System and method for smoothing a salient rotor in electrical machines

Patent Raminosoa, Tsarafidy; Alexander, James Pellegrino; El-Refaie, Ayman Mohamed Fawzi; ...

An electrical machine exhibiting reduced friction and windage losses is disclosed. The electrical machine includes a stator and a rotor assembly configured to rotate relative to the stator, wherein the rotor assembly comprises a rotor core including a plurality of salient rotor poles that are spaced apart from one another around an inner hub such that an interpolar gap is formed between each adjacent pair of salient rotor poles, with an opening being defined by the rotor core in each interpolar gap. Electrically non-conductive and non-magnetic inserts are positioned in the gaps formed between the salient rotor poles, with eachmore »« less

Rotor apparatus for high strength undiffused brushless electric machine

Patent Hsu, John S [Oak Ridge, TN]

A radial gap brushless electric machine (30) having a stator (31) and a rotor (32) and a main air gap (34) also has at least one stationary excitation coil (35a, 36a) separated from the rotor (32) by a secondary air gap (35e, 35f, 36e, 36f) so as to induce a secondary flux in the rotor (32) which controls a resultant flux in the main air gap (34). Permanent magnetic (PM) material (38) is disposed in spaces between the rotor pole portions (39) to inhibit the second flux from leaking from the pole portions (39) prior to reaching the main airmore »« less

Superconducting electrical machine with rotor and stator having separate cryostats

Patent Morrison, Darrell; Daly, Ted

A superconducting electrical machine includes a rotor and a stator. The rotor includes rotor windings configured to superconduct when cooled in a rotor cryostat to a temperature no greater than a rotor superconducting temperature. The stator includes a stator windings configured to superconduct when cooled in a stator cryostat to a temperature no greater than a stator superconducting temperature. The rotor cryostat surrounds the rotor and is configured to allow transport of a first coolant through a plurality of conduits adjacent to the rotor windings in order to draw heat from the rotor windings and reduce the temperature of themore »« less

Superconducting electrical machine with two part rotor with center shaft capable of handling bending loads

Patent Morrison, Darrell

A superconducting electrical machine includes a rotor and a stator. The stator defines a cavity. The rotor is configured to rotate about a longitudinal axis. The rotor is disposed at least partially within the cavity. The rotor includes a shaft configured to rotate with the rotor, a rotor active section including at least a rotor torque tube and a superconductor, and a first re-entrant end attaching the shaft to the rotor active section. At most a threshold fraction of a bending force applied to the shaft is communicated to the rotor active section.

Permanent-magnet-less synchronous reluctance system

Patent Hsu, John S

A permanent magnet-less synchronous system includes a stator that generates a magnetic revolving field when sourced by an alternating current. An uncluttered rotor is disposed within the magnetic revolving field and spaced apart from the stator to form an air gap relative to an axis of rotation. The rotor includes a plurality of rotor pole stacks having an inner periphery biased by single polarity of a north-pole field and a south-pole field, respectively. The outer periphery of each of the rotor pole stacks are biased by an alternating polarity.
