12 kw rc motor

[HAL9000v2.0]

These motors seem to be large enough to operate as a supercharger drive motor, so the sooner I can get a proto-type, the sooner I can get fabing up some brackets and a drive system to make an E-supercharger kit with this thing. If I can make something that can perform well and reliable in the real-world, this may mean triple digit order numbers of the motor from me.

Now I see what it 8 pcs. for
Nice idea. Do you plan to go with reduction or better say multiplication gears? I use to try something similar with low pressure turbo but didn't have such machinery back then so it blows itself quite few times...
Can't wait to see results.

I've got a screw-type positive displacement internal compression supercharger laying on the floor of the tinkering room. 1.1L/revolution. RPM limit of 19,000rpm.
I figured I would throw an 11t motorcycle #520 chain sprocket on the supercharger input shaft, and a 25-30T #520 sprocket on the supercharger, make a bolt-together bracket setup. I figure I will need the voltage of 2x the safe no-load speed for the motor to not have the BEMF be decreasing the torque as RPM increases, because I need roughly flat torque, with linear power output increasing directly with RPM, so I kinda got fit motor to be running in just the up-hill starting part of the motors power curve.

It's not an easy burden for a motor, but it only needs to be thermally stable for 10-11seconds at a time, so I think it should be fine.

Get a motor in my hands and you won't have to wait as long.

Bad link?

heheh , not bad link, bad understanding .... sorry .

[markobetti]

oh yea it was bad link : http://www.akamoto.co.uk/electric-supercharger.asp this came to my mind ... but still i know it is
not what you were talking about

Nope, that electric supercharger is nothing but a gimick.

I had never seen that one before, but yes, quite a lot like that.

Or like this, except not using 3x crap brushed starter motors. lol

I love it!!!

[markobetti]

thanks man i appreciate it

The shaded background face is a bit creepy once you notice it... Well, I'm really curious about this motor and I think I'll order one when it will be available. Don't make us wait too long!!

As a side note, what controller are you guys going to use?

[markobetti]

well , i am going to use Kelly controllers , really : u can use almost anything with this motor ..so i guess it depends on your needs....or whatever you have in your backyard ...

[markobetti]

but....i only have 7 - 10 kw controller.....hm .... Others : what will u use ?

the face in the background will be changed with other face ......i want to make a more power full expression, like when Goku is going crazy Just kidding

[etard]

This is awesome!! I completely missed this thread, but put me down for one when the arrive. Also, I have only seen that one pic, does Hal or Mark have one of these in thier hands? I would like to see a pic if possible with something to scale it by. Carry on men!! EV nirvana awaits!!

Have the camera ready, then tell Hal someone has stolen his e-bike, start snapping pictures

You could use the worlds most feared face in unarmed combat.



He takes a normal face, and turns it into goo.

Nice idea, i we got to try that one

[liveforphysics]

Fedor. Destroyer of all challengers. IMHO, definately the face to use for something you want to bring world-wide respect/fear.

love the logo, love the name. looks a little like a rave-flyer-on-the-windshield circa 2000
