大型同步电动机转子磁场中心安装偏差及转子磁极中心挂装高程差对推力瓦受力的影响
Affects of Rotor Magnetic Field Center Deflection and Rotor Pole Center Suspending Difference to the Pressure on Thrust Pad in Large Synchronous Machines
【摘要】 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。因此,不可能成为推力瓦烧损事故的原因
【Abstract】 The axial magnetic pull created by the center deflection of rotor magnetic field is very small.The couple of force created by rotor pole center suspending difference may not increase the pressure on the thrust pad.Hence it can not cause burning of the thrust pad.
