Just wondering why one would WANT a flywheel on an EV??
It's just added inertia - necessary on an ICE; useless - detrimental - for an electric motor.
If you need a crank angle sensor, there are lots of much lower inertia methods - for example Paul's last setup.
Paul - is there any possibility of ( in a useful way ) connecting your new motor to a much smaller shaft? Something like an exposed back shaft?
