摘要：: <p>An electric machine (10) that includes a superconductor bearing (12) to position and levitate a magnetic rotor (18). The machine (10) also includes an armature circuit (26, 28) that is electro-magnetically coupled to the rotor (18), and an associated drive electronics (30). The machine (10) can function as a generator, or a motor to drive a load, and has an advantage of frictionless operation.</p>
