Abstract:
A stator for a power generator, the stator comprising:a plurality of laminations having a plurality of spaced-apart stator coil slots formed therein; stator coil slot contents positioned in each of the plurality of stator coil slots, said stator coil slot contents including at least one stator coil; a coil support finger plate positioned at an end portion of the plurality of stator coil slots, the coil support finger plate having a base and a plurality of fingers extending outwardly from the base between the plurality of spaced-apart stator coil slots, the base including a stator slot contents support portion positioned to underlie end portions of the stator slot contents and to support the end portions of the stator coil slot contents thereon so that the stator slot contents support portion defines a stator slot bottom at the coil support finger plate; wherein the plurality of fingers includes a plurality of spaced-apart pairs of fingers, wherein the stator coil slot bottom is positioned between each of the plurality of spaced-apart pairs of fingers, and wherein at least a pair of fingers of the plurality of fingers of the coil support finger plate each extend outwardly between an adjacent pair of end portions of the plurality of spaced-apart stator coil slots the at least a pair of fingers including first and second fingers, distal end portions of the first finger extending outwardly a greater distance from the base than the second finger; wherein the first and second fingers are spaced-apart from each other and the greater-distance extending distal end portions of first finger being positioned adjacent distal side peripheries of each of the adjacent pair of end portions of stator coil slots and spaced-apart from distal end portions of the second finger, wherein medial portions of the first finger extends along only side peripheries of one of the end portions of the pair of stator coil slots, and wherein the second finger extends along only side peripheries of another one of the end portions of the pair of stator coil slots; and wherein the distal end portions of the first finger has a first wedge land formed in a region thereof adjacent the one of the end portions of the pair of stator slot coils, and wherein the spaced-apart region between the distal end portions of the second finger and the distal end portions of the first finger define a second wedge land for the another one of the end portions of the pair of stator coil slots so that the first wedge land for the end portion of the one stator slot is formed by a first pair of fingers having first and second fingers thereof and the second wedge land for the end portion of the one stator slot is formed by a second pair of fingers having first and second fingers thereof.
