Abstract
An internal-rotor intermediate-frequency permanent magnet generator device comprises a case, a stator connected with the case, an internal rotor arranged at the middle part of the stator, and an internal rotor connection disc connected with the internal rotor, wherein the internal rotor includes an internal rotor magnetic steel iron core, and a V-shaped magnetic steel slot for assembling the internal rotor magnetic steel iron core. The rotor is arranged in the stator; the stator iron core is designed to a split structure; one tooth corresponds to one independent lamination; each tooth is a pole; the coil of each pole is wound on the tooth individually; and the iron core of each pole of the stator is thermally sheathed on the split stator iron cores forming a complete circle through the internal circle of an aluminum alloy case with cooling fins. Accordingly, the main loss heat generated by the stator is dissipated by a fan through the cooling fins of the aluminum case; and the cooling air is suctioned by the fan from reinforcement ribs on a rotor stand, then flows to the front end of the stator, and is blown out to a ventilation network at the periphery of a pedestal by the fan, so that the cooling air flows in a folded path.
