Title (EN) ROTOR, MOTOR, AND ELECTRIC POWER STEERING DEVICE
(FR) ROTOR, MOTEUR, ET DISPOSITIF DE DIRECTION ASSISTÉE ÉLECTRIQUE
(JA) ロータ、モータ、電動パワーステアリング装置
Abstract:
(EN) A rotor comprising: a shaft that rotates around a center shaft extending in the vertical direction; a rotor core fixed to the shaft; a plurality of first magnets provided in part of the rotor core in the axial direction and being arranged having intervals therebetween in the circumferential direction; and a plurality of second magnets provided at different positions to the first magnets in the axial direction of the rotor core and being arranged having intervals therebetween in the circumferential direction. The first magnets and the second magnets have the same magnetic flux density but mutually differing shapes.
(FR) L'invention concerne un rotor comprenant : un arbre qui tourne autour d'un arbre central s'étendant dans la direction verticale ; un noyau de rotor fixé à l'arbre ; une pluralité de premiers aimants disposés dans une partie du noyau de rotor dans la direction axiale et disposés avec des intervalles entre eux dans la direction circonférentielle ; et une pluralité de deuxièmes aimants disposés à différentes positions sur les premiers aimants dans la direction axiale du noyau de rotor et disposés avec des intervalles entre eux dans la direction circonférentielle. Les premiers aimants et les deuxièmes aimants ont la même densité de flux magnétique mais des formes mutuellement différentes.
(JA) 上下方向に沿って延びる中心軸を中心として回転するシャフトと、シャフトに固定されたロータコアと、ロータコアの軸方向の一部に設けられ、周方向に間隔をあけて配置された複数の第1のマグネットと、ロータコアの軸方向において第1のマグネットとは異なる位置に設けられ、周方向に間隔をあけて配置された複数の第2のマグネットと、を備え、第1のマグネットと第2のマグネットとは、磁束密度が同じで、形状が互いに異なる、ロータ。
