Brushless motorcycle motor

[spectrospirit]

I'm going to make my own brushless, my first magnet have arrived at my place, it can lift 60 kilograms and hopefully repell just as much.

It's gonna be mounted on the inside of the wheel and the wheel should be hubless.

Going to order 3 more of these ;)

No batteries will be needed as the magnets create its own electricity due to the reaction created by its magnetic field.

I need parts and the tools, then i'm ready to head in to the future with my own hands =P.

It's gonna be a blast ^^

since these are losing their capacity, have you looked at a123 cells? They are supposed to have a longer life cycle.

[jonnyasprin]

wow that things quiet.

[mikedrazen]

very cool, nice e bike, really

[circuitdotlt]

OMG, batteries losing their capacity after only ~100 cycles (I guess ~60 miles per charge)? Thats a failure...

[otherrobots]

How do you have the Phase and Hall sensors wired from the motor to the controller? I have a kelly controller and brushless etek.

Mine is:Hall Control to Motor A=W, B=V, C=U. Phase to motor A=B,B=G,C=W.

Also, does the video show FULL acceleration?

[Zeropointbug]

I am not clear on what specs you are running... I am researching electric bike parts, I like this motor and might use it, can you answer a few questions?

-What brand battery? Type? -Series cells and how many parallel?

-What controller?

-At 48volts, the motor is capable of 7hp, how do you not have enough power at 75volts, should be a rocket... are you using low quality battery cells?

Thanks.

@Zeropointbug

Sony 26650VT Cells. Rated as 3.2 AH and 20C. I have 18 in series and 12 Parallel.

It is a Kelly Brushless 72 volt 200 amp controller

I have enough power. I now have over 6000 miles on it and the cells are starting to loose capacity. I use it as my daily commuter to work 8.5 miles. I run it at about 45 MPh and am quite happy with it. If the cells get to the point that I can't make it to work I will replace with Lipo from Hobby King

[DanFrederiksen]

too much motor for a bike :)

my dc etek wastes a lot of energy running idle which is terrible. how much does that one use to just spin?

for instance to maintain 3000rpm with no load. and how well does it keep spinning if you just spin it by hand?

[drewjet1]

@DanFrederiksen

I don't recall the exact amps but seams like around 4 amps at full throttle

[frosty9595]

Lead acid or lithium ion batterys?

[drewjet1]

@frosty9595

Lithium sony cells 18S12P

nice job keep up the good work.electric vehicals can be so much more powerfull that gas.i go look at the electric datsun racing for some laughs it blows everything away in the 1/4 mile.if guys can do this in their garage why cant vehical makers do it?oh i forgot oil companies dont like it hahaha those dirty thugs.

have u seen the 59 lincoln neil young is converting to electric?instead of plugging it in to recharge it you plug it in to power your house.check it out@lincvolt.

have fun!!!

[Dan19842505]

What is the cruse speed? and what s the motor?

[drewjet1]

Sorry for the delay, haven't checked in in a while...too busy riding.

Top speed right now is geared for about 48 MPH, I have had it geared for faster, around 55, but prefer the acceleration at this gearing, range is around 15 miles. Charges in 2 to 3 hours.

[Alexvideoclip]

This will be a revolution.

[chimaira1001]

lol it looked like a rc bike 4 a sce lol.

[Carlsarv]

Wow that is sexy!!!

[javiermad34]

Very interesting.... I'm looking fot Kelly users

[santimeier]

Hi Drewjet. I'm building a similar bike on a Xr250 frame. I use 5 12v33Ah AGM (60 volts) batts instead of lithium however. I think my kelly controller is damaged too. I expect to hit peaks of 300 amps...the bike feels like a moped!

[drewjet1]

The Kelly is working well. I had 2 that failed, but they covered them under warranty. So far I have about 200 miles on it and am very happy.

I am running 75 Volts and hitting peaks of 150 amps.

[DarkOnyx]

This is fantastic. I am building one myself with a Mars brushless and a Kelly KBL 48301 controller at 48 volts. I am glad to know that the Kelly controllers work, there seems to be a lot of uncertainty about them from the web research I did.

I was considering a Sevcon Millipak PMAC controller... but 250 amps peak is weak sauce.

[aproldan]

how's that kelly controller working out.. i've been hesitant in getting one because they are still kind of new... my dirt bike setup is 3hp@36volts with a 24-28volt 300amp altrax controller.. i topped out @ 49.9 running it @48volts right now i have it set @35mph @36volts ..keep up the good work

[drewjet1]

About 3 hours to charge, I am still working on my setup. When I have it presentable I will post it.

[drewjet1]

I got about 20 miles the other day and was right near the end of the charge, actually pushed them harder than I wanted to. However I am just tapping the first 6 cells for 24 volt power to run controller and lights, so once I put in a separate battery for that it should extend me a few more miles.

[evmotorcycle]

What's your distance now Drewjet? How long to charge?

[drewjet1]

It is the Kelly 300 amp w/ regen

[lutach]

What controller are you using?
