Insurability of Large Gearless Mill Drives (GMDs)

2014-9-28  Introduction. We have written on risk associated with large ring motors in gearless mill drives previously [1, 2, 3]. In [1], we observed that ABB and Polysius were far too confident in 2001 when they claimed that 42 and 44 ft diameter mills and ring motors posed only manageable risks and that a 44 ft mill and GMD design was ready and waiting for a purchaser [4].

Literature Review: Gearless Motor Failures A Mill

2014-9-10  No mill or motor vendor, mill design company or independent consultant can truthfully claim this advantage. So let’s look at the observations in Svalbonas’ paper on gearless drives in [1]. The structural design of mills is much simpler than the structural design of ring motors. Most of the complexity in a mill is related to bearing design.
