Abstract:
The excitation system of the homopolar inductor machine(HIM)is analyzed and designed to establish the design approach and evaluation criteria of the excitation system. The finite element method is used to calculate the three-dimensional electromagnetic field in the HIM, and the distribution and characteristics of the magnetic field are described. The analytical method is applied to investigate the design process of the excitation winding. The ratio of the axial length of the armature winding to the excitation winding and the ratio of the axial length of the working air-gap to the non-working air-gap are investigated by the numerical calculation method. A prototype HIM is designed and manufactured, and some experiments are implemented to verify the correctness of the theoretical analysis and numerical calculation results. The research results show that the established design method of the excitation winding is practical and feasible. Under the conditions of constant excitation magnetomotive force or constant excitation power, the optimum range of the axial length ratio of the armature winding and the excitation winding is 0.45 to 0.5. The optimal axial length of the non-working air-gap can be determined by the ratio of the stator inner diameter and pole-pairs.
