I stared with my own DIY water cooling. Its goes well but i got stuck on the pump. Yes i could go in store and buy aquarium pump but it just wouldnt be so fun. So i have a motor i got from air pump which was made to connect to cigarette lighter in car. I want to make it run on 12V connector on Power Supply and i need help with connecting it. All i know is that motor is 12V. I searched internet and so and i cant find more about it. Please tell me how to connect it (with resistors and stuff) if you would have any idea how.
While you can use a 12V DC motor if you have a very good PSU, I don't recommend using an air pump for circulating liquid.
Yes but can i connect 12V motor which is meant for 15A on 30A 12V connector?
I totaly agree. Using air pump would be stupid. But never intended to do that. I just took the motor out of there. I have whole construction made other way. If you want i can show you pics when I'm done. Hope it will be soon.
You are trying to use an DC motor from an air compressor then? If so, you will be better served by a separate DC power supply, as these motors have a very high inrush current and the PSU most likely will activate its current protections (in steady pace, the motor will take 5-8 Amps, but it starts at over 50 Amps).
