Discussion about cogging

you’re ignoring that momentum is also gained equally… during the first portion of cogging, the motor slows down, during the second part it speeds up without any outside force. result? net 0 loss.

that’s entirely separate from the overall conversion of momentum to heat which is an entirely separate phenomenon unrelated to the cogging.

Then why do I not coast like regular wheel? The one thing known is it’s not net zero

because of the eddy currents

Haaaa. Again. I’m laughing. Where u see eddies like that.

any time a magnet passes a conductive material

Rpm dependent

Look, my whole point is, you seem to be claiming that a motor does not coast like a regular wheel due to cogging. I’m saying it’s because this:

AKA you’re moving magnets past conductive shit. Look at the amount of resistance there is in that demonstration at LOW speed.

And I’m saying to u the only difference between a cogging and non cogging motor is slots. So ur copper pipe…we now have a copper pipe w slots… which gunna fall faster slots or no slots?

still the effect is enough to instantly slow the wheel whether it’s cogging or not…

Slots will fall faster because there is less material.

In fact the magnet would probably “cog” down the pipe

How u gunna have eddies that form an exponential line …now it has some freak loss at low speed, that is also superimposed on the motor torque continuously at any rpm. It has its own torque curve that’s mappable.

Right.
If it’s a motor w slots it’s analogous to the pipe w slots. Less losses. Less eddies.

@hummieee you seem unable to mentally separate two discreet phenomenon…

one effect causes the wheel to speed up and slow down while retaining all the original energy (cogging)… no net momentum loss

the other effect slows down the wheel by converting the kinetic energy to molecular vibration (heat)… which converts the spinning motion to vibration, thence to infrared photon energy…

removing the first effect has no effect on the overall efficiency or the second effect.

So you’re saying a motor without slots won’t cog and a motor with slots does?

And a motor with slots will have less eddy current loss and less drag than a smooth stator with no cogging but more drag.

100% agree.

If ur gunns talk like that. U seem incapable of understanding this isn’t the case.

let’s me see

it is the case…

cogging

^i simply place the motor at the potential peak and let go and it spontaneously accelerates… until conversion of kinetic energy to eddy currents, to heat, to infrared radiation causes the motor to stop

No slot no cog
Makes sense less eddies w slots. Less material there. Like ur tube slots

You’re again proving my point that cogging is not the source of the resistance, but eddy current. A pipe with slots will have less eddy current and thus the magnet falls faster but cogs.

Whatever dude, thanks for playing.
