() motor for a ball mill, to Lafarge Cement in France in 1969. Since then, GMD systems have become larger, more powerful, and are now operating at higher altitudes even above 4,000m where the extreme environmental and boundary conditions challenge the lifetime of a GMD. Under these demanding conditions, only the
