Also, MMF of the field winding is represented as electric currents in the gap between poles, with regard to magnitude and directionof magnetic field at respective poles.
另外，用两极之间的电流表示励磁绕组磁动势，对应于各极之间磁场的大小和方向。

From the relations, it is concluded that pole-number selection of windings not only determines directionof electrical energy transfer for levitation force winding, but also does its excitation modes.
从中可以看出绕组极数选取方案决定悬浮力绕组的电能传递方向及它的励磁方式。

The thickness of the head part is changing along its warp direction and the winding Angle of any point on it varies.
