Abstract
A rotor (1) comprising a plurality of alternating magnetic poles formed by permanent magnets (3) distributed regularly between a circumferential portion (5) and a central portion (6) of the magnetic body (2) of the rotor and defining circumferential pole sections (7). The pole sections have a pre-determined pole pitch (Thetarho) and comprise a lobe-forming radial section (8). The lobe-forming radial section partially covers the magnets, such as to maximize a useful magnetic flux (PhiU) flowing radially through each of the pole sections and to minimize a leakage magnetic flux flowing through the circumferential portion. The pole sections can have a pre-determined pole overlap angle (Thetar) such as to maximize the useful magnetic flux (PhiU) and to minimize the leakage magnetic flux (PhiL), said overlap angle (Thetar) being a viewing angle of the lobe (8) from a point on the axis of the rotor.
