DC MOTOR WINDINGS COMMUTATED BY MAGNETICALLY CONTROLLABLE ELECTRONIC SWITCHES

摘要

PHD 79-114 -9- A DC motor which is commutated by magnetically controllable electronic switches in the form of integrated semiconductor circuits, which comprise 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 being controllable by the magnetic field of the rotor of the motor in such a way 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.
