Tanks!
At the moment we drive without cooling van in the motor and we reatch 55 degree
i will cnc mill a van out of plastic Pom
the magnets are n45 in sice 40x10x5mm the temp. limit ist 80 degree
the alternator is a bosch 150a
yes the rotor is aluminium and steel but it ist the cheap...
Nice build!
perhaps you can mode your controller shunt it is described there very good

I get around 100 Amp out

but i dont now waht your battery does
Today we made a Forest test and had a problem with to mutch power :)
We reatch now 66 kmh and max 10kw in fast acrelation on street .
We think about make it faster up to 75 kmh that we lose some to torque.
It ends with a crash 2 meter down in litle creek but we are ok.
we did some tests with 100v and 100a it runs nice but the controller reatch his rpm limit and past 6 minutes full trottle we had on the stator 25 degree centigrade but the st52 iron rotor was 52 degree centigrade
the ceap 96v 1500w controller gets an shunt and conductor path upgrade
we are...
Thanks
yes the Tesla rotor looks good and i think we can build a rotor like this but i can`t find a seller for the
electro sheet and i do not undestod how they magnets cascade
Hi,
we build am Electric motor bike and the game is for us most power we can handle with MTB parts

at the beginning we just convert a bosch alternator with 103x40mm rotor to a BLDC but at 70 volt and 50 amp the magnetic field jump...
now we change the wiring now from star to triangle so the speed increase from 30 kmh to 53 kmh with 70 Volt from the 18s battery
the acceleration is crazy fast from 0 to 30kmh we get wheelspin or the front comes up at full throttle :D
we make a video at daylight if we get some time...
The motor in now back in place.
with the new magnets the top speed go down from 37kmh to 30 kmh but now the magnetic field is stable.
we change the wiring now from star to triangle so the speed increase x1,7 to 51kmh
and after that we cage the battery from 18s to 24s to get 68kmh top speed...
