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

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.

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 solution

the next rotor will be made of transformer steel lasercutted.
