Abstract
A stator and a rotor suitable for use in an electric motor or generator. The stator comprises a plurality of stator cons and a support for holding the coils around a rotor of the motor. A cylindrical sleeve is mounted radially inwardly on the support to form a barrier in use between cooling fluid passing over the coils and a rotor located within the stator. The rotor comprises a hub, a plurality of rotor segments, and a plurality of permanent magnets. The segments are arranged around the hub in a ring, with the permanent magnets disposed between the segments. A radially outwardly facing exposed surface of each magnet is spaced radially inwardly from an outer cylindrical profile defined by the segments.
