Лобовые части каждой обмотки со стороны, противоположной выводам, имеют укороченный вылет, соответствующий второму, укороченному шагу обмотки со стороны выводов, причем образование первого шага по пазам статора со стороны, противоположной выводам, обеспечивается соединением стержней обмоток косой головкой. При этом фазовые группы с обеих сторон машины имеют одинаковые вылеты лобовых частей обмотки с чередующимися прямыми и косыми головками стержней. Во втором варианте шестифазная петлевая стержневая обмотка статора образована из двух трехфазных, сдвинутых друг относительно друга на 30 электрических градусов, обмоток, с расположенными у каждой обмотки выводами на противоположных сторонах статора. Одна из двух трехфазных обмоток выполнена с лобовыми частями с косыми головками как со стороны выводов, так и с противоположной стороны, а другая трехфазная обмотка выполнена с лобовыми частями с прямыми головками с обеих сторон статора, при этом длина лобовых частей обеих обмоток между собой с каждой стороны статора одинакова. Техническим результатом изобретения является уменьшение габаритов статора путем укорочения лобовых частей обмотки и повышение технологичности изготовления путем применения одного типа стержней и соответственно оснастки для его изготовления по верхнему ряду обмотки и аналогично одного типа стержней для нижнего ряда обмотки. 2 н.п. ф-лы, 6 ил.
