Can someone explain to me what is the difference between a DC Motor and a DC Generator device ?
From my old school day I remember that if you have current and a magnetic field then you get motion. Or if you have motion and magnetic field you get current. So basically if you have two of the parameters then you can get the third.
I ask this question because I am playing around with a brush less DC Fan that I have yanked out of a desktop PC. I want to spin the fan so that I can get current out of it. But someone told me that this is not made to generate current.
I am confused as to why the DC fan can not be used to generate current ?
It seems you need a different device if you want a DC motor and a different device if you need a DC Generator. But in my head the devices should be the same. Why is there a difference ?
Any explanation so that I can understand the differences would be appreciated.
