Cheap computer fan speed controller used to slow the speed of a DC motor? Answered
I've got a cheap 12 VDC computer fan speed controller (adjusts from 5v to 12v) rated at 1000mA. It's designed to be plugged into a computer motherboard with a 4 wire plug.(green, yellow, black, and blue). It also has an output socket for a fan...looks like 3 wire. I'd like to provide the input of the speed controller with a 2 wire (+ and -) 12VDC, 3A power supply that plugs into a wall socket (110 VAC). I'd like to then use the output socket on the controller to power a 2 wire (+ and -) 12VDC motor (rated at .03A) in order to change its speed. Is this even possible? Is the controller considered a PWM controller? The instructions on the controller says the blue wire is the "control" wire. How would I wire up these components? (110VAC 12VDC power supply, 5v to 12VDC fan speed controller, 12VDC motor).
