* 24 volts (good) * 70 amps peak, 14 amps continuous (use a Vantec RDFR23 speedcontroller) * 15 pounds (a little heavy for lightweight, best for a middleweight) * 125 rpm (perfect) * torque 125 I/P (fine for robot purposes) * shaft diameter is 0.83 inches with double flats (the flats are useful, but the diameter is odd). * overall dimensions are 14 inches long, diameter of motor is 3 inches, and the gearbox is about 4 inches high.

This might sound stupid but whats the difference between 125 lbs per inch and 125 inches per lb ? Is it the same amount of torque? Also if there are two wheelchair motors going in the same direction on the chassis does that mean there is 250 I/P of torque in total or does the chassis only have a torque of 125 I/P?

How on earth is that possible if the people sitting on the wheelchairs weigh over 200 lbs ? Shouldn't the torque be at least 200lbs @ 6" (12" diameter wheel) ?

a.. Peak Rated Power Consumption 560Wb.. Rated Voltage DC24 Vc.. Rated Current 11.5 Ad.. Rated Torque 16.5 Nme.. Rated Speed 166 RPMf.. Efficiency at Rated Speed & Torque 52%g.. Peak Current 65 Ah.. Peak Torque (at 70A) 55.4 Nmi.. Gearbox Ratio 1/28j.. Minimum Brake Torque 2 Nmk.. Maximum Brake Release Current 0.4 Al.. Mass 6.9 kgm.. IP Rating IP50n.. Noise 65 db(A)

Shouldn't it be 125(lbs/in torque)

how do I calculate how much current the motor draws based on the weight of the robot?

Well what happens at 12V ? Is everything halved , including torque?
