or many years, DC mill auxiliary motors for steel mill applications such as screwdowns, shears, tables and sideguides were specified as "mill duty." They are of an extremely rugged design based on AIST dimensional and rating standards, and are therefore interchangeable between motor manufacturers. Many thou-sands of mill-duty motors remain ...
