摘要：在一馬達或發電機的轉子中，以同時增能兩個相位繞組而轉子維持固定的方式來設置一旋轉磁力線向量，其中每一相位繞組可以用相同或是不同的激發電壓來增能。分別的分接頭電壓便在此第一磁力線位置被記錄下來。之後，此兩個相位繞組被另一個激發電壓同時增能，其中每一個相位以相同或是不同的電壓增能，致使一新磁力線位置產生。再一次將分別的分接頭電壓記錄下來。此步驟可以對不同的馬達磁力線的旋轉一直重複。量測的分接頭電壓被評鑑來決定轉子位置，而不需要實際地移動之。本發明可應用於交換磁阻(SR)與非交換磁阻(non-SR)電機，其有數個相位與極心配置。

摘要： A drive system powers a six-phase AC induction motor having a plurality of poles and a stator with a plurality of teeth where the number of teeth divided by six times the number of poles equals an integer number. The stator core has first and second groups of three-phase stator windings. The second group of three-phase windings is separated spatially by 30 electrical degrees from the first group. A first power supply is connectable to the first group of three-phase windings. A second power supply is connectable to the second group of three-phase windings. The second power supply provides power to the second group of three-phase windings that is shifted by 30 electrical degrees in time with respect to the first power supply. The first and second power supplies receive signals from identical pulse width modulator generators. The respective first and second pulse width modulator generators receive commands from one controller.

摘要： A coupling transmits torque between two shafts approximately aligned on a shaft axis. The coupling has a center axis approximately aligned with the shaft axis. The coupling comprises arcuate coupling segments with ends extending generally parallel to the coupling center axis and arcuate portions extending between the ends. The arcuate coupling segments are arranged in a ring with adjacent segments being arranged end to end to form the coupling. Each coupling portion comprises a first clamp ring adapted to be operatively attached to a shaft and a second clamp ring adapted to be operatively connected to another shaft. Elastomer material extends between both clamp rings. The elastomer material extends axially and circumferentially on each clamp ring in areas adjacent to each end of the arcuate coupling segment.

摘要： An electro-dynamic machine has a rotor and stator with a gap therebetween. The machine has a frame defining a hollow interior with end cavities on axially opposite ends of the frame. A gas circulating system has an inlet that supplies high pressure gas to the frame interior and an outlet to collect gas passing therethrough. A liquid coolant circulating system has an inlet that supplies coolant to the frame interior and an outlet that collects coolant passing therethrough. The coolant inlet and gas inlet are generally located on the frame in a manner to allow coolant from the coolant inlet to flow with gas from the gas inlet to the gap. The coolant outlet and gas outlet are generally located on the frame in a manner to allow the coolant to be separated from the gas with the separated coolant and gas collected for circulation through their respective circulating systems.

摘要： An electric machine has a stator that comprises a plurality of laminations with teeth and cooling apertures about a central opening. When the laminations are stacked to form the stator core, the teeth of adjacent laminations cooperate to form slots disposed circumferentially about the central opening that are configured to receive a plurality of stator windings, and the cooling apertures angularly spaced about the central opening cooperate to form cooling manifolds that extend along a length of the stator core. A portion of the laminations has their cooling apertures offset from other laminations in the stack in a manner to create a plurality of flow paths transverse to the manifolds. The transverse flow paths extend angularly between laminations and adjacent manifolds. A header assembly directs flow into and out of the stator core.

摘要： A rotor comprises laminations with a plurality of rotor bar slots with an asymmetric arrangement about the rotor. The laminations also have magnet slots equiangularly spaced about the rotor. The magnet slots extend near to the rotor outer diameter and have permanent magnets disposed therein creating magnetic poles. The magnet slots may be formed longer than the permanent magnets disposed therein and define one or more magnet slot apertures. The permanent magnets define a number of poles and a pole pitch. The rotor bar slots are spaced from adjacent magnet slots by a distance that is at least 4% of the pole pitch. Conductive material is disposed in the rotor bar slots, and in some embodiments, may be disposed in the magnet slot apertures.

The main portion (22) defines the smallest diameter of the bearing cage and is less than the roller pitch diameter (D4). The outward flange portion may also include an outward flange guide surface for guiding barrel-shaped rollers. The guide surface is cylindrical in shape and adjacent each pocket. The guide surface is adapted to abut an axial end of the rollers.
