摘要： The invention relates to an electronically commutated electric motor. The electronically commutated electric motor has a power output stage connected to a stator of the electric motor, and a processing unit connected to the power output stage. The processing unit is designed to drive the power output stage to produce at least one stator current. The electric motor has a current sensor which is designed to record the stator current produced by the power output stage and to generate a current signal representing the stator current. The processing unit is designed to use the current sensor to record at least one current value of the current at a recording time within an interval of time and to determine a current profile of the current in the interval of time at least on the basis of the current value and to drive the power output stage to energize the stator on the basis of the current profile determined.
