Abstract
A rotor includes a shaft. A plurality of rotor modules are disposed about the shaft. Each of the rotor modules includes a cylindrical support ring, a ferromagnetic core radially outward of the support ring, at least one PM arc arranged in a first ring and at least one PM arc arranged in a second ring, the first and second ring being radially outward of the ferromagnetic core, and a retainer having a first wall disposed radially outward of the first ring and the second ring and a second wall defining an axial boundary between the first ring and the second ring.
Claims22
A rotor comprising:
- a shaft;
- a plurality of rotor modules disposed about said shaft, each of said rotor modules comprising:
- a cylindrical support ring;
- a ferromagnetic core radially outward of the support ring;
- a first permanent magnet (PM) ring including a first at least one PM arc and a second PM ring including a second at least one PM arc, the first PM ring and the second PM ring being radially outward of the ferromagnetic core;
- and
- a retainer having a first wall disposed radially outward of the first PM ring and the second PM ring and a second wall defining an axial boundary between the first PM ring and the second PM ring.
