Description
I=0.5・m・r2、又は(mで割って):I/m=0.5・r2
によって与えられ、ここで、rはその半径であり、mはその質量である。モータのトルクを与えるロータの磁気モーメントは、ロータの体積に比例しており、それ故に、その質量にも比例している。方程式は、ロータ・サイズが増加されると(これはその半径を増加させることを意味する)、慣性モーメントがモータのトルクを与えるロータの磁気モーメントよりも急速に増大することを明らかに示す。ロータ・サイズを増加させることは、したがって必然的により遅いモータに至り、トルクのゲインの効果を打ち消す。
- 電流パルスが誤った極性(ロータの休止位置に関して)であれば、パルスが止まるときに、ロータは小さい振動運動を示してその休止位置に後退するであろう。
- 電流パルスが正しい極性であるが、短すぎるか又は小さすぎれば、モータに供給されるエネルギーは、モータ・ステップをするには不十分である。そのような状況では、ロータは正しい方向に運動するが、その元の休止位置に後退するであろう。
- 電流パルスが正しい極性及び持続時間であれば、ロータは、正しくそのステップをして、180°の休止位置に至るであろう。
- パルスが正しい極性であり、長すぎれば、ロータは正しく旋回してそのステップをするであろうが、パルスが持続する間は180°の休止位置を僅かに超える位置に保持され、パルスが止まるときにその正しい休止位置に後退するであろう。この場合、モータはその正しいステップをするが、しかしながらこのステップには電流パルスが持続するのと同じ時間を必要とする。
したがって、誤った電気駆動パルスでさえ、ラベット・モータは専ら正しいステップをして停止できる。逆行は、このモータ設計では可能でない。
