I want to run a 24 volt motor froma 12 volt source. Is there a way to step the voltage up so the that it can get 24 volts. I know I can give it 12 volts and it will work, just half as fast... but I don't want that. Thanks.

what is the motor for you can always run 2 batteries in series to reach 24 volts and use a charger.thats whats us in the hydraulics wolrd does

Sounds like someone clued into how a 24V satellite dish arm is WAY cheaper than a 12V linear actuator.
Sorry dude, not that I know.

And that's the bottom line, cuz:

I newer saw anything like that in the kit or box, that converts 12V to 24V, but I am sure, that it can be done. Basically you need transformer to build up voltage. Transformers can lower or higher Voltage. I know that you can buy 24V to 12V converter, and if inside are just coils it should work in opposite way too (JMO).

A transformer can only step up (or down) alternating current (AC). They do nothing with DC.

Oups. I am wrong! Dukk is right. I forgot, that transformers work only with AC.

Then the only way is to do it with some transistors etc.

Yes, I believe a voltage doubling circuit could do so.. However, I'm not sure on the actual construction.. I think its two caps in series with one inductor in parralel, but lets see if Tech Man responds, and I'll look it up in the meanwhile.

You could always build a small switching suppply to run a 2:1 transformer, then rectify the output voltage down to whatever you want it to be. Of course, by the time you've done this, that cheap motor just turned into the more expensive one built for 12V.....

STILL waiting to hear a GOOD pair of HLCD's!!

If it dont fit, force it... if it breaks, it needed to be replaced anyway...

How much current do you need for the motor, is it big or small. DC-DC supplies can be built pretty inexpensively but it all depends. Let me know what the current capabilities need to be and I will do my best to help you out.
