摘要： The invention relates to a method for controlling operation of an electric motor (1), wherein electrical voltages applied to electrical phases of the electric motor (1) are produced and output in a controlled manner in a modulation on the basis of a rotor position of the electric motor (1), on the basis of a setpoint/actual comparison, which is performed in a control loop with a speed controller (5), for a speed of the electric motor (1) and on the basis of a setpoint/actual comparison, which is performed in a current regulator (6) underlying the speed controller (5), for a summed current (I
DC_actual ) measured on an electric power supply unit of the electric motor (1), wherein a setpoint value (I
DC ) at the input of the current regulator is formed by multiplying a present duty factor (T) for the modulation by a first manipulated variable (I
AC ) applied to the output of the speed controller (5), wherein the first manipulated variable (I
AC ) of the speed controller (5) becomes an equivalent phase current RMS value for the electric motor (1) in the underlying current regulator (6) by means of the multiplication by the present duty factor (T). The invention additionally relates to an apparatus for controlling operation of an electric motor (1).摘要翻译： 本发明涉及一种用于控制电动机（1）的操作的方法，其中施加到电动机（1）的电相的电压基于电动机 基于在具有速度控制器（5）的控制回路中执行的设定点/实际比较，针对电动机（1）的速度并且基于设定点/实际比较来确定电动机（1） （1）的电力供应单元上测得的总电流（IDC_实际值），其中在电流调节器（5）下面的电流调节器（6）中执行实际比较，其中设定值（IDC） 在所述电流调节器的所述输入处通过将用于所述调制的当前占空因数（T）乘以施加于所述速度控制器（5）的所述输出的第一操纵变量（IAC）而形成，其中所述第一操纵变量（IAC）为 速度控制器（5）变成等效的 通过乘以当前的占空因数（T）来调节基础电流调节器（6）中的电动机（1）的三相电流RMS值。 本发明还涉及用于控制电动机（1）的操作的设备。
