battery for electric motor

[kikid]

Hey guys, could someone suggest me best battery for electric motor 24v 1kW, i have 2 bateries from electric drill each of them has 20v and about 10A, could they maybe drive that electric motor, i dont have any car batteries so if anyone knows what othe battery i could use please tell me, i dont need big capacity but Just battery with enough energy to drive it on max speed

you need atleast 15Ahr batteries I would say

Capacity of battery isnt important for me now i just want to know would 2 batteries from electric drill have enough power to drive 24v electromotor on maximum speed

if your batteries are 20V, then you only have two possibilities... powering the motor at 20V or 40V... not sure how you would power it at 24V without a complicated controller to limit the voltage...

That motor is going to draw over 40A on take off... dont think your drill batteries are going to handle that very well....

just saying...

the drill batteries will most likely have an overload protection and just cut off on the first try.

cheap ones do not have an overvolt protection, but AFAIK overtemp protection is obligatory for tools and laptop batteries.. so they'll cut off in about 2-3 seconds..

That's under load, free revving the motor will not draw more than maybe 1-2Amps I assume so to just test the motor your batteries should be fine.

No, you need either motorbike or car batteries (or if you want to spend more money... Lithium Cells)

I just want to make simplest small car for 1 person with about 25-30kmh speed, i want to make some kind of test version to see how i will work so im not planning to spend money, and if that car would work good i would upgrade it and buy better motor, bateries etc. So can anyone suggest me which motor would be good for that

the motor is okay.. the batteries are the "no go"

Well, my 1kw motor doesnt work, i have 12v fan cooler motor from Volkswagen transporter van, its not written on it how much power it has so what do you think would that be good for kart

I would use a couple car battery's if you want to pull a lot of amps.If i remember correctly they have over 100 .

If you are referring to the motor that turns the cooling fan for the radiator, then no, it wont work. It is designed to spin blades in open air, it will not have enough torque to move a cart.

I also have motor from drill, it has 800W but it works on 220V, is it possible to make it work on car battery

 

[dcastillo]

no its not....

Okay, thanks guys for help, I'll first make kart frame, wheels, steering system and other things then i will deal with motors,and will try to find best motor for my car, im also thinking about using inside combustion engine, what do you guys say about that

Just remember that it is easier to fabricate a frame that is going to work if you know what the drivetrain is going to be. You could do the frame and then realise that the engine is too big or small for the frame you have made, etc
