How to Rewind an Electric Chainsaw Rotor327

Electric chainsaws are a powerful tool that can make quick work of cutting through wood. However, if the rotor in the chainsaw's motor burns out, the saw will no longer work. Rewinding the rotor is a relatively simple process that can be completed in a few hours. Here are the steps on how to rewind an electric chainsaw rotor:

1. Safety First

Before you begin, make sure to unplug the chainsaw and allow it to cool down completely. Wear safety glasses and gloves to protect yourself from any flying debris.

2. Remove the Rotor

The rotor is located inside the motor housing. To remove it, you will need to remove the motor housing screws and carefully lift off the housing. The rotor will be attached to the motor shaft by a nut or bolt. Remove the nut or bolt and carefully pull the rotor off the shaft.

3. Inspect the Rotor

Once you have removed the rotor, inspect it for any damage. If the rotor is cracked or broken, it will need to be replaced. If the rotor is not damaged, you can proceed to the next step.

4. Remove the Old Windings

The old windings are the copper wire that is wrapped around the rotor. To remove the old windings, you will need to use a sharp knife or a pair of wire cutters. Carefully cut the windings away from the rotor, being careful not to damage the rotor itself.

5. Clean the Rotor

Once you have removed the old windings, clean the rotor with a clean cloth. This will help to remove any dirt or debris that may have accumulated on the rotor.

6. Wrap the New Windings

Once the rotor is clean, you can begin winding the new windings. Start by wrapping the wire around the rotor in a single layer. Make sure that the wire is tight and that there are no gaps between the windings. Once you have completed the first layer, continue winding the wire around the rotor, overlapping the previous layer by about 50%. Continue winding until the rotor is completely covered.

7. Solder the Windings

Once you have finished winding the new windings, you will need to solder them in place. To do this, use a soldering iron to melt solder onto the ends of the windings. Be careful not to overheat the solder, as this can damage the windings.

8. Test the Rotor

Once you have soldered the windings, test the rotor to make sure that it is working properly. To do this, connect the rotor to a power source and turn it on. The rotor should spin freely and without any noise or vibration.

9. Reassemble the Chainsaw

Once you have tested the rotor and made sure that it is working properly, you can reassemble the chainsaw. Start by placing the rotor back on the motor shaft. Then, replace the motor housing and tighten the screws. Finally, plug in the chainsaw and turn it on. The chainsaw should now be working properly.

Tips

Here are a few tips for rewinding an electric chainsaw rotor:
Use a high-quality copper wire for the windings. This will help to ensure that the rotor is durable and long-lasting.
Make sure that the windings are tight and that there are no gaps between them. This will help to prevent the windings from overheating and failing.
Be careful not to overheat the solder when soldering the windings. Overheating the solder can damage the windings.
Test the rotor before reassembling the chainsaw. This will help to ensure that the rotor is working properly and that the chainsaw will be safe to use.
