Abstract:
1. A brushless motor control device, comprising: a brushless motor including a rotor magnet and a stator coil; rotor position detection means for detecting positions of a plurality of magnetic poles of the rotor magnet; vibration detection means for detecting an unnecessary vibration of the brushless motor when the brushless motor is rotating and providing a first output indicative of the detected vibration; lead angle setting means for setting a magnitude of a lead angle via a second output such that the first output from the vibration detection means does not exceed a prescribed tolerable value; and lead angle correction means for providing the lead angle to a third output, wherein the third output is based on the detected positions of the magnetic poles as determined by the rotor position detection means, in accordance with the second output from the lead angle setting means, so as to generate a translocation timing of a driving current to the stator coil.
