When utility softness was a concern, the super-synchronous motor was used. In other parts of the world, the wound rotor motor was preferred. In the late 1950s, when mills approached 2500 HP, the center drive mill arrangement with the enclosed geared drive using a high-speed synchronous motor became quite popular.
The pinion shaft is driven from the prime mover through vee-belts, in small mills of less than about 180 kW. For larger mills the shaft is coupled directly to the output shaft of a slow-speed synchronous motor, or to the output shaft of a motor-driven helical or double helical gear reducer.
Another solution is to use the so-called "gearless drive." A cyclo-converter reduces the power frequency and a synchronous motor is either wrapped around shell or mounted on a trunnion extension. This …
