Electric machine

An electric machine comprising:

• at least one stator (2) with windings;
• a first rotor (3) and a second rotor (4) with permanent magnets, which are mounted with the ability of mutual rotation relative to each other and relative to a mechanical power transmission link (14) by a limited adjustable angle, wherein the number of mentioned pairs of rotors (3, 4) is equal to the number of stators (2);
• at least one differential comprising at least one planet pinion (5) mounted with the ability to determine mutual rotation of the first and the second rotors (3, 4);
• a first and a second sun gears (6, 7) fixedly mounted on the first and the second rotors (3, 4), each sun gear being mechanically connected to each planet pinion (5);
• a magnetic flux regulator with at least one nonmoving part (8, 9) and with at least one moving part (10) mechanically connected to each planet pinion (5) and configured to contactlessly interact with the nonmoving part (8, 9) of the magnetic flux regulator;
• the mechanical power transmission link (14) fixedly coupled to the at least one moving part (10) of the magnetic flux regulator;
• and a control system associated with the nonmoving part (8, 9) of the magnetic flux regulator and with the stator (2),
• characterized in that it comprises an auxiliary rotor (13) fixedly connected to the mechanical power transmission link (14),
• wherein the first rotor (3) and the second rotor (4) are mounted with an axial distance therebetween, wherein the first rotor (3) and the second rotor (4) are mounted between the inner or outer perimeter of the stator (2) and the outer or inner perimeter of the auxiliary rotor (13) with radial gaps, and wherein the stator (2) and the auxiliary rotor (13) have the same axial size, and the sum of the axial lengths of the first and the second rotors (3, 4) and the axial distance therebetween is equal to the axial length of the auxiliary rotor (13).
