Abstract
A method of calculating a motor position uses a hall sensor. The method can include determining a motor position in response to a signal change of a hall sensor installed to a motor, calculating a basic compensation value for compensating a motor position error due to signal measurement delay of the hall sensor, determining whether a current command condition for a constant-speed operation of the motor is satisfied, calculating a first-up compensation value and a first-down compensation value, calculating an average values of the deviation between d-q axes current commands, and correcting the motor position using the basic compensation value when a difference between the average values is less than a reference average value.
