SUPERCONDUCTIVE ELECTRIC MOTOR AND GENERATOR

摘要

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.

1. A superconductive electro-magnetic device for use within a direct current motor or generator that includes an armature that rotates when a rotational force is applied thereto, the armature having windings thereon, and a stator within which the armature rotates, the stator including at least two magnets and, the device comprising:
a hollow shielding sleeve located between the armature and the stator, the shielding sleeve having an inner wall and an outer wall, such that a cooling fluid can flow within the shielding sleeve; and a plurality of superconductor plates arranged singly or in pairs within the shielding sleeve and having gaps between the single plates or pairs of plates, wherein each gap is located between the armature windings and the stator magnets.
