The general can be used in electrical engineering. It has higher efficiency and reduced overall dimensions, and also supplies a low value moment of resistance. The generator includes a stator (1) in the form of an electric magnet with a first coil (2), rotor (3) in the stator (1) and two brushes. Stator (1) is cylindrical and consists of a central inner cylinder (5) with a second coil (6) in it also an outer hollow cylinder (7) in which the first coil (2) is fitted. Both cylinders (7 & 11) are of soft magnetic material and there is an air gap (8) between the external surface of the inner cylinder (5) and the internal surface of the outer cylinder (7). To each of the two composite fronts of cylinder (7 & 11) there is a respective cylindrical holder (12) with a W-shaped profile in section. The middle projection (13) of every holder (12) has diameter equal to the outer diameter of the inner cylinder (5) and between the cylindrical surface of projection (13) and the inner surfaces of the periphery of the holders (12) there are ring-like cavities (14). In one of the holders (12) there is a side hole (15) and two front holes (16) through which the supply wires of the second coil (6) pass. Rotor (3) rests in stator (1) by means of bearings (17) and is extended in cavity (14) of holder (12) by the hole (15) opposite to which on the stator (3) there is a washer (18). Opposite to every brush (4) on the rotor (3) there is one current conducting ring (19) each. In the middle of stator (1) on a magnetically neutral line there is a third brush (20) opposite to which, on the rotor (3), there is a third current conducting ring (21) between which and the two rings (19) conductors (22) are connected parallel to the axis of revilution. 1 claim, 1 figure
