I have a project that I need help picking a motor/controller for. I have a jack that will lift a 300 pound load up and down. It requires about 8 ft. Lbs. of torque to rotate the hex bolt on the jack. I know it needs to rotate 20 revolutions to fully extend up. I'd like to add a motor that can be controlled to rotate the jack up. Then bring it back down. But as it comes back down it knows to automatically turn off. Also if it could automatically slow down as it approaches the lower end so it doesn't slam the load to the floor that would be a bonus. Any ideas? It sounds like I might need to program a controller that will operate it by the touch of a button to power the motor for 20 revolutions. Then when it comes back down to be programmed to vary the speed such that is gradually decreases as it reaches the bottom. I didn't know if there would be any off the shelf motors and controllers that might work for this. Thanks.
Also my power source is a 120 V AC.
