Abstract
A direct current motor comprising a permanent magnet rotor, at least two stator windings or pairs of stator windings, and an electronic switching device having the same number of Hall elements powered by a direct current voltage and exposed to the rotor field, the output terminals of said elements being connected to the base electrodes of the transistors, so that the current through the various stator windings is controlled depending on the position of the rotor, characterized in that the transistors they form at least a group of at least two transistors, the emitters of which are fed by a common source of substantially constant current, so that, in any rotor position, only one transistor of each group can be completely driving, and each winding can be fully excited at an angle of at most 120º relative to The bipolar rotor, in a given direction.
