Abstract
【解決手段】モータ10は、ステータ100と、ロータ200を有し、ブラシレスモータであり、磁束集中型ロータ200を有し、そのステータ100は歯部上に巻線を有し、三相交流で動作する。ステータ100は、鋼製ケース110を有する。このケースは、ステータの巻線に電力を供給するために、電気導線が通過する側部開口部111を有する。ケースの外側には、固定タブ112と、持ち上げ用のフック113を有する。
【選択図】図1
Description
(a) 上記ハウジングは、上記磁石を受けるために、磁極部の間に形成されている。
(b) 磁極部は、ロータが所定速度以上の速度で回転すると、遠心力により上記ハウジングが拡大し、その拡大は回転速度の減少により消滅するように、配置されている。
(c) 上記磁石は、ロータが所定速度以上の速度で回転するときに拡大するハウジングによって形成されたギャップに係合して配置されており、ロータの速度が上記予め決められた速度以下に低下したときに、上記磁石に上記磁極部を締め付ける(クランプする)。上記磁極部は、シャフトのスプライン上に配置してもよいし、シャフトに固定した棒に取り付けてもよい。
特にコンパクトは構成により、シャフトの端部に張り出し状態で取り付けることができる。そのため、ベアリングの数が減少し、摩擦による機械的損失が減少し、潤滑の問題が減少する。
磁石は表面に誘導される電流に殆ど曝されることがないので、マグネットが分離したり過熱したりすることなく、ロータは高速で回転できる。
個々のコイルは、容易に据え付け及び交換ができる。また、ステータを再含浸させる必要がない。
磁石の質量は非常に小さく、分割する必要がない。
歯部の数及びコイルの数は比較的小さく、そのために製造が容易である。
コイルのヘッド部は非常に短く、そのために軸方向に小型の構造が得られる。
位相は接点無しに又は渡り線(クロスオーバ)無しで、電気的に分離できる。
コイルの巻きは接触させることができるので、スロットが十分に満たされる。
トルクリップルは、無視できる。
