Cogging happens and with a hub motor there’s a loss of roll let’s say. U roll ur motor vs regular skate wheel and u know it isn’t going as far
yes whether there’s cogging or not, because of eddy currents

Why do you keep associating cogging with the resistance from a motor. It’s 2 separate things. Just because you feel notching when you hand spin a motor doesn’t mean that it is what causes you to slow down.

@hummieee how do you explain why the motor spontaneously accelerates when i place it at certain locations in the rotation and let go
Comparing the pipe w slots vs not… drop magnet and it losses more energy, goes slower, with no slots, Forget cogging for a min just eddies.
don’t ignore this question
It doesn’t return back fully what is lost. Otherwise it would roll as well as skate wheel. It doesn’t
and where did the energy come from to make it spring forward (or back… doesn’t matter which)
Again why do you keep thinking that the cogging is what causes resistance?
fact is it’s not all coming back.
that’s not what i asked… answer the question:
Okay need a regroup here.
-
Can we first all agree, that from the law of conservation of energy, all momentum loss is converted to heat here.
-
Figure out what phenomenon is causing the heat conversion?
hummie admits the motor that cogs “springs” forward… but where does the energy come from? @hummieee
a motor that doesn’t cog doesn’t “spring” forward, does it? @hummieee
Where did it go?
Imagine this. 2 magnets facing opposite of each other in a plastic tube. 1 magnet is stationary, another magnet is dropped on top so it bounces off the 1st magnet. This bouncing is “cogging”. If these 2 magnets are in a vacuum with no air resistance, what will cause these 2 magnets to stop bouncing?
Ya really need to come in all hostile like that? What you think I’m personally attacking hummie? I’m literally just stating well known laws that anybody can go and google up.

in order to bounce they have to be constrained to one axis of freedom, and in order for that to happen there has to be friction which converts to heat (and likely eddy currents, which convert to molecular vibration, which convert to infrared photon energy, which escape the system)
It was a theoretical that they magically stayed in axis. And you’re right, the 2 magnets would only induce eddy current in each other.
…[crickets chirp… @hummieee stumped by last series of questions]…
That was be being nice goose, if I was hostile you would know it.

Or just ignoring your bullshit, that’s what I’m guessing.
