So I made a great deal of mods.
Fixed my motor hall sensors. They may not have been smoked, but the wires were completely torn. I found evidence of water damage all over.
Riding it now the controller cuts out at 360amps phase indicating a shorted winding likely due to water damage. But now I can run field weakening and increase top speed above 69mph.
The motor was full of gunk; ferrofluid mixed with bits of black hot glue and wire debris all over. Cleaning it all took 2 hours on its own. PB blaster worked great. The bearing seals separated on the inside and cleaned and repacked those too. Sealed side covers with fresh RTV.
Put the 80rr tire while the motor was out, what a difference in handling.
Increased battery voltage to 80v nominal or 22s by adding two cells in series, making a custom 90 degree bus bar and running a long cable back due to odd number of series strings.
Full charge now technically 92.4v, but my controller is warrantied only to 90v so I only charge to 4.09v per cell. Will increase battery cycle life significantly.
I hit 78mph on 88v but ran out of road. Yesterday I overcharged to 4.23v at 93v total and hit 86mph. With better fitting pants and jacket I could probably hit 88mph.
Since I’m using the middle ~70% of the battery, charging 80% of that takes about 30 minutes on a Level 2 station at 4100-4500 watts (3900wh pack).
my best build yet.
Since I have to replace the motor and the rim too, I may go to a higher speed wind and a wider rim to run a fatter tire and have more strength in the rim to prevent dents. Just dented the rim again somehow. Just want better efficiency at freeway speeds. The higher speed wind motors can also handle higher phase and battery amps. Currently with smoked 14.4kv motor I am pushing 17kw, before was pushing 23kw. The 16kv motor can handle ~26kw.
