How to swap Hypercore to Fungineers motor connector

This guide will help you install a Fungineers motor cable in your Hypercore motor. This method replaces the entire cable, leaving you with a reliable and professional-looking conversion that will last for years. No splicing, no cable bulge, and extra length tucked inside the axle for future length adjustments.

Modifying the internals of a motor can be daunting! Please familiarize yourself with the full process before starting. Nothing worse than getting 3/4 finished and realizing you forgot to order sealant or replacement bearing o rings!

Tools:

  • allen keys
  • soldering iron
  • solder sucker or solder wick
  • side cutters
  • wire strippers
  • flat head screwdriver (to poke the black sealant out of the axle)
  • tweezers (to untie and tie the string)
  • heat gun

Materials:

  • Hypercore
  • Fungineers motor connector (motor side)
  • solder
  • heat shrink
  • flowable silicone (or another heat resistant sealant)
  • replacement bearing o rings (XR or GT/Pint)

Steps:

  1. take the stator out of the hub:

  2. disconnect the old motor cable wires:

    • untie the string holding down the wires and save it for later
    • take the heat shrink off of the phase wires
    • desolder and disconnect the phase wires from the windings
    • note: if you accidentally cut one of the motor windings, you’ll need to scrape off the nonconductive coating before resoldering the wire back together
    • take a picture of the hall sensor PCB to remember the order of the wires!
    • unsolder the small wires (temp + hall sensors)
  3. remove the old cable:

    • carefully pick away as much of the white sealant from around the phase wires as you can
    • pick away as much of the black sealant from inside the axle as you can
    • remove the rubber seal from the motor cable side of the axle
    • pull the old motor cable out of the axle
  4. insert the new cable:

  5. connect the new phase wires:

  6. connect the hall and temp sensor wires:

  7. secure and seal the new cable:

    • tie the string back in place to keep the wires away from the rotating cover plate
    • use flowable silicone or another heat resistant sealant to waterproof and further hold the wires in place
    • [optional for further waterproofing] adjust the length of the motor cable in the axle, then fill both side of the axle with silicone to fully seal the axle
    • let the sealant cure overnight
  8. reassemble the motor:

    • install new o rings on the axle
    • slide the cover plate over the new motor connector and press into place
    • spin the cover plate to ensure the wires aren’t rubbing
    • attach a rail to the plate side of the stator and lower the stator into the hub
    • align the bolt holes in the cover, then press the stator firmly down into the hub
    • reinstall the cover plate bolts, tightening in a star pattern to apply even pressure around the plate
    • reinstall motor into your board and re-run motor wizard

we upgraded your account, you can now post more pictures. :slight_smile:
can you try to copy and paste the images into the first post? let me know if that works.

Hoping to collab on some wiring diagrams for the superflux, hypercore.
Female:

Basically correct me if im wrong but you just need to follow the red, black ± and white for temp rule and you will be coolin.
This might be needed. It is missing the labels for standard color, and what the pinout to halls actually is.
