The result is the design of a Gearless Mill Drive motor for a 42ft Grinding Mill providing up to 35MW of power. Evolution is still the main GMD design philosophy, but realistic and proven computer models help to look beyond experience, where testing is impossible. The Siemens 42ft gearless mill drive, still an evolutionary design approach?
