Abstract: A d.c. motor, the armature of which comprises at least two windings in two-phase arrangement, and supplied with a direct current whose direction reverses periodically. The armature windings are series-connected through inverter circuits. This arrangement improves the efficiency of the motor and the smoothness of the torque. The motor finds a wide field of applications, in particular in space engineering field.

Abstract: A brushless D. C. motor has a stator, the windings of which are connected to a D. C. source through the medium of pairs of switches in such a manner that these windings are permanently fed and that the current is reversed in the windings at the moment when no counterelectromotive force is induced therein, this winding being at this moment put in series with at least one other winding in which the counterelectromotive force induced is not zero.
