Reliable performance is of primary importance when designing machines for aerospace applications. In the case of generators, it forces thermal, electrical and physical isolation of phases and imposes a limit on short circuit current. Single tooth high inductance permanent magnet machines suit the application and have been in use for many years. However, the small slot clearance forces the use of labour intensive manual winding techniques. In this paper, we present the redesign of an aerospace permanent magnet alternator to a segmented stator design, including alternative topology options, design procedure and results. Segmentation is shown to improve the production process and improve copper fill factor but in the first prototype appears to adversely affect material properties.
