Abstract
A segmented electric generator/motor, such as for a wind powered generator, in which the rotor and/or stator is subdivided in the circumferential direction into segments disposed adjacent to one another. Additionally, the stator segments are accessible via and the rotor segments can be installed and removed in the axial direction in rotor segment mounts provided in the rotor ring. Each rotor segment preferably includes a base shaped to prevent radial and circumferential or tangential motion of the rotor segment while permitting axial motion in the rotor segment's respective mount. The rotor ring segment mounts are preferably sized to allow removal of stator segments through the openings.
