I had some time to spin the motor up with a rc sensorless esc and no load on the motor it takes 5.96A @ 44v ( I still think this is really poor compared to the other motors that I have ) anyway, it seems from what other people have said about this motor that is about right. I'm hoping with hall sensors fitted this can be improved but Im not holding my breath.
The bad news is with the motor connected and powered up just through the crank the motor draws 15A @44v
so there is a tight spot some where and Im hoping that it is only the motor mount needs a bit of adjustment, worst case it could be the crank is not true ( this may have been the result of having to rework the crank to take the additioal 3mm off for the wider main bearings ), if this is the case Im a bit stuck at the moment as of a way to quick fix it. I may have to remove the crank and rework it on the lathe which is something I would like to avoid if I can. But I think I am still on track to have the transmission all up and running by this coming weekend, fingers crossed.
1day goes by
I took the crank out And stuck it back in the lathe in work and got some else to check it and it was slightly out
and now its as good as its gonna get unless I start again. The crank runs a lot smother now but I think the motor mount may still need a bit of tweeking also, I havent re-fitted the motor yet I had a few other things I needed to do ( totally unrelated
) tomorrow I will re-fit the motor and adjust the motor mount hopfully I can get the crank current down to a decent level, then we are all systems go for testing
