Permanent-magnet AC machines are becoming increasingly significant for drive systems. The authors describe a configuration of a high-field machine capable of working at leading or lagging power factor. The working gap density is very high in proportion to the volume of magnet used. Software has been written which can be used in the assessment of the relative outputs of virtually any realistic design. Comparison with test results is seen to be good for the high-field configuration tested.
