Stator for synchronous motors having more than two poles

摘要

A stator for synchronous motors with more than two poles, comprising a plurality of sectors formed by lamination packs which are joined at their ends, forming as a whole a closed annular structure, at least one pole shoe protruding from each one of the sectors. The ends of the stator define, at each connecting region, thanks to respective facing shaped portions, at least one tab with mutually opposite undercuts, one for each end; the tabs accommodate corresponding portions of an elastic connecting element which surrounds the tab and rigidly couples the sectors.
