Re: K35 rating [Was: PCC controller video]

That 100hp rating for motors is the continuous rating. Short time overloading would see a motor that size putting out up to 150hp for brief time periods, with the resultant high current draw, which a controller in good condition could cope with.

I was guessing when I mentioned 2 X 65 hp for a K35, 2 X 100hp makes more sense considering they we used on 4 X 40hp cars,
