HOW TO REFURBISH MOTOR LAMINATIONS ?

• Motors and generators are often used in extremely harsh industrial environments.

• Protective laminate coatings are applied to the bodies of the machines so that they can perform under duress and provide uninterrupted service for years.

• However, over time and continuous use, the coating tends to lose its strength.

• This can make the motor or generator susceptible to corrosion, abrasions, and breakdowns.

• The easiest method to fix this problem is to refurbish the laminate coating.

STEPS TO REFURBISH MOTOR LAMINATIONS

Page 4: How to Refurbish Motor Laminations

1. WET SAND THE COMPONENT• This is done to remove any kind of corrosion or oxidation that may

be present on the part.

• Use a coarse sanding sponge and a bucket of water to wet sand the part.

• Dampen the sponge slightly and sand the interior and exterior bodies of the component.

• Once the wet sanding process has been completed, allow the component to dry for about an hour.

2. DEBURR THE COMPONENT

• Once the body has dried, you need to deburr the component to remove any protrusions, dents, and ragged edges.

• Attach the rectangular shaped sand paper disk to the bottom of the sander.

• Connect power sander to the power supply.

• Once the power has been turned on place the sander onto the component. Slowly move the sander in a linear motion across the length and breadth of the component.

• Concentrate on corners, edges, and areas where there may be depressions.

3. PREPARE THE COATING ROOM• Generally, coatings are spray painted onto metallic components.

You need a separate room to perform this step.

• Mount a metallic hook and let it hang from the ceiling.

• Cover the room with plastic sheet paper to ensure that the coating will not leak or spread out of the room.

• Hang the component from the metallic hook.

4. SET UP THE SPRAY PAINT MACHINE• Pour the coating into the machine’s coating can.

• Attach the coating can onto the machine.

• Connect the machine to the power supply.

• Ensure that the compressed gas used to perform the spraying process is working.

5. COAT THE COMPONENT

• Slowly spray the coating onto the component in long strokes.

• Coat the surface effectively by spraying in either a side to side or upwards to downwards motion.

• Using this action, completely spray the interior and exterior body of the component.

• Give the coating a few minutes resting time before you apply the second coat.

6. CURE THE COMPONENT

• Once the coating process has been completed, you need to cure the component.

• This allows the coating to solidify and thus provide the component the protection it needs.

• Transfer the component to a curing oven.

• Close the oven and set the temperature. The normal curing temperature is 200oF for about an hour.

• Start the oven and let it cure the component.

7.REMOVE AND INSPECT THE COMPONENT• Once the curing process has been completed, remove the

component and let it rest to reduce its temperature to normal.

• Once this is done, conduct a thorough inspection of the component to ensure that there are no defects in the component.

8. PACKAGE AND SHIP THE COMPONENT• If the component turns out to have no defects, it can be packaged

and shipped for delivery to the client.

TIPS

• You need to keep rinsing and wringing the sponge to ensure that it is only damp and not wet. Change the water if it becomes too murky to see through.

• Before you start the coating process, use the machine on a sample component to ensure that it is working properly.

• If you have an enormous curing oven, you can also use it as the coating room. This can help you to save time.

WARNINGS

• Never perform the coating process without protective clothing. Always wear a chemical protective suit with a hood, rubber gloves, and chemical protective boots.

• Never coat the component without using an air purifying respirator in confined spaces.
