Understand the defects in operation of the brushless dc motor controller, should do so

in order to further understand the defects in operation of the brushless dc motor controller, when conditions permit, can be checked before disassembly test. Therefore, brushless dc motor controller load test run, check the brushless dc motor controller of each part in detail, such as temperature, sound, vibration, and test the voltage, current, speed, etc. , and then disconnect the load and no-load check experiment was carried out respectively, and measurement of no-load loss and no-load current and and make records. Brushless dc motor controller as before to do so before 1, remove, check the appearance of the integrity of the brushless dc motor controller to use compressed air to blow off the dust on the surface of the brushless dc motor controller, and wipe the surface dirt. 2, choose the brushless dc motor controller decomposition of the workplace, clean up the scene environment. 3, be familiar with the brushless dc motor controller structure and maintenance of the technical requirements. 4, to remove the special tools and equipment required. 5, to cut off the power supply, demolition of brushless dc motor controller wiring and make records. 6, choose a multimeter to test the insulation resistance of the brushless dc motor controller. In order to compare the last overhaul during measuring insulation resistance value, to determine the insulation of the brushless dc motor controller and insulating state change trend, the different temperature measuring insulation resistance should be converted to the same temperature, the average is 75 ℃. 7, test, absorption rate k. When the absorption rate is greater than 1. 33, says brushless dc motor controller is not affected by the damp or wet insulation degree is not serious. In order to comparing with previous data, also will any temperature measured absorption rate should also be converted to the same temperature. 8, all problems after everything checked out, deal with the problems found, reassemble the complete, and run the tests. http://www。 tcmotor。 Com/foshan electrical and mechanical equipment co. , LTD. , brushless motor controller, brushless dc motor controller, dc servo motor controller, planetary reducer, brushless drive, electrical and mechanical, foshan electrical and mechanical equipment co. , LTD. , a landing
