Title (EN) ROTOR STRUCTURE FOR OUTER-ROTOR TYPE MULTI-POLE GENERATOR
(FR) STRUCTURE DE ROTOR POUR GÉNÉRATEUR MULTIPOLAIRE DU TYPE À ROTOR EXTERNE
(JA) アウターロータ型多極発電機におけるロータ構造
Abstract:
(EN) An outer-rotor type multi-pole generator equipped with a fixed stator and a rotor that coaxially surrounds the stator and is formed in a cylindrical shape, and is provided with multiple permanent magnets on the inner circumferential surface of a yoke coupled to a drive shaft and formed from a magnetic material, wherein a hub (20) coupled to the drive shaft (14) and a cylindrical part (21) one end of which is continuous with the hub (20) are integrally formed from a nonmagnetic material, and the yoke (22A) is attached to the inner circumferential surface of the cylindrical part (21). Thus, it is possible to provide a more lightweight rotor structure for which centering of the yoke is made easier.
(FR) L'invention porte sur un générateur multipolaire du type à rotor externe, qui est équipé d'un stator fixe et d'un rotor qui entoure coaxialement le stator et qui est formé sous une forme cylindrique, et est pourvu de multiples aimants permanents sur la surface circonférentielle intérieure d'une culasse accouplée à un arbre d'entraînement et formée à partir d'un matériau magnétique. Un moyeu (20) accouplé à l'arbre d'entraînement (14) et une partie cylindrique (21) dont une extrémité est continue avec le moyeu (20) sont formés d'un seul tenant à partir d'un matériau non magnétique, et la culasse (22A) est fixée à la surface circonférentielle intérieure de la partie cylindrique (21). Il est ainsi possible d'obtenir une structure de rotor plus légère pour laquelle le centrage de la culasse est plus facile.
(JA) 固定のステータと、ステータを同軸に囲繞して円筒状に形成されるとともに駆動軸に連結される磁性材料製のヨークの内周面に複数の永久磁石が設けられるロータとを備えるアウターロータ型多極発電機において、駆動軸(14)に連結されるハブ(20)と、ハブ(20)に一端部が連なる円筒部(21)とが非磁性材料で一体に形成され、円筒部(21)の内周面にヨーク(22A)が固着される。これにより、軽量化を図りつつヨークの芯出しを容易としたロータ構造を提供することができる。
