What are the effects of different installation methods on the temperature of motor bearings？

We (SIMO motor, Chinese time-honored motor manufacturer)have conducted a comparative analysis of the control of some connections based on the rationality of motor bearing design and operation. Motor designers and manufacturers are more concerned about motor housing performance and dimensional compliance, and during motor operation, there is no or no opportunity to truly understand and understand certain performance relationships.

B35 installation motor-storage system heat dissipation control requirements Compared with B3 assembly motors, B35 motors must be connected to the equipment through flange end covers, and in addition, the base must be assembled and fixed, that is. H in the horizontal and vertical directions, around the connection between the motor shaft end and the equipment.    Of course, the connection between the motor flange cover and the device forms a relatively independent cavity, and the bearing at the motor shaft end has an additional barrier to the external environment, that is, the heat emitted by the bearing system cannot directly interact with the heat exchange, especially when the temperature of the equipment components is relatively high, the impact on the bearing temperature at the motor shaft end is greater.

However, during the motor test process, in most cases, the test environment is not created according to the actual operation of the motor, and both the installation environment and the actual operation environment of the motor test stage are very different from the actual operation of the motor, resulting in many storage system problems. To avoid these problems, both motor and equipment manufacturers should consider manufacturing some flange cover design parts to ensure the ventilation and heat dissipation requirements of the bearing system when the equipment and motor are running. B35-installation Motor Installation Non-stop Oil Filling and Drainage Structure In most motors, the bearing system requires non-stop oil filling and drainage structures.

There are two types of oil filling and drainage structures for motors, one located on the bearing cover and the other located on the end cover. For the electric motors installed on B3, whether on the end cover or on the bearing cover, as long as the equipment is not damaged, the oil filling and draining can be completed, and the fact that the motor is docked on the device must be considered. In the actual fault protection analysis of the motor, it was found that some motors only have oil injection holes but no oil drain holes; for small motors, this is not a big problem, but for large motors, especially those that require frequent grease replacement. The problem may be more complicated. In serious cases, the grease may even flow into the inner cavity of the motor, causing other quality problems.
