I have a simple multi voltage transformer and a dc motor. When hooking
the power supply to the motor to spin a light platform, the motor
spins too fast. What type of circuit would allow me to control
the motor speed. I tried putting a resistor in the path and got
not motion from the motor at all ( i tried multiple resistor sizes)


I also tried this unsuccessfully:


6v+

r1 = 2.2k

|------------- motor ---|ground
|
r2 = 2.2k
|
-
ground

Please help or refer me to an internet page, thank you
