Introduction to the maintenance of brushless dc motor controller

Motor controller in use process will be affected by some damage, dc motor controller is a kind of our commonly used a motor controller, dc motor controller in brushless dc motor controller in use will produce some problems, the problem of motor controller is for the use of the machine will have a lot of damage, will affect our daily production work and so on, we need to work out solutions to some of brushless dc motor controller to provide maintenance, the small make up to you to introduce the daily maintenance of brushless dc motor controller. 1, before disassembly, want to use compressed air to blow the net surface dust, motor controller and scraped clean surface dirt. 2, select the disintegration of the motor controller working site, clean up the scene environment. 3, familiar with the motor controller structure characteristics and maintenance technical requirements. 4, ready to collapse the required tools, Including special tools) And equipment. 5, in order to further understand the defects in operation of the motor controller, conditional can before disassembly when doing an inspection test. For this, turn motor controller with load test, check the motor controller in detail various parts, such as temperature, sound, vibration, and test the voltage, current, speed, etc. , and then disconnect the load, do a no-load check test, no-load loss and no-load current is measured and recorded. 6, cut off power supply, dismantling motor controller external wiring, recorded. 7, the appropriate voltage test motor controller insulation resistance by megger are. Maintenance in order to keep pace with The Times when measured insulation resistance compared to determine the motor controller changing trend and insulation insulation condition, different temperatures shall be measured insulation resistance value conversion to the same temperature, the average conversion to 75 ℃. 8, test absorption than K. When the absorption ratio greater than 1. 33, show that motor controller insulation or degree of be affected with damp be affected with damp be affected with damp be affected with damp or it's nothing serious. In order to compare with previous data, also want to add any temperature measured absorption than the conversion to the same temperature. Brushless dc motor controller belong to free maintenance motor controller, as long as you are when use, don't beyond the scope of rated parameters of the motor controller, is ok. When use must pay attention to standard use temperature of the motor controller. The temperature rise of the motor controller during normal overload controller will rise.
