Common small knowledge of brushless motor controller, do you really understand

Brushless motor controller of the common knowledge, to see if you know a few: 1, as before, using compressed air to wipe the motor on the surface of the dirt. 2, brushless motor controller working place clean. 3, the structure characteristics of the motor controller and maintain technical requirements to clear. 4, ready to collapse the needed professional tools and equipment. 5, check the brushless motor controller of each part in detail, such as temperature, sound, vibration, and test the voltage, current, speed, etc. , and then disconnect the load, light alone. Check test, measurement of no-load loss and no-load current and record is good. 6, when power cut, to remove the motor wiring of the controller, and record the value. Above is the common small knowledge of brushless motor controller, do you really understand?
