A non-traditional topology of a superconductive electric motor or generator increases the air gap flux density by reducing stray flux and concentrating lines of flux within the air gap. An electric motor or generator utilizing the invention will include three components: a rotating armature, a permanent magnet stator and a shielding sleeve. The shielding sleeve of the motor is a hollow cylinder that fits between the armature and the stator, and is configured to cool a plurality of high-temperature superconductors within it to a temperature below their critical temperatures. These superconductors are placed at an optimized position to redirect flux and promote greater efficiency.
