*The quest for power*
Any one who followed my re-build of Aussie Jesters motor all the way through knows we had some ideas regarding power modifications & some of our current limitations regarding controlling these monster tourque machines.
After the 1st re-winding, AJ's motor and reading the #s it was aparent the the resistance was far to low to have any hope of keeping a controller alive at the ampdraw potentials we were creating......
this potential solution: re-wind from distributed LRK to a straight LRK....& then wind the remaining 6 teeth with another set of lrk windings....thus making this 2 motors on a single shaft.
Here are the specs stock # / rewind #s
Model 80/85-170kv
stock- 88 srtands 33gage 16turn DLRK terminated in delta/1 strand 14gage 10 turn terminated in wye x 2
copper cross secction: 17.9/20.7
resistance 23.14/16.5
res. wye 46.8/33.1
res. delta 15.6/11.0
copper weight 3-phases 177g/ 108.8 (times two sets=217 grams)
whats all this mean?
We have a 30% (I rounded the #s from drive calculator) increase in copper in this motor The reduction in turns has maintaind the original KV within a a few % point from stock I calculated 173 from the rewind.
I can now input power from 2-CC HV-160's I will let you guys do the math on peak potentials.
This is the 1st step of utilizing whats available to a mechanic like me to take it to the gassers on a sleeper build. Will be fiting this motor to a bike this evening & seeing how is all shakes out tomorrow afternoon. (getting dark now)
here is the photolog:
10 turns of 1.63 magnet wire
notice the epoxyed ends of the stator & wound with spectra fillimant for insulation
the madusa terminated in Wye. 1 set of black wires & a 2nd set of red
all assembled & wired up for some fun:

whadya thinks????? can i get 60+ on the velodrome with this toy motor......this Hobo's going racing (wait till you see my hack on the ca120 :wink: )
