A motor will draw a certain amount of current to work, so you need a power supply that can supply more than the current the motor requires. Since we do not know how much current that the motor requires, it is not possible to say exactly what you need, other than as I already said.
Also a motor when stationary needs more current to start it moving than when it is moving. Imagine pushing a heavy cart, loaded with a few bags of sand, it will be hard to start pushing it, but once it is moving it will be easier to push, same with a motor.

Picture of motor will help, and or details of motor (we know it is 12v) Also is the motor AC or DC ? and what do you intended to do with it?

Sorry it's not strait forward as you would have hoped.

Would you hit a nail with a shoe because you don't have a hammer? of course not, then why work on anything electrical without a means of testing Click Here to buy a "tester" just because it works, does NOT mean it is safe.

simbarb1, S-E asks pertinent questions. Ther should be a rating plate stating the voltage, ac/dc/ and amperage. without that info no-one can advise.

You say it's 100w 220v, how is that 12v ?

There seems to be some confusion, do you want 220 from 12 or 12 from 220 volt?
