Neu vs. Lehner

[Dafni]

You don't have to take the Neu apart to see the rotor. Through the holes on the motor you can see how the "core" of the rotor is not actual magnet. You have those 4 magnets attached to this core.
As opposed to a 2-poler, where the magnet is a solid cylinder (well, minus the hole for the shaft, f'course)

Don't know what this means for our torque-discussion, though. Just an observation.

The only way would be a direct dyno comparison. Same KV Neu versus same KV Lehner (similar size/weight, too)
