Abstract

Vector and scalar potential formulations are used together to facilitate accurate calculations of two-dimensional fields and forces in a synchronous motor. The scalar potential method employs a precomputed edge-based source field. The finite element model with a sliding surface in the air gap is implemented to obtain consistent results for the ripple force. Theoretical analysis presented in the paper and numerical results confirm the accuracy of the `ripple solution´ in the sliding surface model
