Abstract

The image method has been used for calculating the three-dimensional magnetic field and parameters of a superconducting AC generator. The method can represent the actual shape of the coils and take account of the conductor cross-section. The influence of the magnetic and conducting boundaries are represented approximately by their images in the boundaries. The influence of either conical or stepped boundaries in the end region is represented by forming images on an adjustable conical surface in association with the boundary condition, improving the accuracy of the calculation
