DETAILED DESCRIPTION OF THE INVENTION

[0031] The dual control system of a rotor of a permanent magnet generator (1) comprises a first fixed ring of permanent magnets (3) and a second fixed ring of permanent magnets (4) which are fixed to a rotor shaft (2) such that the first fixed ring of permanent magnets (3) is fixed at one end of the rotor shaft (2) and the second fixed ring of permanent magnets (4) is fixed at the opposite end of the rotor shaft (2).

[0032] The dual control system of a rotor of a permanent magnet generator (1) also comprises a first movable ring of permanent magnets (7) and a second movable ring of permanent magnets (8) such that the movable rings of permanent magnets (7, 8) are joined to a guide axis (6) on which they are moved, the cited guide axis (6) in turn is joined to the stator (5) of the generator (1).

[0033] All the rings of magnets (3, 4, 7, 8) comprise housings (10) in which the magnets (11) are situated.

[0034] The first movable ring of permanent magnets (7) is situated on the same side of the generator (1) on which the first fixed ring of permanent magnets (3) is located and the second movable ring of permanent magnets (8) is situated on the same side of the generator on which the second fixed ring of permanent magnets (4) is located.

[0035] The rotation of the rotor shaft (2) is produced by the repulsion of the magnetic field between magnets with equal sign and therefore it is produced approximating and/or distancing the two movable rings of permanent magnets (7, 8) to the fixed rings of permanent magnets (3, 4).

[0036] The system object of the invention comprises a regulation selector (9) which in the preferred embodiment of the invention is a manual cam which approximates or distances the movable rings of permanent magnets (7, 8) according to the required angle such that the relative position of the movable rings of permanent magnets (7, 8) can be modified with respect to the fixed rings of permanent magnets (3, 4), that is to say, the movable rings of permanent magnets (7, 8) can be approximated to or distanced from the fixed rings of permanent magnets (3, 4).

[0037] Both the first fixed ring of permanent magnets (3), the second fixed ring of permanent magnets (4), the first movable ring of permanent magnets (7) and the second movable ring of permanent magnets (8) comprise a series of housings (10) where the magnets (11) are situated.

[0038] To improve the efficiency in the control of the rotation of the rotor, the magnets (11) are curved and are placed facing and inclined at an angle of between 23.5 and 25.5, using the same polarity within the housings (10) of each ring (3, 4, 7, 8) such that they do not perpendicularly contact each other to maintain the opposition of the same magnetic field.

[0039] The generator (1) is joined to a support (12) such that the support (12) enables the joining with a structure (13) where the generator (1) can be situated.
