Converting mains power to battery power? Answered

I have plans on building an electric go cart, however, the only motor I currently have is mains powered, as such I was wondering if anyone knew of any ways to convert mains powers to battery power, hopefully car batteries as these would be what I using. I've searched high and low and can't seem to find anyone that has done this, let alone a tutorial. Anyone with any idea's or links would be very helpful. Thanks in advance.

you usually can't just directly convert an AC motor to run on DC - sadly it just wont work like that.

What you can do is run a battery powered inverter that will create the ac power you need - try searching for 'ac motor controller' or the likes...

How about the idea in this instructable? I'm planning on running it on high voltage anyway, so I was wondering what the disadvantages to doing it this way would be?

Is your motor the right type for that? You'd be better off getting a DC motor I think, but I guess you have the 240VAC motor so that's why you want to use it. L

It looks like the right type, it's out of a jigsaw. When I get the chance I'll go see if it has anything to do with what voltage can be used on it. From what I've read most power tools seem to run universal motors so hopefully mine is. Thanks for the help.

Also, I live in the UK and so mains power is 240v and not 110v if that makes any difference.
