Kids go-kart from washing machine motor
James - 20/1/15 at 12:05 PM

Just had to replace a hardly used 3-year old washing machine due to a circuit board problem.

I know little about karting and even less about electric motors but I was wondering if it would be worth keeping the motor to build a kiddies electric go-kart from?

I've seen one driven by an old battery powered drill so my suspicion is a washing machine motor would be more than powerful enough.

Cheers,
James

Just realised this is a completely retarded question as the motor is presumably 240v.


Ah well! Carry on dreaming then!

you just need a long extension lead! then if they get out of control you just 'pull the plug'

Suitcase generator on a trailer? It would have more range then your average 12v go cart!

Probably more useful to use the motor as a wind turbine?

Use a 240v generator and you've made a hybrid go kart!

That's what I have done......

How about one of those power inverters that provide 'mains'power from a car socket?

You need to find out what type of motor it is.

I had a washing machine motor that I thought of using as a machine tool of some sort.
Now in the bin. It was a brushed type with a lot of wires coming out of it.
I could of rewound it to run on lower voltage, but that was never going to happen, too many other things going on.

Some motor are 3 phase brushless types. Had the idea of using one on a small lathe or milling machine.

Maybe you are looking at it the wrong way! Get rid of all the dodgy electrics and put a bike engine in the washing machine!

13000 rpm spin speed would get your laundry dry!

And smelling nice it its a 2 stroke!


Mmmmmmm rock oil.....

I am sure i remember from physics at school that certain types of brushed AC motors run quite happily on DC too (as long as you can sort the wiring).

You can't do it with induction motors or anythign so it will depend on what type you have.

I would imagine you would either be very short on power or pulling much current than the motor windings are comfortable with. Fit a big fuse!

Googling DC washing machine motor returns some info certainly.

Ideally you should find a Sinclair C5 motor and use that in the kiddie car - but they're as rare as hen's teeth nowadays, and go for stupid money as they're so useful and powerful...

The swing bin racer that I would like to build for my daughter if she shows any interest uses an 18V drill.

My 1/8 RC has a 1350w motor at 14.8V which i reckon should propel a childs toy quite nicely!

IIRC these were converted washing machine motors - so that's a full circle!

They were made by Electrolux!

I smell a business opportunity for someone!

Made by Hoover I think?

They are called "universal" motors, and are the ones with series connected field coils rather than permanent magnets. However, without rewinding the motor the voltage requirements will be still be similar (i.e. a 240v AC universal motor won't be very useful when connected to a 12v battery).

I have 2 x wheelchair motors in my loft. 24v and bags of torque for exactly this reason.

Before you all ask, NO

We're both wrong! Just looked it up, and found this:

quote:

The C5 motor is a 12v DC permanent magnet motor, rated at 250W continuous. The motor was made by Polymotor in Italy, part of the giant Philips group. While it is true that Polymotor make motors for washing machines, it is also true that they make torpedo motors! Perhaps it would have sounded better if the C5 was powered by a torpedo motor! Being a 12v DC motor, it is far removed from the AC motor used in a washing machine anyway.
