Motor driving control apparatus, motor driving control method, and motor using the same

摘要

There are provided a motor driving control apparatus, a motor driving control method, and a motor using the same. The motor driving control apparatus includes a driving signal generation unit, a back electromotive force detection unit, and a frequency controller. The driving signal generation unit may generate a driving control signal for controlling driving of a motor device. The back electromotive force detection unit may detect back electromotive force of the motor device. The frequency controller may provide control to estimate a zero crossing point of the back electromotive force, set a frequency modulation section including the zero crossing point, and modulate a frequency of the driving control signal during the frequency modulation section.
