1. The significance of motor case power selection

The selection of rated power of motor case is a very complex problem. Under load, if the rated power of the motor case is too large, the motor shell is often in light load operation, the capacity of the motor shell itself can not be fully utilized, and the operation cost will be increased due to the low operation efficiency and poor performance of the motor shell.

The requirement of rated power of motor shell is small. If the current of motor shell exceeds the rated current, the loss in motor shell will increase, and the efficiency will be low. Moreover, the service life of motor shell will be affected, and the insulation performance of insulation material of motor shell will be damaged or even burned out. Of course, the rated power of the motor shell is small, it may not be able to drag the load at all, which will make the motor shell in the starting state for a long time and cause overheating damage. Therefore, reasonable selection of power and correct maintenance of the motor shell is essential.



2. Motor case maintenance requirements

Ensure good lubrication of motor during operation. General motor running about 5000 hours, you need to add or change the grease, bearing overheating or in the process of operation, found lubrication transformation, hydraulic timely grease. When changing the grease, the lubricating oil of the old motor housing should be removed, and the gasoline in the oil tank should be cleaned, and the bearing and bearing cover should be cleaned, and then the inner and outer ring cavities of the bearing should be filled.
