Abstract
(EN)
According to an embodiment, a rotating electric machine is provided with a stator and a rotor (14) which is provided with a rotor core (24) having a plurality of magnetic poles, and a first permanent magnet (26) and a second permanent magnet (27) that are provided in each magnetic pole, the rotor (14) being disposed rotatably with respect to the stator. The first permanent magnet is formed of a fixed magnetic force magnet in which the product of a coercive force and a magnetization direction thickness is large. The second permanent magnet is formed of a variable magnetic force magnet in which the product of a coercive force and a magnetization direction thickness is smaller than that of the first permanent magnet. In each magnetic pole, the first permanent magnet is disposed on one end side of the magnetic pole with respect to the magnetic pole center axis (d), and the second permanent magnet is disposed on the other end side of the magnetic pole with respect to the magnetic pole center axis.

Selon un mode de réalisation, la présente invention concerne une machine tournante électrique pourvue d'un stator et d'un rotor (14) qui est pourvu d'un noyau de rotor (24) ayant une pluralité de pôles magnétiques, un premier aimant permanent (26) et un second aimant permanent (27) étant disposés dans chaque pôle magnétique, le rotor (14) étant disposé de manière rotative par rapport au stator. Le premier aimant permanent est constitué d'un aimant à force magnétique fixe dans lequel le produit d'une force coercitive et d'une épaisseur de direction de magnétisation est élevé. Le second aimant permanent est constitué d'un aimant à force magnétique variable dans lequel le produit d'une force coercitive et d'une épaisseur de direction de magnétisation est inférieur à celui du premier aimant permanent. Dans chaque pôle magnétique, le premier aimant permanent est disposé sur un côté d'extrémité du pôle magnétique par rapport à l'axe central du pôle magnétique (d), et le second aimant permanent est disposé sur l'autre côté d'extrémité du pôle magnétique par rapport à l'axe central du pôle magnétique.
