how to rotate a motor at very slow speed

[AVIJIT DAS]

I want to rotate a belt-coupled pulley at a very slow speed, like 10 rpm. Vibration should be as less as possible. That may occur if I use stepper motor driven by microcontroller.  Tried with geared DC motor with PWM control, but rotation is not smooth. What is the best choice of type of motor or control method for very low rpm and vibration less operation ? Give me idea please.

there are DC gear motor available from as low as 1 RPM also

Here is a link of circuit diagram and With Live demo video of DC motor speed controller . This works on pwm, can easyly used for 1A motor. Very Smoothly .  Tested on 12v 1A DC Fan

DC Motor speed controller using PWM. very smoothly and noise free. tested on 12v 1 A DC Fan.
