VERFAHREN UND ANORDNUNG ZUR KOMMUTIERUNG EINES ELEKTRONISCH KOMMUTIERTEN MOTORS

摘要

The method involves determining a value of a current of an electronically commutated motor (120), after a change of rotor position signals, which are assigned to a pole change. A new commutation is executed after expiration of a preset time period after the pole change. Another value for the current is determined after a change of the signals, which take place on the new commutation. The value for the time period is changed based on the difference between the two values of the motor current to cause adjustment of the values for the motor current during an application of the changed value. An independent claim is also included for an electronically commutated motor with a permanent magnetic rotor.
