The winding does have alot to do with how much torque she makes.

In comparing this, think about the "turn" ratings on brushed motors. The fewer turns meant you had a high speed motor. If you have many turns, then you have a low speed motor that makes more torque.

A "Race" motor in the 540 size might have as few as 4 turns. But a Lathe motor for a rock crawler might have as many as 30 turns.

Remember the "wrap the wire around the nail" experiment? How did the number of wraps affect amp draw and how strong the magnet became?
