摘要：The commutation method has the position of the rotor relative to the stator detected for provision of a commutation signal, the motor winding (a) supplied with a current at a preset commutation angle dependent on the commutation signal. The polarity of the winding current is determined upon provision of the commutation signal, the commutation angle altered in dependence on the winding current polarity, for obtaining a zero transition of the winding current in synchronism with the commutation signal.
