Abstract
In a control signal transmitter for the commutating device of an electronically commutated motor, which contains at least two rotor position transmitters, particularly Hall effect generators, and an evaluation circuit which derives control signals for the commutating device from the output signals of the rotor position transmitters which determine the individual switching instants for the switching elements of the commutating device, in order to permit operation with a higher number of pulses, the evaluation circuit also includes a logic circuit to which the output signals of the rotor position transmitters are fed which circuit furnishes further control signals for the commutating device.
