Electric motor noise: How to identify the cause and …
Usually, the washer exerts a force on the outer race of an axially free ball bearing (typically the non-drive end) to eliminate the internal clearance between it and the locked bearing. This causes each ball to follow the same raceway path in each bearing, which decreases noise from balls rattling within the raceway and cage, while reducing ...
