configured to store a time when the motor controller senses the timing of a change in the signal of the hall sensor.
