Abstract
Description
図3は、このステータ3に用いられるボビン12の三面図である。図示のように、ティースの数が少ないと、径方向の内外周に設けられるボビン12のツバ13が、回転電機の円周方向に沿った円弧形状となる。一例として、このボビン12に導体径φ1.3mm(皮膜込み外径φ1.4mm)×3本持ちの電線14を8ターン(合計24ターン)巻回させる場合、整列性を保った理想の電線配置は、図4に示す配置図である。しかし、実際には、図4のように電線14は巻き付けられない。これは、巻付け面が傾斜していることにより渡り線が干渉することに基因する(特に、ボビンの内周側のツバと渡り線との干渉の影響が大きい)。最悪の場合は、図5に示すように、電線14はボビン12の回転軸16と直交し、内周側のツバ13に接する面A−Aよりも外側に巻き付こうとする。そのため、全てのコイルのコイルエンド(ボビンの短辺)10を跨る電線14が全て面A−Aより外側を通り、コイルエンドの高さは17.1mm以上となる。また、最悪の場合は、スロット内に配置できる電線14の本数は22本となり、スロット占積率(皮膜込み導体面積の合計×100/スロット内の巻線有効空間)は、理想の電線配置の場合の54.9%に対して、45.5%に悪化する。
