Hello, I am working on a design, and I am having trouble selecting a motor. I will be able to supply 1.2 A and 12VDC, and I need the motor to be able to move a load of 0.5 lbs at 500 rpm. So far, I tried calculating torque (based on F=ma and T=Fr, r=1.06 in in this case). Then I used HP= (T*omega)/5252 to get a required Horsepower of 0.5. But I feel like this is wrong. Any advice would be greatly appreciated!
