    摘要: The invention relates to a electric motor system comprising: a rotor (15) comprising different permanent magnets, a stator (10) comprising a winding (11) through which current is flowing for driving the rotor, a control unit (42) for controlling the current flowing through the winding, a first filter (43) for filtering the current flowing through the winding, a second filter (44) for filtering the current flowing through the winding, a comparator (45) for comparing the output signal from the first filter to the output signal from the second filter, wherein the control unit controls the current flowing through the winding depending on the result of the comparison of the two filtered signals.
