Micro brushless motor vehicle systems, household appliances, electric tools, industrial automation equipment, medical equipment and other power equipment of the heart. Because most of the micro motor running stability failure rate is low, the preventive maintenance is often overlooked. Science of preventive maintenance for the micro motor, can effectively avoid the sudden stop of unscheduled stops, you can also extend the service life of it, to maintain the output precision, help enterprises to guarantee production quality and reduce the maintenance cost. Under the force of fai teaches you the micro motor maintenance steps and methods:
1, frequently wipe micro motor. Keep clear of the micro motor stand outside of the dust and sludge. If use environmental dust is more, the best cleaning up once a day or so.
2, check and clear for the micro motor terminals. Check the terminal block wiring screws are loose, burns.
3, part of the screw inspection on time, including ground cover screw, bearing cap screws, foot screws, etc. Tighten the loose nut.
4, check the gear, check the coupling or pulley drive, damage, installation is strong; Belt and its connecting buckles are in good condition.
5, micro motor start-up equipment, also want to clear in time to wipe the external dust, dirt, wipe the contactor, check the connection parts for burns, ground wire are in good condition.
6, bearing inspection and maintenance. Bearing in use after period of time should be cleaned, replace the grease or oil. Cleaning and oil changes, should work with the motor, the working environment, clean degree, type of lubricant, 3 - half of each work6 months, should be cleaned once, again in grease. The oil temperature is high, or poor environmental conditions, dust more motor to wash, oil change often.
7, insulation situation of inspection. Insulation insulation ability in different degree of dry varies, so check the micro motor winding drying is very important. Motor damp working environment, workshop have corrosive gas and other factors, can destroy electric insulation. Is one of the most common winding earth fault, the insulation is damaged, the live part and should not be charged metal parts such as chassis touching one another, this kind of failure occurs, not only affect the motor to work properly, will endanger personal safety. So, motor in use, often should check the insulation resistance, also note to check the motor chassis grounding is reliable.
8, in addition to the regular maintenance of motor according to the above a few content of outside, brushless motor, to overhaul a after a year of operation. Overhaul aim was to conduct a thorough and comprehensive of micro motor inspection, maintenance, supplementary motor lack, wear and tear of components, eliminate motor inside and outside of dust, dirt, check the insulation condition, clean the bearing and check its abrasion. Found the problem, handle in time.
