Embodiment Construction
[0018] The present invention constructs a self-adjusting five-degree-of-freedom hybrid magnetic bearing, and constructs its mathematical model according to the equivalent magnetic circuit method. Based on this mathematical model combined with the predetermined design parameter index, the structural parameters and electrical parameters of the magnetic bearing are formulated and calculated, and a magnetic bearing with excellent performance and meeting the requirements of practical applications is designed according to this formula.
[0019] Based on these structural parameters, use the finite element analysis software Ansoft to further optimize the design of the magnetic bearing structural parameters, and verify the correctness of the structural design principles and magnetic flux distribution. Finally, according to the mathematical model and each actual parameter, design the controller circuit.
[0020] A self-adjusting five-degree-of-freedom magnetic bearing, comprising an out...
