<p>A permanent magnet electric machine (i.e.: motor/generator) having a magneti c flux circuit including a stator and a permanent magnet rotor mounted for rotation about an axis relative to the stator. The stator is of material having a Curie temperature, wherein magnetic flux circulation through the stator material is impeded when the stator material acquires a temperature above the Curie temperature. The stator includes heat conducting layers and magnetic flux conducting layers, where the thermal conductivity of the heat conducting layers is greater than the thermal conductivity of the magnetic flux conducting layers. Means for quickly effecting shutdown of the electric machine are provided with a heat exchanger thermally coupled to the stator, thereby regulating magnetic flux circulation through the stator material.</S DOAB></p> |
