Abstract: front page image
(EN)The purpose of the present invention is to reduce deformation in neighbouring divided-core contact portions during shrink fitting. Provided is a stator for a rotational electric machine provided with a stator core (232) configured from a first stator core (232A) and second stator cores (232B, 232C). The first stator core (232A) is provided with a core back which is divided in a peripheral direction. The second stator cores (232B, 232C) are provided with core backs which are integrally configured in the peripheral direction. The first stator core (232A) and the second stator cores (232B, 232C) are stacked in an axial direction.
(FR)La présente invention a pour objectif de limiter les déformations dans des parties de contact voisines d'un noyau divisé pendant l'ajustement fretté, et concerne un stator pour machine électrique tournante pourvu d'un noyau de stator (232) configuré à partir d'un premier noyau de stator (232A) et de seconds noyaux de stator (232B, 232C). Le premier noyau de stator (232A) est pourvu d'une partie arrière de noyau qui est divisée dans le sens périphérique. Les seconds noyaux de stator (232B, 232C) sont pourvus de parties arrière de stator qui sont configurées d'un seul tenant dans le sens périphérique. Le premier noyau de stator (232A) et les seconds noyaux de stator (232B, 232C) sont empilés dans le sens axial.
(JA) 焼き嵌めの際、隣接する分割コア同士の接触部における変形を低減する。 第1のステータコア232Aと第2のステータコア232B,232Cとにより構成されたステータコア232を備える回転電機において、第1のステータコア232Aは周方向に分割されたコアバックを有し、第2のステータコア232B,232Cは周方向に一体に構成されたコアバックを有し、第1のステータコア232Aと、第2のステータコア232B,232Cとが軸方向に積層されている回転電機のステータ。
