It sounds like you have a DC motor and you need to control the speed (at 10 RPM) while maintaining torque and you need to use a microcontroller to do it. Typically, this is done by using pulse width modulation (PWM). This can be done with a 555 timer like this or done with a microcontroller. A Stamp or Propeller can do this. It would help to know the current needed by the motor and the voltage you plan to use for the motor. Do you have any way of sensing the motor speed? How do you plan to adjust the motor speed?

Here is a YouTube link for an AC motor speed control for use with an Arduino. It would also work with a Propeller. There is a link on the YouTube page to the PCB layout and software.
Here's another link for an AC motor speed controller using an 8051 microcontroller.
