excitation winding pole coil 励磁绕组线圈
Electric Excitation Claw-Pole synchronous Generator 为电励磁爪极发电机
Pole pieces, key parts on electrical motor, reduce the reluctance of the air-gap; improve the static magnetic field distributions and fix the excitation windings.
极靴是电机上的关键零件，其作用是使气隙磁阻减小，改善磁场分布，并使励磁绕组容易固定。
From the relations, it is concluded that pole-number selection of windings not only determines direction of 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 simulations also show that the magnetic field from the excitation windings directly influences the field distribution at the end of the quadrupole magnet if the pole neck is too short.
