How to prevent DC permanent magnet motor from being blocked

During the use of the DC permanent magnet motor, it may occasionally become blocked, and this phenomenon is ly caused by the motor being used, improperly designed, or not properly maintained. After this problem appeared, many users were troubled and didn't know how to solve it. So today everyone will learn with the editor how to prevent DC permanent magnet motors from being blocked!

Regarding the phenomenon of blocked DC permanent magnet motors, of all, don’t worry too much. We can consider it from the perspective of energy conservation. When blocked, there is no power output and can only be expressed in the form of heat energy. And this heat energy comes from current. Increase; when the rotor is blocked, the resistance is small and the current is high, so in terms of its current setting, we can perform appropriate control according to needs, which can well prevent the DC permanent magnet motor from being blocked.

When the generator is running, the windings bear greater excitation force and are more susceptible to damage by electromagnetic force. Under normal circumstances, the end fastening structure with reasonable design and reliable technology can ensure the long-term safe operation of the DC motor generator within the normal vibration range.

However, generators with poor design and manufacturing quality may easily loosen the end fastening structure after running for a period of time, causing the insulation of the wire rods to wear. If not handled in time, it will cause the DC permanent magnet motor to It will eventually develop into a catastrophic phase-to-phase short circuit accident.

The phase-to-phase short circuit accident caused by the loosening of the stator winding ends and the wear of the bar insulation is sudden and difficult to repair. The corresponding losses are often ly serious, so we should pay special attention to it, which can easily to blockage. dead phenomenon.

In addition, everyone also needs to pay attention to: when using the DC permanent magnet motor, you must pay close attention to its overall usage, deal with it in a timely manner if it can be avoided, conduct regular safety inspections on it, and perform regular maintenance on it. work to ensure equipment usage.

The above are the relevant measures to prevent the DC permanent magnet motor from being blocked. The content is very comprehensive. I don’t know if you have a complete grasp of it and whether you can fully understand the operation of the entire process. So through the in-depth explanation of this article, I hope that everyone can solve the problem alone in the future, or prevent this kind of situation from happening, and strive to achieve zero damage!
