hi everyone,I'm a beginner in electronics and have been learning my way through forums.
I have a 5v DC 0.6 A power supply .
I need to use this to get a voltage somewhere in the range of 0.5 - 1 V which i intend to use to run a 5.9V dc motor at extremely low speeds.
The dc motor I have is scavenged from an optical pickup of a cd player which i broke up from my old cd player and i dont know much of its specifications except that it is a 5.9 V dc motor .Also I tried varying the voltage using a lab power supply unit and i observed that the motor speed increases on increasing the voltage.I hope this helps to determine the type of the motor.
I tried using 100 k pot connected to the centre tap of a voltage divider to reduce the voltage.But the current i got was too low to run the motor.
I got a current of 0.5 mA at 0.6 V.As i said,this wasnt enough to run the motor.
I need atleast 100 mA of current to be on the safer side.The motor usually starts working at a current of .05 A.Also another requirement i have is that i need a very fine handle to vary the voltage, something that would give a resolution of .01 or .001 V.
Thanks in advance
