The daily maintenance of brushless DC motor should pay attention to the following eight points of attention∶

       1Clean the motor.Dc brushless motorIt is a synchronous motor composed of a motor body and a driver, and is also a typical mechatronics product. Timely remove the dust and sludge outside the motor frame. Like some production use environment, more dust is best can be done every day cleaning work.

       2Check and wipe the motor terminals. Check that the terminal screw of the terminal box is loose and burned.

       3Check the fixing parts, including grounding footing adjustment screws, end cap screws, bearing cap screws, etc. Check whether loose nuts are tightened.

       4Check the transmission condition, check whether the pulley or coupling is damaged, and whether the installation is firm; Whether the belt and its coupling buckle are in good condition. Check whether there are burn marks on the wiring area and whether the grounding is good.

       5, inspection and maintenance of bearings. Bearings should be cleaned after a period of time and replaced with grease or lubricating oil. Clean and change the oil. Different working environments, degree of cleaning work, depending on the type of lubricant for each job3-6Half of the month, should be cleaned once again to change the grease. When the oil temperature is high, or the difference in environmental conditions, dust more regularly clean the oil changes.

       6Check the insulation condition. The insulation design capacity of insulating structural materials is different due to the design, material and use performance, each manufacturer will be somewhat surprised, but we check the controlBrushless DC motorThe drying of the winding is very important, the working and living environment is getting wet, There are corrosive gases and other factors in the workplace that will cause damage to electrical insulation. The most common fault is the winding grounding system.That is, the insulation is damaged, making the live part dust Filth. Check insulation Clean the bearing and check for wear. Identify these problems and deal with them promptly and effectively.

       Under normal circumstances, as long as it is correct, proper maintenance, the fault is found in time, the working life of the brushless DC motor is still very long.
