next size Gearless Mill Drive, i.e. a 42ft mill. It is a dual design approach considering, on the one hand, the experi-ences Siemens made with Gearless Mill Drive (GMD) instal-lations over the past 40 years and, on the other hand, using computerized design tools calculating the system behavior where experience does not yet exist.
