cogging is obvious and it’s the pull of iron to permanent magnets

with unpowered cogging you store energy (like a spring) then get most or all of it back:

@professor_shartsis

i’m not entirely convinced the cogging results in any net rolling resistance with enough inertia… and I thought FOC is supposed to take care of the torque ripple.

^when I release the wheel it spins some from stored energy
