In order to solve oil film whip and whirl problems about oil film bearings for high -speed frequency modula-tion motor under emergency condition,the operating principle is analyzed for controllable radial oil film bearings.The mechanical model is established for oil film bearing -elastic rotor system,and the influence of control phase and gain change on impact load is studied under emergency condition.The results show that the controllable oil film bearings can effectively reduce oil film whip and whirl.
