Electric motor bearings
The purpose of a bearing in an electric motor is to support and locate the rotor, to keep the air gap small and consistent and transfer the loads from the shaft to the motor. The bearings should be able to operate at low and high speeds whilst minimizing frictional loses. At the same time the bearing must be economic and require absolutely minimal maintenance (if any).
The following points should be considered for bearings during motor design
Loads
- Weights and forces involved
- Power transmitted
- Magnetic pull as a result of unsymmetrical air gaps
- Dynamic forces due to inaccurate adjustment
- Out-of-balance situations
- Pitch errors in gears
- Potential thrust loads
Heavy loads are usually left to roller bearings and lighter loads are carried by ball bearings. Drive forces are only taken into consideration when belts or gears are used. When belts or gears are used then radial and axial forces can develop. Evaluating the magnitudes and directions of all these loads will have direct relevance on your choice of bearing. For example, cylindrical rollers can carry high radial loads but virtually no axial loads. Other bearings such as angular contact ball bearings can carry radial and axial loads.
Speed
The prescribed shaft speed will have a direct effect on the choice of lubricant, bearing size, cage design, internal clearance and shieldal types. Induction motors and pulse modulation motors can produce electrical pitting or ribbing on bearing raceways, hence insulated bearing options may want to be considered.
Bearing life
The life of a bearing is defined as the number of revolutions (or the number of operating hours at a given constant speed) the bearing can endure before the first sign of fatigue. The service life of a bearing depends to a large extent on the operating conditions while procedures used to mount and maintain it are equally important.
Lubrication
Grease lubrication should always be used where possible in motor applications. |
