Abstract

Rotor of a permanent-magnet machine, having a laminated rotor magnetic circuit structure containing permanent magnets (22) embedded in the rotor (21). The rotor has at least two adjacent permanent magnets (22) per pole and they are so arranged on the rotor body (21) that most of the flux produced by individual magnets crosses the air gap, thus forming the main flux of the machine, and the outer circumference of the laminated plates forms a ring (23) holding the magnets in place.
