Golden HPM5000B

[esoria]

Hallo boys new project start, yesterday we create new frame for a Golden HPM5000b motor,with a kelly kbl 150A phase controller, and A123 120V cells...
The ratio gear is 12pinion 46ring on a 16" scooter wheel

Ok the bike seems go very good,but i imagine alot more power on this motor, the bike with no load make 100kmh, and on the road 100kmh too!! Seems gear is very low, because go at the same speed load-no load, Kelly controller 150A(phase) sometimes cut-out power, maybe because too much load from motor? I need more big controller? How many amp i can put inside this motor? 300A phase?
Seems this motor go at 3800rpm, not very fast, maybe i need increase pinion for go more fast, i have 12tooth now, i want put 16tooth but i don't know if motor can pull this ratio...
I think i have good chance to pull 16pinion because with 12 pinion i go on the road at the same speed on no-load...
The bike weight 50KG, and maybe is for this weight the performance is not very funny

Super super cool!

[esoria]

Thanks
Boys i want to make scream this motor, but i don't know how much power i can put inside, 300-400A phase?
Gear ratio? Now i have 12-46, i want to try 16-46 for go at 140kmh no load, i hope motor have enough torque for push this gearing

[neptronix]

140kmh? That's asking way too much of the motor. Remember, you've got the 1/2 size version of what liveforphysics has, and the last time i checked, he hits about 130kmh ( 80mph? ).

You need to design it for a much lower speed. Unless you want to sell this motor and get the 10kW version

[esoria]

mmm lower speed no good
I go already at more than 120kmh with my greyborg motor, i buy golden for have more, not less!
I think i can gear up, because i can go at the same speed on the road, that no load speed now (100kmh)
I think i have enough torque for gear up if my load-noload speed is the same...no?

I'm amazed you can go that fast with the greyborg motor. To maintain that speed, you need >10000w continuous.
If you can do 10000w on the golden motor unit, i don't think you will be able to do it for very long.

Make sure you have a temp sensor installed. It's possible that i could be wrong

[esoria]

i hit 120kmh on greyborg for few second, i drive greyborg with 120V*150A=18KW
Sure my bike with greyborg is very very light, this bike with Golden is alot more heavy
If this Golden is really 5kw continous, i can put for few second 20kw inside, i hope...

[nechaus]

iv got that motor, mines the 72 volt version
iv got a 150 amp controller doing 300 phase amps,
but im beefying mine up to 500 phase amps and 250 battery amps


The motor will run slightly warm doing regular 10kw peaks ( 30 degrees Celsius on the case ) , its like nothing compared to how hot i run my hub motors...

This motor with this small as 12 inch wheel geat ratio of 11 tooth motor sprocket and 52 tooth on the rear wheel, gives me a 70 kmh top speed.., i did a burn out on the grass that was over 100 meters long!!!!!!
its a great motor and i think it certainly can be geared for high speed with that bike but i do think you should get a bigger rear sprocket and gear it for less to run it more efficiently


I like your bike build im about to re build my bike you see in the video. it was slapped together in under a few hours, just wanted to really test out the motor.

This motor Will eat the greyborg hub motor alive... and do it with a lot less heat
I reckon you could put 20 kw into it for 30 seconds atleast, A big long fat burn out on the road

A bit more actually

"....It's extremely fast 0-60mph, and tops out around 100ish mph."

Again, that motor Luke has is double the size of the HPM5000B. It's the 10kW version, weighs something like 44lbs and he's putting >40kW peak into it.

[neptronix]

But the half size version still kicks ass. It's basically a brushless eTek/Mars clone.

But i've never heard anyone who put together an eBike with a hpm5000b/etek sized motor complain about the power, lol. I read a few instances where some people thought it was too fast and sold off the components.

[Byte]

Awesome!

[nechaus]

do all the eteks have an inbuilt fan?
The fan on the hpm does a real nice job, but it can be modified to work better

Going off all the pics i've seen, that's part of the design of the etek/mars/motenergy style motors.

[esoria]

The power is never enough :-D:-D
I want to try more amp inside and taller gearing...
Video soon

[nechaus]

I am getting a 15 tooth motor sprocket to 52 tooth rear wheel sprocket on mine, from, 11 tooth to 52 tooth..

It can def handle faster speeds than what im doing with mine atm.

That gearing might be perfect for my golden as I'm running a 26" wheel. What does the driven sprocket mount to and what kind of chain are you running?

My dreams of having a single stage belt reduction are pretty much on deaths door after all the years gone by thinking someone was eventually start producing large belt pulleys, or something would be found that could be modified to work.

Golden eagle has a great belt drive system where the pulley clips right onto the spokes http://www.bikeengines.com/orderpage2.htm but it is more appropriate for a lower power bike.

Have you considered getting a hold of a Zero Motorcycles 'replacement' pulley set meant for the XU/DS/S model: 25/28T > 132T 8mm Polychain GT Carbon?



or for the 2008 Buell 1125R

[nechaus]

im using #41 chain and holy mother it has stretched about 5 cm.
Id love to use a belt drive setup, i do like the sound of a chain tho.

Im thinking when i do a Motorbike e conversion ill use twin belt and motor
Ill be using twin 5000b's for a 250 cc style conversion or possible a 10kw version water cooled...

Not sure yet but ill have both versions of the motor soon, i just need to find a good controller to run these bigger motors..

I blew up a GM Controller 150 amp 300 phase amp 90 volt
Im now using a small kelly @ 105 volt 10 kw
Ill see if it blows up or not and report back.

( i have a 250 amp 500 phase amp GM controller coming) wish i didnt get that now and just got a sevcon to start with.


No point in cheaping out on controller with this motor it will just cost you more in the long run if they possibly blow up.

Iv wasted $500 so far, lucky i have the kelly on hand, but maybe the other gm controller will blow, i hope not.
Could of got a nice as sevcon.

I just bought a sevcon gen 4 for my go kart conversion. I am buying the software and USB - CAN interface next month for my netbook. I live in Toowoomba, you live in Bris no? I might think about lending to people within Aus when I get it up and running.

[nechaus]

Hey, if you were interested ill give you my number, i might just go and buy a sevcon then, i could pay you a rental fee and burrow your programming equipment...

for now i have taken a quick video with my bike @ 105 volts, hpm, kelly controller so i could only hit the throttle slowly as it would cut out with this smaller controller
but it managed to reach 123 amps

[nechaus]

if i get the controller, can i just get the handheld calibrator to use on the go when i ride my ebike,

for e.g. if i want to impress someone i can tune it to 20 kw. when i want to ride normally run it at 10kw

Well I haven't bought the programming equipment just yet. Most likely next month. I will probably try and document the progress in my build thread.
