发明名称 WINDING WITH 6 - 4 REVERSAL OF POLES
摘要 FIELD: electrical engineering, development of multispeed electric motors. SUBSTANCE: in proposed winding with 6 - 4 reversal of poles coils are divided into 15 coil groups that are combined in three three-phase stars which arms are connected to leads. Number of coils in each coil group is determined in correspondence with numerical series 1K, 1K, 1K, 2K, 1K, 1K, 13, 1K, 1K, 2K, 1K, 1K, 1K, 2K, 1K, where K is integral positive number equal to Z<SB>1</SB> /18 and Z<SB>1</SB> is number of slots in stator of motor. In this case with 2p=4 coil groups with numbers determined in agreement with mentioned above series 2, 5, 9, 13, 1 are connected in opposition in first, second and third arms of first star. Coil groups with numbers 8, 11, 12, 15, 4 are placed in series opposition in first, second, third arms of second star. Coil groups with numbers 7, 10, 14, 3, 6 are placed in opposition in first, second, third arms of third star. EFFECT: diminished lack of balance of vectors of emf in parallel arms of winding by value and phase. 5 dwg
