TORQUE - HP*5252/RPM = 3*5252/1800 = 8.7533 ft-lb Look i am just a student and in urgent need of someone to cross check my calculations....lets say I plan to go with 3600 RPM instead of the original 1800 RPM then the NEW TORQUE = 4.3766 ft-lb.....now my question is HOW MUCH WEIGHT CAN I MOVE...

I am building an electric go kart using a DC brush motor of 3 HP and 1800 RPM.....wheel diameter is 11 inches and total weight (kart+driver) is 180 Kgs. How do i find out the torque produced? How do i find out the maximum speed? I would like to know weather I should go in for a higher RPM motor...
