转子磁场中心安装偏差所产生的轴向磁拉力很小，转子磁极中心挂装高程差所产生的不平衡力偶不致增大推力瓦受力。
The couple of force created by rotor pole center suspending difference may not increase the pressure on the thrust pad.
步进电动机象同步电动机一样，在负载转矩的作用下，转子磁极中心线将滞后于气隙磁场的中心线一个角度，称为失调角。
Like synchronous motor, rotor magnetic pole center line could lagged behind an Angle of that of air-gap magnetic field under the function of load torque (called angular displacement).
磁场产生于地球快速旋转的中心，并产生发电。” 而且磁极与地球的物理两级并不在一条直线上。
The field is generated in the Earth’s core as it spins, creating a dynamo," and the magnetic poles don’t line up with the Earth’s physical poles.
