Recently I was working in a Solar Car design .
I had a problem in the designing of this solar car As my study is mechanical Engineering .
The problem was that the solar cells produce ( Direct current ) while all the motors i deal with work with ( Alternating current ) .This is related to ( Electrical Engineering Field )
After long day of search I found this file talking about motors work with Direct Current ( DC Motors )
I hope that i can help somebody faced the same problem . ^_^
