Automotive Armature As a new type of energy-saving, CNC integrated motor, it shoulders the important task of revolutionizing the existing motor structure to achieve the goal of more energy-saving and longer-life motor innovation. Below, we will discuss the precautions for using automotive armatures?
There are also some precautions when using an automotive armature. For example, before disassembly, use compressed air to blow away dust from the surface of the motor and wipe off surface dirt. Choose a suitable location for disassembling the motor and clean the surrounding environment. It is also necessary to be familiar with the structural characteristics and maintenance technical requirements of the automotive armature. Only in this way can the necessary tools and equipment for disassembly be prepared. To further understand the defects in the operation of the automotive armature, if possible, an inspection test can be carried out before disassembly. For this purpose, the automotive armature is placed under load for a trial run, and the temperature, sound, vibration, etc. of each part of the motor are carefully checked, and the voltage, current, and speed are tested. Then, the load is disconnected, and a no-load test is performed separately to measure the no-load current and no-load loss, and records are made. After all these are completed, the power can be cut off, the external wiring of the motor can be removed, and records should be made.
When using an automotive armature, a megohmmeter with a suitable voltage must be used to test the insulation resistance of the motor. In order to compare the insulation resistance value measured during the last inspection and judge the change trend and insulation state of the automotive armature, the insulation resistance values measured at different temperatures should be converted to the same temperature, generally 75℃. Next, the absorption ratio K needs to be tested. When the absorption ratio is greater than 1.33, it indicates that the automotive armature insulation has never been damp or the degree of dampness is not serious. In order to compare with previous data, the absorption ratio measured at any temperature also needs to be converted to the same temperature. Regularly check whether the sound of the automotive armature during operation is normal. If there is an abnormal sound, the machine must be stopped immediately for inspection, because the most worn part in the entire brushless motor is the bearing part. If there is an abnormal sound, it is very likely that the bearing is worn. If the wear is excessive, the bearing can be replaced and continued to be used. However, if the bearing is not replaced and continued to be used, the friction during the swinging and rotating process will accelerate the wear of other parts of the brushless motor, which will definitely accelerate the wear of the entire automotive armature.
After the introduction of the above content, we have a further understanding of the precautions for using automotive armatures. We will no longer feel unfamiliar when we see it again, and problems will not occur frequently during use. Okay, that's all for today's content. I believe there will be more exciting knowledge points to come.
