Description
− ロータ1の第1の外径D1の増大は、ロータ1により生み出される磁束の増大をもたらし(これにより、図3に示されるように、モータ1,11のKeの増大をもたらす)、ひいては、トルクを生み出すために必要なステータ電流の減少をもたらす。
− ステータ巻線14のインダクタンスを増大させないように一定の回転数を維持しつつ、ロータ1の第1の外径D1が増大されると(モータ1,11のインダクタンスに対するロータ1の第1の外径D1の増大の影響のみが考慮に入れられる)、切り欠き12の表面積が更に小さくなる(切り欠き12の一定の充填レベルは維持される)ため、配線の断面が減少されなければならない。したがって、この場合には、図4に示されるようにステータ抵抗RSが増大する。
