| Zusammenfassung: | A brushless DC motor control system is arranged to control a command current indicative of a current to be supplied to the brushless motor on the basis of an estimated phase angle and an actual phase angle to control a current supplied to the brushless motor on the basis of an estimated phase angle and an actual phase angle, and to execute at least one of an estimated phase angle returning processing for returning the estimated phase angle and a current lowering processing for lowering a command current, when the estimated phase angle advances relative to the actual phase angle. |
