Hi, I am looking for a 115 VAC motor (able to be plugged into an ordinary power outlet) that is capable of raising and lowering a load of up to 150 lbs. (attached to a cable and a pulley) at the speed of 6 inches per second. I want the speed to remain constant even if the load changes. How can I turn this into motor specifications? Also, given the low speed, will I need to use a gearbox with this motor and if so what could I use? Also anyone who could help me out in selecting/recommending parts for this system I would be eternally grateful. Thanks for any help.
