The basic principles of selecting the motor casing

The basic principle of the correct selection of motor shell: mechanical properties, motor shell starting and braking, speed control and other control performance should meet the mechanical characteristics and production process requirements, impact on the quality of power supply of the motor housing in the work process, the shell of motor power should be within the allowable range according to a predetermined working cooling method in Kiev the situation should be determined in a limited range, according to the environmental conditions, operating conditions, installation mode, drive motor shell temperature rise, the selected motor shell structure, installation and protection, to ensure reliable work of the motor shell. Considering the investment and operation cost, the whole drive system is economical, energy saving, reasonable and reliable.

The routine maintenance of the motor housing is very important to reduce and avoid the failure of the motor in operation. The most important part is the inspection of the circuit and the elimination of any abnormal phenomenon. It is necessary to reduce the number of accidents and improve the operation efficiency of the motor when it is stopped. Inside the motor is not allowed to enter the water, oil, dust, etc., and regularly remove the dust inside and outside the motor. Note that the load current should not exceed the rated value. Pay attention to check bearing heating, oil leakage, etc..

The motor is one of the production equipment, manufacturing of not less than, in order to ensure the normal work of the motor, but according to the rules of normal use and operation process of normal monitoring and maintenance, should also carry out regular inspection, completes the motor maintenance work.

The significance of daily maintenance

Our machinery and equipment can work, it is a very important part of the normal operation of the motor. So motor maintenance is also very important, a lot of people always do not pay attention to maintenance or do not know how to maintain, until the motor problems, the motor can only be repaired, maintenance, then both to spend money, but also delayed work.

Two. How to maintain the motor

Usually, motor maintenance should pay attention to: keep the motor clean, no dust; always check the motor's appearance, to see if there are parts of dislocation; often check the bearing replacement or gas, also check the inlet wire connecting thread.

If you talk about the maintenance of the motor in detail, the main contents are as follows: when the motor is working, pay attention to the working environment, do not be too bumpy state, to prevent damage to the motor or reduce the service life. But also for visual inspection, the fan is working properly, if there is abnormal vibration, coupling connection is reliable, whether the fastening base is fixed, bearing is normal (sound), temperature is normal (infrared thermometer), current is normal (clamp meter), in addition to check the winding motor carbon brush and slip ring. If an exception occurs, it is necessary to quickly repair the motor.
