I mounted the sensors in the way I suggested in the previous post.
Was very pleased that it started up using an 18 fet Lyen esc (movie).
But I ran into a problem at higher rpms (no load). At about 70-80% throttle the motor stops.
When I'm carefull with the throttle I can get it passed this point but then the motor sound changes a bit and the phase wires start to heat up.
So I think there is a timing issue? Could it be that I hit the rpm limit of this controller? Can't seem to find any information about max rpm.
The motor has 12 pole pairs and should run 6000 rpm at 40V, so 72000 erpm.
The signals coming from the hall sensors still look good on the scope when this happens.
