SYSTEMS, METHODS, AND APPARATUS FOR CONTROLLING KEY BAR MOVEMENT IN A STATOR ASSEMBLY

PURPOSE: A stator assembly part is provided to control the operation of a key bar by maintaining the key bar within a predetermined tolerance through a plurality of core ring compression bands. CONSTITUTION: A stator core(505) comprises a plurality of coaxially laminated laminates. A plurality of key bars(510) are arranged in a plurality of key bar grooves. A first core support ring(520a) and a second core support ring(520b) are arranged in the vicinity of the stator core. The first core support ring and the second core support ring are installed in a stator frame(525). A core ring compression band(515) is arranged in the vicinity of the stator core and the key bar.
