A control device for controlling an electronically commutated motor. The control device includes a control input for a rotor position signal and a control output for connection to field coils of the motor, and generates a load current for displacing a rotor of the motor depending on the rotor position signal outputting said load current via the control output. The control device includes at least one semiconductor switch for switching the load current depending on a semiconductor control signal, and includes at least one pulse generator which generates the load current in the form of a pulsed control signal for displacing the rotor. The control device also includes a delta sigma converter which is at least indirectly connected to the control input on the input side and which is designed to produce the semiconductor control signal in the form of a digital bit stream depending on the rotor position signal. |
