Characteristics analysis of axial flux type reluctance motor using 2 and 3-dimensional finite element method

The paper proposes static and dynamic characteristics analysis algorithms for the axial flux type reluctance motor (AFSRM) considering the nonlinear magnetic phenomena. To investigate the nonlinearity parameters of magnetic equivalent circuit, the designed 4-phase AFSRM is analyzed by the 2D and 3D finite element method as functions of input current and angular displacement. Field solutions from finite element analysis are processed to give the energy conversion loop and the flux linkage curve as functions of input current. The output performance of AFSRM was calculated using FEM analysis, the current, torque, back EMF and output power wave of AFSRM are simulated from the motion equation by MATLAB/SIMULINK. The simulated characteristics for 4-phases, 24-poles TSRM are verified by experiments on a prototype motor.
