Abstract

La présente invention concerne un rotor à aimants permanents pour moteurs synchrones, de forme extérieure sinusoïdale (14). L'emplacement et la forme en coupe des aimants permanent sont conçus pour que la densité du flux magnétique dans l'entrefer (15) entre stator (11) et rotor (12) varie de façon sensiblement sinusoïdale. En outre, ce rotor (12) comporte en zone inter-polaire des trous (22) qui, associés aux cavités des aimants (17), forment des ponts (26) supportant les sabots (23) faisant office de barrières s'opposant à la dispersion du flux magnétique d'excitation des aimants permanents (13, 19, 21a, 21b).
