Abstract
A dynamoelectric rotary machine includes a stator with a stator winding and a rotor. The rotor includes an at least substantially cylindrical recess for receiving a shaft. The rotor includes a first material and a second material, wherein a region of the rotor in which a d-axis flux path of a magnetic flux lies is formed of the first material. The flux path caused by a magnetic stator field that can be generated by the stator winding, wherein a region of the rotor in which a q-axis flux path of the magnetic flux lies is formed of the second material.
