Motor Soldering Guide

Steps to Solder the Motor Connectors

  1. Prepare the Motor and Wires
    Take the motor out of the box.
    Use a wire cutter to remove the original connectors.

  2. Strip the Wire Insulation
    Use a wire stripper to remove about 3mm of insulation. untwined wire Twine the exposed wire so no individual strands come loose. twined wire

  3. Prepare the Connector
    Grab a male connector and place both the wire and connector on a soldering mat.
    Align the tip of the wire inside the connector so that the remaining insulation meets the end of the connector. Notice the tip of the cone shown below Connector Cone Secure the wire and connector by using a heavy object to press down on the wire and another object to hold the connector in place.

  4. Prepare the Soldering Iron
    Turn on the fume extractor/fan and your solder iron
    Set the soldering iron to 400°C (750°F).
    Clean the tip of the soldering iron and apply solder around it to tin the tip (important).

  5. Solder the Wire to the Connector
    Press the iron at the point where the wire and connector meet.
    Caution: The iron should never touch the connector's end. The one below is scrapped scrapped connector Press the solder against the iron—it should melt immediately.
    Gently push the solder toward the iron to feed it into the joint.
    Continue feeding until there is enough molten solder to fully cover the wire and any gaps. soldering Caution: Avoid getting solder on the outer surface of the connector.

  6. Check and Secure the Solder Joint
    Lift the soldering iron and allow the solder to cool.
    If the result is unsatisfactory, repeat steps 5-6 to reshape or add more solder.
    Once properly soldered, let it cool and use pliers to grab the connector end and gently pull to test its strength. goodsolder

  7. Apply Heat Shrink Tubing
    Slide a heat shrink tube of proper diameter and length onto the connector.
    Pull it down to cover the circular bulge on the connector.
    heatshrink Use a heat gun to shrink the tubing until it fully adheres to the joint.

  8. Repeat for Remaining Connectors
    Repeat steps 2-7 for all three connectors.
    Inspect the solder joints to ensure quality.

  9. Commission the Motor
    Once all connectors are properly soldered and secured, the motor is ready for commissioning. newconec

  10. Clean up
    Turn off devices
    Dispose of all the litter
    We use lead-free solder but we treat it as leaded, so don't forget to wash hands
