I would like to know the gear ratio and the tractive effort that a trolley must achieve with the following motor specifications: Voltage: 600 voltsSpeed: 1750 to 2300 RPMCurrent: 84 AmpsRated Power: 50-55 HP What percentage should be considered for gear efficiency, and what safe margin should be applied in these calculations? The constraints for the truck trolley are as follows:Maximum Speed: 50 MPHWeight of the Car Body: 46,000 lbs (the trolley weighs approximately 44,000 lbs)Diameter wheels: 86 inchesAdditionally, I would like to know how to plot a graph of tractive effort (in grams) versus speed (in MPH).
