Abstract
Description
通常のコアの巻線方法では、アーチ状のヨーク部の内周部の円弧とその弦に囲まれる弓形領域に巻線する際、ノズルがヨーク部と干渉するため、ノズル先端をティース部に近づけることができず、位置精度良く巻線を配置することができない。そのため、コアに巻線導体を高い占積率で巻線するのは困難である。
そこで、上記弓形領域へ巻線導体を整列配置する方法の一つとして、ノズルを逐次傾けながら巻線する方法が開示されている(例えば、特許文献1参照)。
また、ノズルの必要な動作範囲が大きくなるため、ノズルの動作範囲の制約が分割型コアに比べて多い連結型コアや一体型コアに対して適用するのが困難である。
さらに、巻線導体を切断すること無く複数のティース部に連続して巻線する場合は、ノズル動作範囲を確保するために、複数の分割型コアをある程度離間して巻線装置にセットする必要がある。そのため、隣接する分割型コア間を渡る巻線導体が必要以上に長くなり、分割型コアを組み合わせてステータを組み立てる際に、この渡り巻線導体を位置固定する工数が追加され、製造工程及び製造コストが増大する問題がある。
上記ヨーク部の内周部の円弧とその弦で囲まれた弓形領域へ巻線する場合に、
上記コアの端面に巻線するときは、上記ノズルが上記弓形領域の弦を基準として上記ティース先端部側から上記ヨーク部側に向かって凸状の軌跡を描くように移動して上記巻線導体を巻線する工程と、
上記コアの側面に巻線するときは、上記ノズルが上記弓形領域の弦を基準として上記ヨーク部側から上記ティース先端部側に復帰した後、上記コアの側面に沿って移動して上記巻線導体を巻線する工程とを含むものである。
上記コアは、アーチ状のヨーク部と、上記ヨーク部の中央部から内周方向に向けて突設するティース部と、上記ティース部の先端に接続されているティース先端部を有し、
上記インシュレータは、上記ティース部の少なくとも端面上に位置する巻枠部と、上記ヨーク部の少なくとも端面上に位置し、その周方向両端面が上記巻枠部の端面より上記コアの端面側に位置する基部と、上記ティース先端部の少なくとも端面上に位置する巻枠先端部を有し、
上記巻線導体は、上記コア及び上記インシュレータの巻枠部の少なくとも上記弓形領域に巻線されている。
上記コアは、アーチ状のヨーク部と、上記ヨーク部の中央部から内周方向に向けて突設するティース部と、上記ティース部の先端に接続されているティース先端部を有し、
上記インシュレータは、上記ヨーク部の少なくとも端面上に位置する基部と、上記ティース部の少なくとも端面上に位置し、上記基部の内周側の円弧とその弦で囲まれた弓形領域に上記巻線導体の位置を定めるための溝を少なくとも1個設けた巻枠部と、上記ティース先端部の少なくとも端面上に位置する巻枠先端部を有し、
上記巻線導体は、上記コア及び上記インシュレータの巻枠部の少なくとも上記弓形領域に巻線されている。
図1(a)及び(b)はこの発明の実施の形態による分割型コアとインシュレータの形状を示す正面図および斜視図である。図2~図8はこの発明の実施の形態1によるコアの巻線方法を説明するための図である。
また、図1(a)において、下記で説明する巻線過程において分割型コア1の端面に巻線導体4を巻回する場合のノズル3の軌跡31を図示している。
図2~図8において、巻線導体4を供給するノズル3の移動方向を示すために、分割型コア1の中心を基点として相互に直交する3軸であるx軸、y軸、z軸方向をそれぞれ図中に示す。x軸方向は分割型コア1の外周側から内周側に向かう方向、y軸方向は分割型コア1の幅方向(周方向)、z軸方向は分割型コア1の軸長方向を示す。そして、分割型コア1の-z軸方向側の端面を第1端面、+z軸方向側の端面を第2端面とする。
-z軸方向側にあるインシュレータ2に対しても、前述同様の方法で巻線導体4を巻線する。そして、以上の工程を繰り返しながら、巻線導体4をインシュレータ2の巻枠先端部23側へ向けて整列巻線する。
また、インシュレータ2の巻枠先端部23付近まで巻線して1層目の巻線が完了した後、2層目の巻線がインシュレータ2の基部22側へ向けて開始される。そして、弓形領域14へ再び巻線する際は、1層目の巻線がインシュレータの巻線溝同様の役目をするため、上述の図2~図8の巻線方法によって、1層目同様に整列巻線を行うことが可能となる。
図9において、アーチ状のヨーク部12と、ヨーク部12の中央部から内周方向に向けて突設するティース部11と、ティース部11の先端に接続されているティース先端部13を有する分割型コア1に対して、ティース部11の端面上に位置する巻枠部21と、ヨーク部12の端面上に位置しその周方向両端面の凹部27が巻枠部21の端面よりコアの端面側に位置する基部22と、ティース先端部13の端面上に位置する巻枠先端部23を有するインシュレータ2を装着し、巻線導体4がインシュレータの弓形領域14を含めた巻枠部21の整列巻線されている。そして、このように整列巻線された複数の分割型コア1を、それぞれのヨーク部周方向端面を当接して環状に組み合わせることによりステータ100を構成する。
また、ノズルの必要動作範囲が小さいことから、連結型のコアや一体型のコアに対しても、ノズルとコアとの干渉を避けて巻線することができ、汎用性が高い。
さらに、連続巻線を行う場合、渡り線の長さを最小にできるため、組立工数を抑制することができる。
図10~図13はこの発明の実施の形態2によるコアの巻線方法を説明するための図である。実施の形態1では、インシュレータの基部側より巻線を開始したが、本実施の形態では、インシュレータの巻枠先端部側から巻線を開始する場合について説明する。なお、分割鉄心及びインシュレータの構造は実施の形態1と同様であるのでその説明は省略する。
そして、ノズル3を分割型コア1の端面及び側面に沿って周回することによって、インシュレータ2の巻枠部21に巻線導体4が巻枠先端部側から基部側に向けて巻線される。
