Motorcycle Hub Motor Part 2

[esoneson]

I see that you say the axle is 250mm long. But what I need to know is the minimum distance between the end points of the swing arm where the axle goes through. I will be getting a Softail frame with with tail assembly that pivots on an 'axle'-like bar. I need to know of the double-wide motor will fit between the axle holding points. The real terminology slipped out of my head. Hopefully you will understand the dimension that I need. How wide does the swing arm need to be to accommodate the DU-602? There!...the right question.

As powerful as the 602 motor from EnerTrac is it really wasn't powerful enough for the 600 to 800 pound chopper Hence the DU-602 product. Its two motors locked together using one controller. The axle is 250mm long. I can get cast aluminum rim 16 to 21 inches in size any width

Eric here is the number you need

295mm 11.61 inches

LOOK's COOL MAN

Wiring it in parallel makes it a 1201 and wiring it in series would make it a 1204, right? You could use your relayes to shift, maybe?

I just got back to upstate NY from CA. I now have 45 Thundersky 60AH, 144v worth, but it's to cold out in the barn to put them on. I also got a microcontroller chip and some ADC chips, so I have started to build a (DDB) Digital DashBoard with a (BMS). Good inside project!

I did get a 360mm tire for a E Show Chopper, was planning for a DU-602 on it. It's 14" wide, hope to start the build this summer.

OOPs series would make it a 1202, because the winding only go 1/2 way across.

Happy new year

Yes 1202/1204 but instead I think DU-603 or 1203 (now I have to think about the naming) might be better, simpler solution for mega torque motor.

Two 603 motors 136 to 144 volts, that will get your attention.

DU-602 testing

Looks Good

Sneak preview no claims the track will show its worth.

For the TTXGP race motor we developed an air cooling system for the motor. We have been working on this (on and off) for almost a year now. We can get 50CFM or more through the motor
Here are the pictures



Now it's time to get the wheel to the Catavolt Team for testing

Daaaamn !!!

Will this be the first ever hub motor at the TTXGP ?

[Martin A]

In my experience it's better to suck air through rather than trying to blow it through. i.e. ICE fan on back of radiator rather than front. Just my two pence worth.

Hope this helps

Maybe.. but sucking aire make the hub to have the air that infiltrate it on EVERY uncontroled appertures and this might be a problem with dust and sand...

If you blow air inside from controlled source with filter than the motor will be always purged wich i think it is important to keep everything inside as clean as possible.

I just love to watch leading edge technology in Action!
Great post Mark

Sure is and I hope to impress

That'S a splendid point and as I'm new to electrics not one that I had considered. Thanks for that.

Also sucking is limited to a vacuum (14.5 psi or so) where blowing can be at much higher pressure if needed. We use compressed air to cool some items in our synchrotron.

Could even add a water mist to the cooling air...

[We_Go_E_Go]

That's COOL! No I mean REALLY COOL. 4 real.

[GasBus]

hey everyone can anyone help in finding a place where i could order a custom motorcycle hub motor?

[oatnet]

Wow this just gets more and more tempting...

[liveforphysics]

Hook the leads up to a CO2 fire extinguisher nozzle before the start of the race (or put one on the bike),and get that motor in a deep-freeze on the starting line.

But that won't get it super conducting,
perhaps try some liquid helium

PS: I know copper isn't really a super conductor but I imagine its resistance would still be quite low at those sort of temperatures.

CO2 cooling! Great! Now we can have a bigger carbon footprint! (Of course every tank of gas we burn is produces several hundred pounds of CO2 so the amount one would use for cooling is actually pretty small).

This may have merit on our regular hubmotors. A small tube can bring CO2 in. Some one way flaps in the covers can let it out. Just use it when you really need to keep the motor from overheating! Like that one big hill climb!!

Sorry, back to this great motorcycle hubmotor thread...

Which are the best m/c frames to use this on? A list of good choices would be useful. Perhaps some photos of examples collected in one place.

Thanks!

Ok who's going to design a really lightweight car with two swingarms + 2 du603's at the rear driving it!

Great work Mark.

[johnhead@frontiernet.net]

Car NO but motorcycle Yes!
Thanks to Marks great motors and his excellent customer service!
