[HomeBrew] Motor speed control

[Loren Moline WA7SKT]

Hello,

Does anyone have a ready designed circuit to control the speed of a DC 
motor. I need something of the variable frequency or pulse width or both. 
Lowering voltage reduces speed but also power. I need fine speed control of 
my dish positioner.
