Mr. Methods shipped me a new 9c 6x10 rear motor which arrived Thursday. I currently have a 9x7, and an 8x8. Figured I'd give lower speed, better hill ability a try. Also I've been seeing a couple threads having success at liquid cooling, so I figured why not. So far I've...
1. Bench tested new motor. It works.
2. Tore down new motor.
3. Cut phase/hall wires and ripped them out.
4. Epoxied & baked magnet ring.
5. Epoxied & baked windings.
6. Installed thermal sensor with high temp silicone sealant between 2 phase wires at the windings.
7. Drilled axle out with 5/16" bit.
8. Stripped 10awg teflon coated wire & heat shrunk each wire.
9. Heat shrunk 3 phases & 7 30awg teflon coated wires and inserted through axle.
10. Soldered all wires inside motor with silver solder (higher melting temp).
11. More silicone sealant around wires near axle to prevent any liquid ingress/egress.
Yet to do:
12. Install tiny vent tube for breathing/filling of ATF fluid....Edit: DONE
13...Did I forget anything?
Pic of progress so far.
If all goes well, hopefully I'll be able to report temps. Trying to decide if I want to run without fluid first (to get a baseline temp).
Edit: Probably should get a no load current value first also. Although, I run a heavy tire/tube combo, so it may be skewed up a bit.
