Abstract

Abstract

The electromagnetic structure design is the core of the design of electromagnetic bearing body for control rod drive mechanism (CRDM). In order to obtain a reasonable electromagnetic structure, a certain electromagnetic structure is selected according to different shapes of magnetic flux distribution, and used to build the analytical model and finite element model for electromagnetic analysis. Then, the working point of the electromagnetic bearing is determined by finite element simulation and analysis, and the key performance parameters, such as current stiffness and displacement stiffness, of the electromagnetic bearing are further analyzed and studied. Finally, cross verification is performed by comparison between the finite element simulation and analysis results and the analytical calculation results. The verification results show that the electromagnetic structure design of the CRDM electromagnetic bearing body is appropriate, and all performance indexes can meet the design requirements.
