Japanese Patent JP7275249

B2

According to the present invention, provided is a motor of which a controller generates an index signal at a second time point delayed from a first time point at which a pulse due to an index magnet is detected among pulses of a pulse width modulation (PWM) signal detected by a second Hall sensor, compares a second time point which is input in advance based on a constant speed condition of the motor and a detected second time point to obtain a first error, compares a duty value, which is input in advance based on the constant speed condition of the motor, of a PWM signal and a duty value of a detected PWM signal to obtain a second error, and controls a speed of the motor on basis of the first error and the second error.
