モータ12は、駆動軸18を介して可動スクロール部材21に連結されるロータ33(回転子)と、このロータ33の径方向外側にエアギャップを介して配置されるステータ34(固定子)とを有している。また、このステータ34は、コア35と、このコア35の上端部及び下端部にそれぞれ配置されたインシュレータ36、37と、後述するコイル76~84(図5及び図6参照)とを有している。インシュレータ36、37は、略同一の形状に形成されている。なお、以下では、インシュレータ36の構成について詳細に説明する。
図3は、インシュレータ36の斜視図である。図4は、インシュレータ36の上面視図である。これらの図に示すように、インシュレータ36は、径方向内側に向けて突出し、環状に配列された略半円形状の9つの内壁部38~46を有している。また、これらの内壁部38~46は、図4に示すように、それぞれが略同一の形状に形成されている。
図5は、ステータ34の斜視図である。図6は、ステータ34の上面視図である。なお、図5では、後述するリード線85の図示を省略する。図5及び図6に示すように、ステータ34は、コア35の径方向内側に向けて突出し、環状に配列された9つのティース49~57(歯部)を有している。また、このコア35の外周面には、コア35の軸方向に沿ってカットされた9つの凹部58~66と、9つの凸部67~75とが周方向に沿って交互に形成されている。
本実施形態のスクロール圧縮機1には、以下の特徴がある。
以下、本発明に係る固定子、モータ及び圧縮機の第2実施形態について説明する。この実施形態では、第1実施形態で説明した要素と同一の要素について同じ符号を付し、詳細な説明を省略する。図8は、縦置き乾燥工程を示す説明図である。
図8に示すように、この実施形態のインシュレータ136は、第1実施形態のインシュレータ36の突出部48(図7参照)に対応する突出部148のコア35と反対側の面148aにおいて、この突出部148の外側端部から離れた位置に溝148bが形成される点で、先に述べた第1実施形態と相違する。
本実施形態のスクロール圧縮機1には、以下の特徴がある。
以下、本発明に係る固定子、モータ及び圧縮機の第3実施形態について説明する。この実施形態では、第1実施形態で説明した要素と同一の要素について同じ符号を付し、詳細な説明を省略する。図9は、縦置き乾燥工程を示す説明図である。
図9に示すように、この実施形態のインシュレータ236は、第1実施形態のインシュレータ36の突出部48(図7参照)に対応する突出部248の全周にわたって、コア35の端面35aとの間に隙間248aが形成される点と、第1実施形態のインシュレータ37(図7参照)に対応するインシュレータ237がインシュレータ236と略同一の形状に形成される点で、先に述べた第1実施形態と相違する。
本実施形態のスクロール圧縮機1には、以下の特徴がある。
以下、本発明に係る固定子、モータ及び圧縮機の第4実施形態について説明する。この実施形態では、第1実施形態で説明した要素と同一の要素について同じ符号を付し、詳細な説明を省略する。図11は、図6に示したB-B線の矢視断面図であって、横置き乾燥工程を示す説明図である。
図11に示すように、この実施形態のインシュレータ336は、第1実施形態のインシュレータ36の突出部48(図7参照)に対応する突出部348の先端面348aに、径方向外側に突出した突起部348bが形成される点と、第1実施形態のインシュレータ37(図7参照)に対応するインシュレータ337がインシュレータ336と略同一の形状に形成される点で、先に述べた第1実施形態と相違する。また、この突起部348bの断面形状は、三角形状に形成され、突出部348の先端面348aの全周にわたって設けられている。なお、このような突起部348bは、インシュレータ336を成形する際に全周に形成される型合わせ部(パーティングライン)で代用可能である。
