ABSTRACT:
A DC motor is commutated by magnetically controllable electronic switches in the form of integrated semiconductor circuits. Each switch comprises a first switching path between a first input terminal and an output terminal and a second switching path between a second input terminal and the output terminal. The two switching paths are controlled by the magnetic field of the rotor such that either the one or the other switching path is closed and that both switching paths are open in positions intermediate between these two positions.
