Abstract
The use of three phase asynchronous motors in electric locomotives instead of single phase commutator motors has eliminated the wear problem helped by the elimination of a commutator. High motor speeds gives rise to two problems with the bearings: sliding occurs between the rollers and inner ring raceways; and the relubrication interval is drastically reduced if the limiting speed for grease lubrication is approached. These problems were addressed by modified design using cylindrical roller bearings with optimized contact geometry, polyamide cages, and oil lubrication with an efficient oil barrier between bearing and rotor.
