I have a standup scooter, it has a 24 volt 250 watt motor.
If I buy a higher wattage motor i.e. 500 or 1000 watt motor, as long as it is 24 volt DC, it should still work, right?
 
well it depends on the sprockets of course.....


and you gatta hattle.

you should be good and doing 200+ in no time !!

:thumbup
 
not looking for speed references, 50 pages, or derogatory questions.
Before someone tries to make a funny, it's got 8/18 toothed sprockets.
I am about to make a bid on a motor I wanna know if it'll work 1st though.

Someone who know motors, it'll work right?
as long as 24v DC supplied is the same, a higher wattage motor should work right?

Just notating that for reference...should the need come up later for evidence...:Bap

1) it's too late, the first reply was a joke
2) if you want sustained top speed increase, the way to do that is sprocket change. seriously. you will accelerate less rapidly
3) if you want to double your speed for a little while then get the bigger motor. you will probably melt wiring or fry the speed controller as it's not designed to handle the increased current the motor can ask for
4) you're going to be a joke on here for as long as you choose to keep posting. either get used to it, or stop posting

Ok, thank you,
what if I upgrade to like 10 or 8 gauge wiring?

I already looked for different sprocket sizes, they don't make them:thumbdown
 
upgrading the wiring is probably just going to move the failure point. better the wires melt than the speed controller dies, you can replace the wire and go back to the old motor

Don't you get it? You don't need more power to go faster. It's just like a clock. You need to gear it properly.

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

so you think that you're going to go faster, but draw the same current without changing gearing?

i can't explain the engineering, i hated those classes. you either need more power (current drawn from batteries faster) or different gearing

oh yeah, there is probably a reason they don't go much faster than 15mph, like they get really unstable at that speed. just a guess that is

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

I have a gas powered scooter that can go 40mph, it has smaller wheels than the electric.
the electric has 10in inflated wheels with a hallowed steel frame, able to safely carry a 220lb rider, it is plenty stable for an additional 10-15mph.
The reason it isn't meant to go much faster is because it isn't meant for adults, physical adults anyway.
I am trying to "Tim Taylor" it, if anybody remembers "Home Improvement"

8 Ga. wiring should work fine for 20A. (Actually 12 Ga. should be fine too.) You'll need to redesign / rebuild the controller and you'll prolly need to redesign your power supply. Sucking out 2x the power will prolly give you ~ 1/3 the range and may overheat the batteries and reduce their lifespan considerably.
