摘要： An electric machine stator comprises a core with slots for placing winding bars therein. The winding bars are locked within the slots by pairs of oppositely directed wedges. To eliminate the possibility of an axial displacement of the wedges and, as a result, a looseness of wedging the winding bars, the peripheral portions of extreme wedges adjoining the winding bars protrude outside the stator core and have cross slots with a band located therein which also surround the stator winding bars.

摘要： The disclosed arrangement for supporting stator end windings of an electric machine comprises a rigid inner ring and an outer ring, said rings being made of electrically insulating material. The inner ring is mounted coaxially with the inner bore of the stator core and supports the end portions of a stator bar winding, and the outer ring externally embraces these end portions. Both rings are mounted and secured together along the head portions of the end windings. The inner ring is attached to Z-shaped members arranged adjacent to the end portions and preventing the inner ring from axial displacement relative to the end portions. This is achieved due to the fact that a projection of each Z-shaped member, facing the end surface of the core, is positioned between winding bars at their outlet from core slots, said projection being rigidly connected with one of the brackets movably associated with a clamping plate of the core and attached to the outer ring. Thus, the proposed arrangement for supporting end windings, combined with the end windings supported thereby, makes up a rigid integral unit resistive to the action of vibrations arising during operation of an electric machine.

摘要： An electric generator includes a rotor, a stator, a frame, a core with radial channels, and a winding, the space between the frame and the external surface of the core being divided by radial partitions into an even number of sections communicating with one another in pairs. The first section in each pair communicates along the gas flow path with the gas coolers located in the frame in close proximity to the core faces and arranged to admit the gas flow into the radial channels of the core while the second section in each pair communicates along the gas flow path with the inlet depression zone of the fans installed on the rotor faces and is arranged to discharge the gas flow from the radial channels of the core to the fans whose pressure zone communicates along the gas flow path with the gas cooler inlet.

摘要： An arrangement in multiphase electrical machines in which a six-phase winding is provided with reduced maximum voltage between the terminals in the end portion. Three-phase windings are wound in opposite directions such that if one three-phase winding is wound clockwise, then the other three-phase windings is wound counterclockwise. The terminals of the three-phase windings are brought out at different sides of the stator. The winding reduces the highest possible voltage in the phase zone junction.
