There are also more elaborate speed controllers that modulate current as well as voltage. You can run it off a battery or through a "wall wart" transformer. In the RPM range you're talking about, you probably want a gear-motor, which trades some of its excess speed for torque.

There is a bunch of items in the link u sent me... can u please be more specific so i can check the motor i need?

I though this is going to be so easy task... i just need small motor to rotate at variable speed and i cannot find the answer to my quest, and its holding my project down
