³ phase alternator/magneto......?

I'll test ride with a multimeter, after today, and I use a variable 6-46v USB 3.0 charging module I got off Amazon on a heat sync, simply buy a USB hub at Walmart to charge 2 devices
I have some experience with regenerative charging.
On my ebike I can use my motor either for power or for regen braking. With the braking I only get about 5% of the energy spent to get moving, back in.
1000 watts is 1.3hp. So you can do some simple calculations to see if it’s even worth it.
Let’s say you want to power something that eats 100w of power. If you power it directly with no losses at all, you will need .13hp to run it. But because of the generator loss of 95% of the energy, you’d need to suck 2000w of power to generate 100w through a motor. That’s about 2.6hp. How much HP do you have available?
I would run a 12v lithium RC battery, preferably a 4s 5000-10000mah and charge it as needed.

Trying something like this may be a better option, it's a generator. It will probably need a regulator and a battery, they have been on eBay for a while but I haven't heard of anyone trying one.
Those tiny coils suck they can barely be rectified to charge a USB 2.0.....I don't want battery's to heavy
Re gear big on brushless motor Small on shaft.... I'll see if it runs better, I did have to make another Mount with a magneto cover 0_o I'm running out of magneto covers!!

^True I might do that with my next build with a bbr magneto cover, they thicker!…… this brushless motor is 2lbs or more, I think gearing is the key here, I'll fire it up when it stops raining all week.
They have billet cases and covers... RDM performance it's going to be a few years before you get everything... And $$$$ like crazy money... In theory it would be stronger and those have the most power to draw from...
You need a 4 stroke to have the torque down low the 2 stroke doesn't have... To make power... 8-10 governed hp... You can take 2+3 hp away to run some things and have enough left for something that will pull the add ons...
