摘要
The present invention relates to a control apparatus for controlling an electronically commutated motor. The control device has a control output for connection to the control input terminal for inputting the rotor position signal, the exciting coil of the electronically commutated motor. Depending on the rotor position signal to generate a load current for moving the rotor of the electronically commutated motor, the controller outputs the load current through the control output. The control device comprises at least one semiconductor switch for switching the load current as a function of the semiconductor control signal. In this control unit, comprising a pulse generator comprises at least one of said semiconductor switch, the pulse generator is configured to generate a control signal of the pulse waveform of the load current for moving the rotor. In the present invention, the controller comprises a delta sigma converter is connected at least indirectly to the control input at the input, the delta-sigma converter, semiconductor control signal depending on the rotor position signal and is configured to generate a digital bit stream.
