Axial-Field Flux Modulation Magnetic Gear and Its Electromagnetic Performance Analysis

The operation mechanism of the new axial-field flux modulation magnetic gear is presented.According to the specifications and the design of the prototype gear,its electromagnetic performance is computed with 2D transient field dual-rotating and 3D static field time-step method.In comparison with the experimental results,the feasibility and rationality of the prototype design are validated as well as the precision of the finite element analysis.
