Abstract
An improved stator core and process for manufacturing the core are accomplished by a modular stator core design. The stator core is comprised of a series of equally sized and shaped stator core modules that are manufactured via a vacuum pressure impregnation process. The prefabricated modules can then be assembled into a stator core in an efficient way, saving several days of stator core assembly time. Moreover, a variety of stator core lengths can be accommodated by only inserting the required number of modules into the stator frame.
