Abstract :
Though full three-dimensional (3-D) analysis is the proper method to analyze the hybrid stepping motor (HSM), it has weaknesses in the computation time and complexity. This paper introduces a two-dimensional (2-D) finite-element analysis (FEA) using a virtual magnetic barrier for the axial cross section to save computation time. For the purpose of 2-D FEA, the virtual magnetic barrier and equivalent permanent magnet model of HSM are proposed. This result is compared with that of experimental and 3-D analysis, considered as reference result.
