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。
Also, MMF of the field winding is represented as electric currents in the gap between poles, with regard to magnitude and direction of magnetic field at respective poles.
事实上，N极边和s极边由相同的励磁绕组励磁，这意味着模型中的磁动势只是实际磁动势的一半。
In fact, however, the N-pole side and the S-pole side are excited through the same field winding, which means that this model shows MMF that is only half the actual value.
