Title:
ROTOR FOR A ROTARY ELECTRIC MACHINE AND ROTARY ELECTRIC MACHINE COMPRISING SUCH A ROTOR
Document Type and Number:
WIPO Patent Application WO/2013/079840
Kind Code:
A3
Abstract:
The invention relates to 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 (Θρ) and comprise a lobe-forming radial section (8). According to the invention, the lobe-forming radial section partially covers the magnets, such as to maximise a useful magnetic flux (ΦU) flowing radially through each of the pole sections and to minimise a leakage magnetic flux (ΦL) flowing through the circumferential portion. The pole sections can have a pre-determined pole overlap angle (Θr) such as to maximise the useful magnetic flux (ΦU) and to minimise the leakage magnetic flux (ΦL), said overlap angle (Θr) being a viewing angle of the lobe (8) from a point on the axis of the rotor.
