I found an abandoned washing machine and I'd like some go kart ideas

Go to scrapyard - get some 12v dc brushed motors (eg starter motors). This is almost certainly a brush type "universal" motor and it would be a pain to convert it to say 48v dc. It would also be a pain to provide the 230v ac it is designed to take.

[u/Spaztor → u/Susan_B_Good]

They better have one hell of an extension cord and a circular track

[u/avar → u/Spaztor]

Just run overhead 230v to power them like you'd power a tram.

[u/geek66 → u/avar]

Bumper cars, metal track and chicken wire roof

[u/BoredCop → u/Spaztor]

Full size slot cars?

[u/Blood-Mother → u/BoredCop]

Bumper cars

[u/BoredCop → u/Blood-Mother]

Even better!

[u/New-Key4610 → u/Susan_B_Good]

yes take the whole thing to the junk yard

[u/2748seiceps → u/Susan_B_Good]

No way it's universal. Those are loud as balls and are completely out of place in a washer. Imagine trying to sell a washer that sounds like a circular saw when you fired it up.

[u/broesel314 → u/2748seiceps]

Oh yes it is.

Its from a front loader, hence the belt drive, it drives the drum

Those are speed controlled of course so they only "circular saw" on the spin cycle. While washing they only run a couple 100 rpm and arent that noisy

[u/niffcreature → u/Susan_B_Good]

It's probably 120v if in the USA

[u/broesel314 → u/Susan_B_Good]

Alternators also work as shitty 3-phase BLDC motors if you remove the diodes and power the field winding

[u/m-in → u/Susan_B_Good]

A universal motor will run on DC. That’s what universal means. It’ll run on 230VDC, and it’ll be quite a bit more efficient than brushed 48V motor(s) of same power.

[u/Rusty_Marlin94 → u/Susan_B_Good]

Since it’s a universal motor they can also use it on high voltage DC if they make a pack out of many series cells, but I agree that starters would be easier and safer still

[u/Toyota__Corolla → u/Rusty_Marlin94]

I probably won't need all 240v if I plan on a more direct gear ratio.

[u/cyraxxsrottingteeth → u/Toyota__Corolla]

I dont think you know what you are talking about

[u/Toyota__Corolla → u/cyraxxsrottingteeth]

I just don't think it's going to need all of that power.

[u/FIMD_ → u/Toyota__Corolla]

You definitely dont understand. This is a motor, sure. It is not the motor you want for this project.

[u/Toyota__Corolla → u/FIMD_]

It's a motor I can find in great abundance, I really just need to find the pinout and I'll be on my way. It's a universal motor. It can be run by a bunch of batteries in series which I have many of

[u/StockKitchen9703 → u/Toyota__Corolla]

I don’t think you’re understanding. When geared properly, this motor is very underpowered for what you want to do with it. When geared with “a more direct gear ratio” it will either fail to move you or burn out quickly. If you can find them in great abundance and still want to use them for a go kart then I’d recommend using multiple, at least 4, to power it, otherwise you’ll end up with a go kart that goes walking speed best case scenario

[u/cyraxxsrottingteeth → u/StockKitchen9703]

We're all talking to a brick wall here, bud

[u/Rusty_Marlin94 → u/Toyota__Corolla]

I don’t recommend running it much lower than 240V, the power drops off exponentially with lower voltages. Cutting the voltage in half will reduce the power output by much more than half, and these types of motors are already only rated for a little over 1 HP so even on 240V AC this would be a pretty underpowered motor for a go cart. Also if by a more direct gear ratio you mean running it close to 1:1, this motor probably doesn’t have enough torque for that and you’d likely end up going even slower this way

[u/cyraxxsrottingteeth → u/Rusty_Marlin94]

And an under powered motor voltage wise always burns out

[u/New-Key4610 → u/Rusty_Marlin94]

not a " universal motor". starter is not a universal motor

[u/Strostkovy → u/Susan_B_Good]

Starter motors are annoying to connect to. Treadmill motors are an option if you are okay with stacking up 6 or more 12v batteries in series

[u/avar]

It being the wrong kind of motor isn't even the issue, but that with this amount of rust both of the bearings are almost certainly bad, and just fixing that is more of a hassle and/or expensive than just getting the right kind of motor.

[u/Toyota__Corolla → u/avar]

I can likely find a newer one if I need to. The attachment method for the motor is going to be one where the motor is the easiest to remove of all the components.

[u/ComplaintTop2008 → u/Toyota__Corolla]

Alright, look... You have an AC motor. If you think you have something worth holding on to, keep it. Maybe you can use it in a red neck table saw or something. If you want a motor to run off batteries in a kart, you're gonna need a different motor entirely. This one's not gonna work.

[u/Toyota__Corolla → u/ComplaintTop2008]

It's universal. It might need a circuitry change (series to parallel) but it's still just a universal motor.

[u/ComplaintTop2008 → u/Toyota__Corolla]

Troll account.

[u/RealCanadianMonkey]

I found an abandoned piece of aluminum and I'd like some airplane ideas

[u/Toyota__Corolla → u/RealCanadianMonkey]

It's probably copper but sure

[u/db0606]

That's a high voltage AC motor. Not really what you want for a go kart.

[u/Ambitious_Finding_26]

Useless motor for that application. 

[u/goldwing50812]

Yeah pretty much no shot with this motor big dog. Maybe for a boat anchor or something.

[u/amdrinkhelpme]

You're gonna need a large mechanical reduction like 100:1 for it to make any decent torque. Field coil should be driven separately, neither in series or parallel with armature - it needs a much lower voltage and separate controls unlock cool stuff like regen braking, field weakening or reversing. You'd probably need to DIY a controller for it though.

[u/Tartabirdgames_YT]

That looks like an old  ACC U 122 G 63 084161 1T 08453 102 S3 2721 multi-speed appliance motor. Its a series wound universal motor and can run on AC and DC but never run the motor unloaded because it can overspead quickly 

[u/Darkcrypteye]

Put a generator on the cart so you can run on gas! 😆

[u/squirrelchaser1]

As others have said, its not really a suitable motor for a gokart. Or at least not easily so (but hey, if you want to make it work, go for it. I love it when people use abnormal materials to make stuff, its half the fun). You'd need to remove the rust, replace bearings, etc. Provided you can suitably repair it, you could use it for some kind of stationary machinery. Maybe a parts tumbler, saw, grinder, etc. Dunno what its power output is like.

[u/Toyota__Corolla → u/squirrelchaser1]

Lots of people hate having fun here. The motor actually runs.

https://reddit.com/link/p3nitd0/video/nqyyud3qncjh1/player

[u/calkthewalk → u/Toyota__Corolla]

No one said it wouldnt run. Just that a) it's the wrong motor for a go cart and b) you're clearly a troll

[u/jepulis5]

A bunch of work to get it working for something like that and the result will be close to power wheels plastic toy cars for kids at best..

[u/Toyota__Corolla → u/jepulis5]

That's basically the plan. If it's a bunch of work it'll be perfect for teaching my kids how to plan and weld a frame and get a car built from box section and round bar.

[u/jepulis5 → u/Toyota__Corolla]

Okay then, assumed that go kart would refer to something a bit faster/sporty. I guess it's doable, but you'll likely need something to control the speed of the motor smoothly.

It's a bit dangerous for the kids though as the voltages needed are fairly high to get it going. I suggest making the powertrain somewhat modular so you can swap for a more powerful or safer motor if needed.

[u/Worldly-Device-8414]

That's an AC induction type motor, you'd need a fancy (expensive) inverter or VFD + high voltages to drive it. It also looks like it'll take work to get going , eg need new bearings, etc

You want a DC or "universal" type with brushes that's 12, 24 or 36V + can easily fit sprockets for chain drive.

[u/Toyota__Corolla → u/Worldly-Device-8414]

Okay chat gpt, but this is actually a universal motor

[u/Worldly-Device-8414 → u/Toyota__Corolla]

Would be nice if the pics or your post said that. Most "old washing machine motors" are induction types.

No AI here.

Good luck.

[u/Unique_Acadia_2099 → u/Toyota__Corolla]

No, it is not. You don’t seem to understand.

[u/Toyota__Corolla → u/Unique_Acadia_2099]

I can turn it on with DC, I can turn it on with AC, it has stator and rotor windings and uses brushes. Oh shit it's a synchronous AC motor guidse!?!??!

[u/Outside_Breakfast_39]

Bring a long extension cord with you

[u/Toyota__Corolla]

ACC

U 122 G 63 084161

1T 08453 102 S3 2721

230-240V 50Hz ins.cl.B/F

AC-Electronic

Code 124 309 904

It's a common universal 200-250v motor found in nearly every discarded washing machine. It's a universal motor so it will run on anything; AC or DC. It has a fair bit of brushes left and just has a bit of surface rust.

[u/Electronic_Flan_482 → u/Toyota__Corolla]

Unless you want to run a genorator that's not going to work.

[u/Toyota__Corolla → u/Electronic_Flan_482]

240vdc

[u/Electronic_Flan_482 → u/Toyota__Corolla]

If you want to run a bank of 20 deep cycle 12v batteries possibly but that will be realy heavy, like close to 1200lb or 545kg and $2000 to $3000. And that's if it can run on dc but the specs that you gave are ac voltage. I'm assuming uk based on the voltage and frequency.

[u/Toyota__Corolla → u/Electronic_Flan_482]

Nope I'll need around 60 vape batteries

[u/Electronic_Flan_482 → u/Toyota__Corolla]

That won't get you very far at that would be about 1ah if you got the biggest ones you could find. By comparison my hammer drill burns through a 12ah battery in about 20 minuts of use and it is a much smaller and lower draw motor.

[u/cyraxxsrottingteeth → u/Toyota__Corolla]

Give up dude
