What are the common reason of fault of the electromagnet?

The fault of the electromagnet is that the electromagnet does not move ( failure ), the electromagnet is burnt down, and the work is weak.

The common reason is that the wire joint is loose or dropped, the mechanical assembly is not normal, the coil is broken, short circuit or the electromagnet has been burned down, and the suction is weakened, the armature can not be inhaled quickly or simply cannot be sucked in.

When the armature is pressed and the armature is found dead, the electromagnet is burned down. The reason why the electromagnet is burnt is that the armature is blocked; or the conversion contact adhesion, causing the electromagnet to work for a long time under the high current, the coil may short circuit, or the button press will not pop up, so that the two coils are always connected in series together, the armature can not suck, and a long time will burn the coil.

The coil is in good condition, but the noise is large when the coil is energized, which is caused by the poor contact between the armature and the yoke. The corrosion of the contact surface is stained with dust, wear and deformation and iron filings, etc, which will cause a great noise in the work of the electromagnet, and the rupture or loss of the short circuit ring will also be strong vibration and noise.

Another common reason for the inability of the electromagnet to work are that the power supply voltage is too low, and the contact of the conversion contact is bad. For the coil is normal, you can determine the resistance between the two terminals when the button is not pressed and pressed. When the coil is not normal or the electromagnet is burned, the whole electromagnet needs to be replaced.
