摘要： The invention relates to a method for the commutation of a brushless direct current motor having at least one motor winding in which the position of the rotor with respect to. the stator. is determined and a commutation signal is generated from this, and the motor winding is energized by a preset commutation angle as a function of the commutation signal: Depending on the construction and energization of the motor, the invention provides that the polarity of the winding, current is registered when a commutation signal appears, and the commutation 10angle is changed as a function of the recorded polarity of the winding current in such a way that the winding current is essentially zero or has a zero point when a commutation signal, appears, or, that when a commutation signal appears, the absolute value of the winding currents is measured and the commutation angle is changed as a function of the polarity of the winding current in such a way that the total excitation of the momentary phase calculated from the winding currents is essentially zero when a commutation signal appears.

摘要： A method for the commutation of a brushless direct current motor having at least one motor winding in which the position of the rotor with respect to the stator is determined, a commutation signal is generated from the position, and the motor winding is energized by a preset commutation angle as a function of the commutation signal. Depending on the construction and energization of the motor, either (i) the polarity of the winding current is registered when a commutation signal appears and the commutation angle is changed as a function of the recorded polarity of the winding current in such a way that the winding current is essentially zero or has a zero point when a commutation signal appears, or (ii) the absolute value of the winding currents is measured and the commutation angle is changed as a function of the absolute value of the winding currents in such a way that the total excitation of the momentary phase calculated from the winding currents is essentially zero when a commutation signal appears.
