Brushless motor controller in use matters needing attention

by:Hoprio     2020-07-19

the brushless motor controller in use need to pay attention to matters of brushless dc motor controller as the using field is more and more big, the use of more and more customers, utilization is more and more high, in the market of the brushless dc motor controller failure rate must also subsequently and growth, the need to pay attention to the brushless motor controller using matters will also cause enough attention. Brushless motor controller while the basic is maintenance free in design, but if in use do not pay attention to are also very easy to failure, so the brushless motor controller when use what points we need to pay attention to? ( 1) Before disassembly, want to use compressed air to blow the net surface dust, brushless dc motor controller and scraped clean surface dirt. ( 2) Choose motor controller disassembly work, clean up the scene environment. ( 3) Familiar with brushless dc motor controller structure features and technical maintenance 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 the power and external connection, demolition of brushless dc motor controller completes the record. ( 7) Choose appropriate voltage insulation resistance by megger test motor controller, in order to keep pace with The Times maintenance when measured insulation resistance compared to judge insulation change trend and the status, the motor controller should be measured at different temperatures of insulation resistance value conversion to the same temperature, the average conversion to 75 ℃. ( 8) Test absorption ratio 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 not serious, in order to compare with previous data, also want to add any temperature measured absorption than the conversion to the same temperature. When use, controller of brushless dc motor parts and equipment itself, is the place that we need to focus on to observe maintenance, equipment in one aspect of the damage may be because the smallest details of a neglected, perhaps the motor controller when the installation is not installed properly, may be in use without serious operation, but whatever the reason, in the final analysis, is when we use the brushless dc motor controller, brushless motor controller need to pay attention to the above said matters need to pay attention to in use.
