i should go with? I need to use them to wind rope that will hold a load of about 30 to 50 pounds. Are these sufficient?Secondly, how can I control the motors. I am new to AC motors and not quite sure how to control them. I would like to implement a micro controller and have it be autonomous. What will I need to do such a system? (preferably as cheaply as possible. )Thanks so much!
You need a gear motor of some sort, preferably a worm drive one, or one with a brake, You don't need the second one, it needs an external gearbox, and with one can probably lift a couple hundred pounds. I'd get one a bit bigger than the first one, which has a worm drive on it, or add a worm drive to that one. To control it, you would use a pair of relays with 10A 120V contacts, and coils appropriate to your control circuit, likely 12V. One relay would power the motor CW, the other CCW, by each applying power to the lead on either side of the run capacitor. For the bigger motor, you would use a 3 phase (preferable interlocking) contactor set. One set of contacts on each section would engage power to the motor, the other two would apply the correct polarity to the start circuit (in relation to the run windings) for the intended direction.
