Solutions to DC permanent magnet motors after getting wet

The DC permanent magnet motor is composed of stator magnetic poles, rotor (armature), commutator, brushes, casing, bearings, etc., while the stator magnetic poles (main magnetic poles) of electromagnetic DC motors are mainly composed of iron core and Composed of field winding.

According to the different excitation methods (called excitation in the old standard), they can be divided into series-wound DC motors, shunt-wound DC motors, separately-wound DC motors and compound-wound DC motors. And because of the different excitation methods, the rules of the stator pole magnetic flux (generated by the stator pole excitation coil after being energized) are also different.

However, sometimes in some harsh environments, DC permanent magnet motors may become damp. So how should we solve this damp phenomenon? Let’s discuss it together below!

The solutions to DC permanent magnet motors getting wet are as follows:

DC permanent magnet motors are still very common in industrial production. However, when they are working, especially on rainy days or in humid environments, the product itself and even its use will have an impact. So this Everyone needs to pay attention when making resettlement.

1. Excitation coil drying method: The excitation coil drying method is to wind an excitation coil around the iron core of the stator coil of the DC motor, and pass in alternating current to cause the stator to generate magnetic flux, and then rely on its iron loss to dry the stator of the reduction motor.

2. Welding machine drying method: Before operating the AC welding machine drying method, connect the terminals of the damp motor windings in series and ground the chassis, so that the three sets of windings can be heated and dried.

3. External heat source heating method: For the DC permanent magnet motor that is affected by moisture, we can disassemble and inspect it, then use a high-power incandescent bulb to put it inside the reduction motor, and then bake it, or put the reduction motor Enter the drying room for drying.

Regarding the solution to dampness in DC permanent magnet motors, the above introduction is detailed enough. According to the content in the article, you can use it flexibly in future use. In addition, when handling it, we need to pay attention to the fact that we also need to operate it in accordance with the standards. In order to use it better, we hope that everyone can implement some protective measures against it to avoid unnecessary trouble in the future.
