ECONOMIC DOUBLE-LAYER WINDING OF ELECTRICAL MACHINE |
摘要 |
FIELD: electricity.SUBSTANCE: in a double-layer winding of an electrical machine that includes active conductors placed in the core slots and end-coil conductors placed over end surfaces of this core, wherein the significant number of joints of ends of the end-coil and active conductors are placed near edges of the end surface of a tooth-and-slot area of the core and the above joints have the area of connection less than the square area of cross-sections averaged against the slot length of the connected active conductors of the winding, the active conductors with the reduced square area of joints are made so that the cross-section area of their ends is increased step-by-step in the direction to the slot centres, and the end-coil conductors are made so that the cross-section area of their ends is increased step-by-step in the direction to the centres of these end-coil conductors.EFFECT: improved cooling of the winding at reduced material consumption.2 dwg |
