Question about gearmotor power
Now I have a 1/2 hp , 247 in. lb torque, ac gearmotor that bogs down
under the loads I need it for , and I need a bigger motor. I found another 1/2 hp motor that has 487 in lbs , but am not certain that the higher torque rating alone is enough. So the question is : what is the relationship between hp, torque, and actual ability to perform high-load operations ?. This is (to be) set up powering a rolling mill. It was suggested that I get a .75 or 1 hp motor , but... thanks, Dar |
