Installing the Winding Terminator.
The
winding terminator is a small circuit board that serves as a terminal strip for
the winding connection. The idea is to
eliminate all bending and motion of the magnet wire leads coming from the
stator, and keep them as short as practical. Any flexing and motion
should take place in the multi-strand leads going to the controller.
After
the stator is wound and mounted on the bearing tube, slide the terminator on
the bearing tube and stop about half way to the stator. Remove the
insulation from the winding leads up to about 3 mm from the stator. Now
thread each of the bare winding leads through its own small hole in the
terminator. Now you can slide the terminator closer to the stator and at
the same time loop the 3 winding leads around the terminator and through the
terminator hole again. When the terminator is where you want it and the
winding leads are in position, you can apply instant or epoxy glue to secure
the terminator to the bearing tube. Then apply solder to the winding
wires and solder dots around the small holes on the terminator
board. A generous dab of solder is best; just don't build a short between
leads. When you’re ready to attach the leads to your motor connector or
ESC, pre-solder or "tin" the leads after removing about 2 mm of
insulation. Then just place them on the dabs of solder and touch it with
a heated soldering tip. No heat shrink is needed unless you cut back too
much insulation. The direction the wires leave the terminator might need
to be adjusted for some installations. Just apply heat and reset the wire
in the dab of solder to get it just the way you want it.
