Recently Xiaobian received user feedback that their air compressorThe motor hums and doesn't turnHow should I fix this？If we want to solve this problem, we must first know what is the cause of the failure that causes the motor to buzz and not turn？Xiaobian has made the following arrangement on this issue:

First, the motor buzz does not turn the factors:

1, starting capacitor aging, resulting in reduced starting current;

2、Capacitance damage of the motor;

3. The lubricating oil of the bearing of the motor dries up, causing the friction resistance to increase;

4, the possibility of capacitor damage is greater。

Second, the motor humming does not turn the repair method is as follows:

1, due to the power supply connection problem, resulting in single-phase operation;Need to check the power line, mainly check the motor wiring and fuse, whether there is line damage。

2, the stator internal first end position is wrong, or there is a broken line, short circuit;Check brushes, slip rings and starting resistors for each contactor connection, breakage and short circuit。

3, the rotor circuit of the winding motor is open to break the line;Check the engagement of brushes, slip rings and starting resistance contactors。

4, the motor load overload;The second case is to unload the motor after unloading or half-load start。

5, by the drag machinery stuck;Uninstall the dragged device and locate the fault from the dragged device。
