【Abstract】 The article narrates the superiority of the magnetic suspended bearing and the rotating axis with much supporting adopting the magnetic suspended bearing.Put forward the univeral count method,that is ulitizing the three curved momental equation earlier obtained the surplus supporting opposite force of rotating axis with much supporting also no defined calm,after again counting out ferst critical rotating velocity.It solves the difficulty question of the counting ferst critical rotating velocity for rotating axis with much supporting, possessing specified practical value.更多还原
