scooter project electrical question

[Cycle61]

Hmmm, ya, that is true.
wait a min, it shouldn't because the amps are staying the same, it is staying 24 volts, amps wouldn't be affected

Well, Ohm's law says W/E = I
(wattage devided by Voltage equals current/amperage)
so lets say I use a 500w motor, 24v battery
500/24=21a
the current equation is 250/24=10a

I think 8 gauge wiring would be plenty sufficient.
I just have to find out the max amperage some of the current equipment can handle

My gawd, a self-reproaching squid. Where's Lovedoc?

Same voltage, same amps, more wattage huh?

What kind of sprocket do you need to get more watts without more amps?

Didn't you say you did HVAC?

Even if you upgrade the wiring, you'll still probably fry the controller. Also, your battery will last only about half as long, or less, drawing twice the current. And, if the motor has the same rated RPM, then regearing is absolutely necessary. Unless you run the darn thing at 48 volts. Regearing what you've got likely won't work because they design those things so that the motor is no more powerful and needs be for the speed they intend the scooter to go and the load they intend it should carry. I wouldn't even bother. Finally, those things are unstable enough as it is. Do you really want to go into t death wobble should you somehow manage to double it's top speed. I think not. If you want to go faster, get something else that's designed to do that. Unless you just like to tinker. But expect your project to be a bottomless pit to throw your money in and a huge time suck, likely without any satisfying results. Sorry.

You need a Mr. Fusion

The short awnser: To up the power with a larger motor you would need to redesign the whole thing, wireing, controler and batteries.

As an earlier poster showed, Power (Watts) equals Current (amps) x Voltage (volts).
At the same voltage (24 volts) a higher power motor is going to pull more current (you can't get more power for free).

Sounds like the wire guage question and speed contoller component rating has been addressed, so the next question (more important) is can the battery support the higher power / current demands of the more powerful motor. At a minimum, the battery will discharge much more quickly under the higher current load (reduced range, operational time). Additionally, the battery may not be rated to provide the higher current load and could end up damaged (cell failure, etc).

IMHO if you're going to upgrade the motor, then you'll need to upgrade the battery as well (and ensure that the speed controller and wiring are rated for the current load of the new motor).

so when can we expect a picture of the turbo that you have on the scoot.

Why is this even in "General"?


With all the threads on Scooter (Vespa style) vs. Sportbike/standard/Cruiser & which is a really a "motorcycle", can't we all agree that a piece of shit electric platform scooter is NOT A FUCKING MOTOTCYCLE??

Sheezus....

you did notice who started the thread, yes?

I already looked for different sprocket sizes, they don't make them

how far did you look?

i doubt very much that the manufacturer used anything but off the shelf motors, sprockets, and chain. you just need to find the right shelf

www.mcmaster.com and a caliper* might just solve your gearing issue

*so you can figure out what kind of chain/sprockets are already there

I am going to buy another battery and run them in a paralell circuit.
I also found a sprocket, but the holes don't line up, so I am just ganna drill some new ones and should be good.
Also I think I will upgrade the batteries to 36 volts, and buy a 36v, 500w motor.
I will need a 36 volt charger though, I am going to have some splicing to do.

I am an H/VAC Technician for 1 of my jobs, yes.

I am a Building Engineer in Pleasanton for my 9-5, well, 7:30 - 4:00
I have my own H/VAC company,
and I am a bouncer at a bar in Rodeo on Friday, and Saturday nights for events they hold

 

[luckett]

Is someone ganna video the inaugural ride of this pile? This should make excellent youtube material.

Can you please provide a list of buildings you've worked on so we all know where to stay away from?

ya, the people that paid almost 1/2 price on thier repairs and now it is running within spec,
those are the houses and businesses I did

 

[luckett]

Do you think I could also make half as much income if I lowered my fees to half price? That would be sweet because I would be paying so much less in taxes!

That would be sweet because I would be paying so much less in taxes!

let me give you an example of how much I am screwing myself by going 1/2 price.
1 contactor or capacitor (commonly failed parts) - contractor price, about $5.00
your price from most contractors - around $250 = 5,000% + markup.
that is NOT including the $90 - $200+ for just diagnosing the problem.
your price through me - $100.
Also my written guarantee ensures my competence which helps bring in and keep customers.

So you think I don't make money??? in the 4 minutes of troubleshooting and the 5 minues to replace the part I make $180.
Excluding various small discounts I give bacause I'm cool like that.
I could quit H/VAC and Bouncing at the bar and I would still make in excess of $70k a year through my Engineering career.

I do h/vac becuse I like problem solving and makin people happy, as corney as that sounds.
I paid $30k for my degree and I use that know-how daily.

 

[h2v7]

you are just like the yuttt uggghhh guy.

 

[luckett]

you are just like the yuttt uggghhh guy.

No, the yut ughhh guy is pimpin' on cragislist for soup money. Mille here is obviously a high rolla yo, jackin' the bitches and slappin' the hos! I bet he washes his dishes with Cristal.

I gotta know, where'd you get an Engineering degree for $30k?

My daughter is touring colleges this week and so far, it's looking more like $30k per semester... aye carumba.
