DC to AC convertor

[Archangel]

Hi, I have a 1.5/2W 6V AC motor and i need to run it from 12V DC. I know DC to AC convertors exist but the ones ive seen usually deal with 240V. I can regulate the voltage down to 6V DC but i need a component that will convert the DC to AC. Do simple, small convertors like this exist and are they expensive? Ive already searched but i only found the high power ones.

I am pretty sure you could build one. I used to see circuits for these, often in the electronics magazines, used a 12v ct pri and 6v secondary transformer, a couple of transistors . . called it a multivibrator, I think. Base of Q1 took signal from collector of Q2 and vice versa.
