摘要： To provide a cooling arrangement for an electric generator capable of supplying oil to a cylindrical rotor cavity in relatively large quantity in order to maintain a predetermined flow rate therethrough while providing spray oil cooling to a rotating rectifier assembly, a stationary non-rotating oil transfer tube is provided. The oil transfer tube extends from one end of a generator housing within a rotating shaft in generally coaxial relation with the one end of the tube being in communication with an oil inlet through the housing and the other end of the tube mounted within a rotating fitting in the rotating shaft. Additionally, the oil transfer tube has a radially extending orifice for spraying oil passing through the tube into the path of travel of the rectifier assembly upstream of the rotating fitting and the rotating fitting has an opening for carrying the remainder of the oil passing through the oil transfer tube into the cylindrical rotor cavity within the rotating shaft downstream of the rectifier assembly.

摘要： A high-power, high-voltage DC power supply includes a plurality of AC generators, each of which includes a rotor and one or more sets of armature windings wherein the rotors are linked together. A plurality of rectifiers are connected together in series and the armature windings are connected to the rectifiers such that each rectifier produces a fractional voltage which is combined with the fractional voltage developed by other rectifiers to develop a combined output voltage across all of the rectifiers. The armature windings are placed relative to one another such that a plurality of equally-spaced ripple peaks appear in the combined output voltage for each 360.degree. of each armature winding voltage. This in turn minimizes ripple magnitude leading to a desirable decrease in the overall power supply size and weight.

摘要： In order to improve the efficiency of electric machines, by reducing losses caused by eddy currents induced by high frequency fluxes, the outer surface of the rotor, including the rotor pole face, has a plurality of circumferential grooves. The grooves are provided in axially spaced relation along the rotor. Preferably, the method of reducing losses includes the step of forming the grooves by laser cutting, which permits the width and spacing of the grooves to be minimized so as to maximize loss reduction by increasing resistance to eddy currents.

摘要： A rotary electric machine including a housing having a stator. The stator includes an armature winding with end turns extending from opposite ends thereof. A rotor is journalled within the housing and the stator and is separated from the stator by an air gap. At least two nozzles are located within the housing, one adjacent each end of the armature, and directed at an associated set of end turns. A pair of partitions are disposed within the housing, one for each end of the armature. Each partition is located axially outwardly of the associated end turns and nozzle. A first air gap seal includes a resilient gasket sealingly engaging a corresponding one of the partitions and the tips of the adjacent end turns while a second air gap seal includes sheet-like seals interposed between layers of the end turns.
