circuit said:Yes, high magnetic leakage and strong cogging is a little concerning...
I'm afraid that doesn't help you avoid eddy currents. The lower the resistance, the greater the losses....Jordan.1 said:@Karolis im using aluminum so its not magnetic.
Jordan.1 said:Yeah but i dont see the point..? The whole frame ist made out of metal, the mounting plates -of course- aswell.
why should there be a problem then? eddy currents are everywhere but for me, theres no real problem or am i seeing this wrong?
Karolis said:I don't know if you can can call this a small leakage. You can almost lift motor from the ground (weight about 8Kg) buy putting some metal on its rotor surface.

WTF!
the revolt is more of a lower pole motor and has wide magnets. wide magnets require THICK back iron for optimal strength. thick back iron is heavy which is a big downside of such low pole count motors.
frankly speaking, after i have seen the vague performace graphs of these revolt motors, i was afraid that they have design flaws, but what would one expect from such rather cheap stuff?
edit:
there is a post with pics of the rotor where its clearly to see the wall thickness of the bell is much to thin for those magnets:

And what do you guys think about energy recuperation with that motor? I've planned a 3-4:1 gearing so the motor would spin quite fast even at low speed
why should your choice of controllers be limited? you can buy/use any controller you want to? being located in austria, i ordered controllers from all over the world, us, china, australia, germany and i bought them in austria. but this was in the very beginning, and it had the worst price/performance ratio.Jordan.1 said:@spinningmagnets
What kind of controller do you all use? I'm here in Germany, we don't have much choice with the controller. I will use an 18 fet for my build, its a infineon style controller, so I can programm it. But the only regen available is from soft to medium to hard, there's no variable. Are there possibilities to do that with some special trick, or can the Cycle analyst V3 do this?

look for kelly, sabvoton or lebowski's controllers.
to answer your ca-v3 question: NO. that's not possible. the controller needs to do that. the CA can only limit/adjust the throttle signal not the regen signal.
Cause i want to geht some warranty
