... dare ... Unsprung weight becomes a factor when the ratio of unsprung to sprung weight gets too large. So the heavier your car is, the heavier you can make...
Thanks for the feedback Ryan. This unit is indeed going to be heavy. Saving weight will need to be a consideration down the road for sure. Right now we'd be...

Hi Guys! Well I'm working since quite a long time on a brushless outrunner generator project. I've succeed to solve a lot of "issues" concerning this project...
If you are testing without a load, all the energy generated is dissipated as heat and burn the coils. Attached to a large resistor (or discharged battery), the...
Hi Rick Not exactly. Without a load, the losses are only iron losses (copper losses are zero) The corresponding heat is generated inside the laminations (eddy...
Hi Hadrien IMHO If you desire 60W under 12V you need 5A But 5A and internal resistance 4.2 ohm means 21 V .. That is not compatible. Your windings are too much...
... Something seems wrong. I calculate you'd need 3 parallel wires each 40m long to get 4 ohms resistance. As others have pointed out, you need to lower the...
Hi all! First thanks a lot for your time :-) When I've said "under load" I meant that the generator was connected to a batterie and charging... :-) sorry for...
Hi, Well... I've never thought about it.. Won't have any problem to linearize it? As soon as my target is DC... well I do not know... best regards, hadrien ......
Hi, well my generator is about 50mm ext diameter... for 60mm long... But I still don't really understand how it's working... How look the output? is it DC?...
Dear Hadrien, I have build a generator with permanent magnets and I did the following things to make it work. To determine the number of windings I made a...
I haven't tried this but to me it seems that you could make a better generator by having strong magnets and a field weakener to cut down the cogging at very...
Hi Hadrien There are several ways to minimize cogging in an outrunner alternator (generator), without affecting the output/efficiency too much. Rounding the...

Hi all! I'm back... I've founded some new information and I think it would be good to share them with you. There is a table called AWG (american Wire Gauge)...
