    摘要: A brushless DC-motor driving controller is provided which can significantly reduce torque fluctuations in the brushless DC motor. The brushless DC-motor driving controller uses a position detector, generates rotation-angle signals representing rotor-rotation angles or a part thereof in high resolution, uses the rotation-angle signals, and performs rectangular-wave driving. By using the rotation-angle signals, the brushless DC-motor driving controller compensates for electrical angles corresponding to commutation-position skews in rectangular-wave driving which are caused by armature reaction in a brushless DC-motor.

    摘要: The method serves the commutation of an electrically commutated brushless, polyphase permanent magnet motor. The commutation angle, i.e. the angle from the zero crossing of the BEMF signal up to the reapplication of the voltage to the same winding is determined by the angle which results when the winding phase current has reached zero until the zero crossing of the BEMF signal.
