Abstract
Description
この発明は、上記のような課題を解決するためになされたもので、コイルの占積率を高くするとともに短辺側のコイル高さを抑制することができる回転電機の固定子を得ることを目的とする。
前記固定子コイルは、1層目を前記ティース部に前記固定子の外径側から内径側へ順次巻き付けられるとともに、層毎に巻き付け方向を反転させて巻き付けられ、最外層をn(但し、nは3以上の奇数)、各層の最終ターンをm(但し、mは2以上)とし、1層目の1ターン目を(1,1)、1層目の2ターン目を(1,2)、2層目の1ターン目を(2,1)、2層目の2ターン目を(2,2)・・・n層目のmターン目を(n,m)としたとき、n層目のmターン目(n,m)が前記固定子の外径側に巻き付けられ、内径側の前記固定子コイルが短辺側ティース部でレーンチェンジされるとともに、外径側の前記固定子コイルの一部を長辺側ティース部でレーンチェンジされていることを特徴としている。
実施の形態1.
図1は、この発明の実施の形態1に係る回転電機の全体構造を示す要部断面図、図2は、図1における固定子の要部構成を示す断面図、図3A、図3Bは、図2におけるA、B方向から見た固定子の断面図、図4A、図4Bは、発明の実施の形態1に係る固定子コイルの1層目の巻線工程を説明するための図2におけるA、B方向から見た概略断面図、図5A、図5Bは、発明の実施の形態1に係る固定子コイルの2層目の巻線工程を説明するための図2におけるA、B方向から見た概略断面図、図6A、図6B、図7A、図7bは、図2における固定子コイルの3層目の巻線工程を説明するための図2におけるA、B方向から見た概略断面図である。
ここで、固定子鉄心4は、薄い電磁鋼板を積層してかしめや溶接により一体に組み立てられ、円筒状に形成されるとともに、固定子コイル6は、大電流が流れるため、太い径の線材で構成されている。
まず、図4A、図4Bに示すように、巻き始めターンの端末線6aを固定子鉄心4の最外径側からティース部4bへ導入し、1ターン目を固定子鉄心4の外径側(1,1)から内径側(1,9)へ順次巻き付ける。ここで、一方の短辺側ティース部4bにおいて巻線位置を内径側に移動させるレーンチェンジを行なっている。次に、図5A、図5Bに示すように、2層目の巻線を固定子鉄心4の内径側(2,1)から外径側(2,9)へ順次巻き付け、この2層目においても短辺側の一方のティース部4bにおいて巻線位置を外径側に移動させるレーンチェンジを行なっている。
さらに、3層目の2ターン目(3,2)から3ターン目(3,3)へ巻き付けるとき、固定子鉄心4の最外径側から内径側へ順次巻き付け、一方の短辺側ティース部4bでレーンチェンジを行っている。その後、図7A、図7Bに示すように、3層目の3ターン目(3,3)で最内径側からコイル2本分からなる隙間Z2の外径側に、他方の短辺側ティース部4bでレーンチェンジを行って長辺側ティース部4aへコイルを巻き付けている。
(1)奇数層となる最外層に複数ターン巻き付ける際、図3Aに示すように最外層の最終ターン(m,n)を外径側に配置することによって端末線6a、6bの引き出しを容易とすることができる。
(2)ティース部によって形成されるスロットは、台形形状であり、固定子鉄心4の内径側が狭く外径側が広くなるため、外径側にある隙間で長辺側ティース部4aのレーンチェンジを行うことにより、内径側ティース部4bの隙間が小さい位置で長辺側のレーンチェンジを行うよりも太い線径のコイル線を用いることができ、占積率の向上が可能となる。
(4)同層内のレーンチェンジに伴う交差部を一方の短辺側ティース部にのみとすることによって、回転軸2aに沿った軸方向の両端に有する場合よりも固定子コイルの軸方向高さを小さくすることができる。
(7)奇数層で最外層に複数ターン巻き付け、最外層の最終ターン(m,n)を外径側に配置する際、最終ターン付近以外のレーンチェンジを固定子コイル1本分のレーンチェンジで巻き付けるため、巻き線を単純化することができる。
(9)最外層の3層目の最終3ターン(3,3)を長辺側ティース部4aでレーンチェンジすることにより、最終3ターン(3,3)から巻き終り端末線6bを引き出す際、2層目の最終ターン(2,9)の固定子コイル上部を通過することなく最外径側から巻き終り端末線6bを引き出すことができるため、固定子コイル高さが小さくなり、回転電機の回転軸に沿った方向のサイズを小さくすることができる。
図8は、この発明の実施の形態2に係る回転電機の全体構造を示す要部断面図、図9は、図8における固定子の要部構成を示す断面図、図10Aは、図9におけるA方向から見た固定子の断面図、図10Bは、図9におけるB方向から見た固定子の断面図である。
ここで、この実施の形態2においては、1層目を全9ターン、2層目を全9ターン、最終の3層目を全3.5ターンとするものが示されている。
まず、図10A、図10Bに示すように、巻き始めターンの端末線6aを固定子鉄心4の最外径側から一方の短辺側ティース部4bへ導入し、1層目の1ターンを固定子鉄心4の外径側(1,1)から内径側(1,9)へ順次巻き付ける。ここで、この一方の短辺側ティース部4bにおいて巻線位置を内径側に移動させるレーンチェンジを行なっている。
次に、2層目の巻線を固定子鉄心4の内径側(2,1)から外径側(2,9)へ順次巻き付け、この2層目においても一方の短辺側ティース部4bにおいて巻線位置を外径側に移動させるレーンチェンジを行なっている。
さらに、3層目の2ターン目(3,2)から3ターン目(3,3)へ巻き付けるとき、固定子鉄心4の最外径側から内径側へ順次巻き付け、一方の短辺側ティース部4bでレーンチェンジを行っている。その後、3層目の3ターン目(3,3)で最内径側から固定子コイル2本分からなる隙間の外径側に、他方の短辺側ティース部4bでレーンチェンジを行って長辺側ティース部4aへ固定子コイルを巻き付けている。
また、3層目の1ターン目(3,1)から3層目の3ターン目(3,3)への巻き付けにおいては、同層内のターンで構成されたレーンチェンジに伴う交差部6cを端末線6a,6bを引出すティース部4bの反対の他方の短辺側ティース部4bにのみに形成しているため、端末線6a,6b側の固定子コイル高さは、反対側の固定子コイル高さに比べて約コイル1本分低くなることになる。
(10)最外層の3ターン(3,3)から3.5ターン(3,3.5)への巻き付けを長辺側ティース部4aでレーンチェンジすることにより、2層目の最終ターン(2,9)から最外層の1ターン(3,1)へ向かうレーンチェンジ部の上部を通過することなく、巻き付けることができ、固定子コイル高さを小さくし、回転電機の軸方向サイズを小さくすることができる。
(11)巻き始め、巻き終り端末線6a,6bを互いに反対の短辺側ティース部4bから引き出すことによって、端末線6a,6bを一方向から引き出す場合よりも固定子3の外径サイズを小さくすることができる。
(12)端末線6a,6bを互いに反対の短辺側ティース部4bから引き出すことによって、スロットが多く端末線の間隔が狭くなる場合であっても、十分に間隔を確保することができ、端末線6a,6b間の絶縁性を向上させることができる。
(13)さらに、十分に間隔を確保することができる結果、端末線6a,6bの引き出しを容易にすることができる。
また、本発明は、その発明の範囲内において、各実施の形態を適宜、変形、省略することが可能である。
