The rotor is formed by two parallel shafts (1, 2) with groups of magnets (3) and a material (4) that orients the magnetic field in each group of magnets (3). The stator formed by groups of magnets (5) is close to the rotor with the shaft (6) of the stator orthogonal to each shaft (1, 2) of the rotor. The groups of magnets (3) of each shaft of the rotor are placed in attraction close behind one another on a helical line at different distances from each shaft of the rotor, the first group of magnets (3) that interacts with the stator being the group furthest from each shaft of the rotor and the final group that interacts with the stator being the group closest to each shaft of the rotor. The invention is used to assist torque, for example in a pedal of a bicycle as the main force is from human muscle.
