Abstract

A rotor for an electric machine comprises a rotor core that defines a rotor slot having a central portion and an end portion. The end portion has a maximum width that is greater than a maximum width of the central portion immediately adjacent the end portion. A perimeter of the rotor slot at the end portion includes a plurality of segments extending between a first extremity at the maximum width of the end portion and a second extremity at the maximum width of the end portion. The plurality of segments include segments with different radii that decrease in magnitude from the center axis to the first extremity, and from the center axis to the second extremity.

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

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.

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
