Brushless motor controller belongs to the machinery, mechanical use after a long time, with the application of new products, will be gradually phased out, then how to prolong the life of the brushless motor controller, is that we need to think of the problem. The following is the problem, talk to you. Brushless motor controller of wear is mainly on the bearing, from the mechanical point of view, brushless motor controller is almost a maintenance-free motor, when necessary, the only need to do some cleaning maintenance. Next comparison, know brushless motor controller, a brush motor controller is relative to the advantage in where, but everything is not absolute, have low speed torque motor controller performance, such as large torque characteristics is the brushless motor controller can not be replaced, but in the context of use and ease of brushless motor controller, with the decline in the cost of brushless controller and brushless technology development and market competition both at home and abroad, the development and popularity of power system is high speed brushless stage, it also greatly promote the development of the model of motion. The brushless motor controller, and compared with brush, less carbon brush, the motor controller of wear is mainly on the bearing. In use after a period of time, so the motor controller for bearing need timely cleaning, change the grease and lubricating oil. The cleaning and oil change time, should by brushless motor controller working environment, working condition, clean degree, 3 - general motor controller for every work6 months, should be cleaned once, again in lubricating oil. When the oil temperature is higher, or motor controller under the condition of poor working conditions, dust is more, need often clean, changing oil motor controller. If use environmental dust too much, the best cleaning once a day. Brushless motor controller to work long hours, also often need to check whether the screw is loose, burn, etc. , such as loose. Tighten nut. Suggestions in the motor controller running work a year later, it is best to overhaul. Overhaul is that the purpose of the motor controller for a thorough and comprehensive inspection, maintenance, and lack of timely replacement motor controller, wear and tear of components, eliminate brushless motor controller inside and outside the dust and dirt, check the insulation condition, clean the bearing and check its abrasion. Found the problem as soon as possible, handle in time. In general, as long as you use the correct and proper maintenance, troubleshooting timely treatment, the working life of the brushless motor controller is very long.
