ABSTRACT:
The rotor of an electric direct current rotating machine has at least one winding which cooperates with a stationary magnetic circuit. The winding is formed of several sections connected in series. The respective opposite ends of each section are connected to adjacent segments of a commutator associated with the winding. The sections are arranged on the rotor in such a manner that portions of different adjacent sections are disposed concurrently in the commutation zone so that currents flow through these portions in opposite directions. The invention finds application in particular to direct current motors and to motor-generators.
