Abstract
A motor control method that includes: calculating an ideal position of a motor rotor based on a Hall sensor signal; calculating a current position of the motor rotor based on a rotation speed of the motor rotor; and calculating a Hall sensor offset angle as the difference between the ideal position of the motor rotor and the current position of the motor rotor.
