Abstract：Because of the advantages of no physical contact with the rotor and controllable supportability, Active magnetic bearing (AMB) can help rotating machinery like motor run at high-speed and reduce its vibration and noise. In order to apply AMB to a moving platform like ship, this paper takes into account the nonlinear factors such as large amplitude motions and electromagnetic force, and make a analysis of the relationship between the stator and the carrier in motion. Then, Lagrange equation is used to derive the dynamics of the rotor at any inclined angle, both the electromagnetic force and the gravity load of AMB are calculated according to the relative position of the stator and the rotor. As a result, a mathematical model is established for the AMB-rotor system on the moving platform. Experiments show that the model is feasible and effective.
