Need Help with Wiring of AC Drill Motor
Hello all,
I've been struggling with this and hoped someone could help me. I am trying to re-purpose an AC drill motor to raise and lower a cabinet (5lbs). I basically want to turn it into a winch.
I am having a very hard time with the wiring, however. As you can see in the attached diagram, there is a switch that reverses direction of the motor, sending the opposite polarity to the appropriate brush. One pole send it to AB and CD, where the other pole sends to AC and BD.
What I would love to have is a switch that, when flipped in one direction will lower the cabinet and will raise the cabinet in the other direction. I would also like to have limit switches in place to control the range of motion.
As you can imagine, the reason I am asking is because I am a novice and struggling to learn all that is needed. Eventually, I would like to hook it up to an arduino or RPi to control the cabinet via a web gui. But that is out of scope for my current stage.
Any help would be GREATLY appreciated.
Thanks!

Welcome to the forums.
Although a drill will work for what you are trying to do it's a bit excessive. You would need to come up with some type of mechanical interface. It can be used and the circuitry including end stops could be built but there is a better choice to do what you want to do. It's called a linear actuator.
A linear actuator runs on 12vdc. Smooth action, quiet and comes with built in end stops. The actuators come in multiple activation lengths. You can find them on ebay, amazon and other online stores.
In the following link is a video at you tube. It's a general intro into linear actuators. There are more videos online there including actual applications. Check it out.

Though this is not very easy but i think it can be done. I am doing a similar project to lower and raise a chicken coop door automatically using an AC Drill from Harbor Freight. Several things to consider. You will need two AC services, One to control a SPDT relay (Grainger 6CWZ1) thru your switch AC1 and the other to supply the circuits with power. To accomplish this you will also need two DPDT relays (Grainger 2W928), two limit switches, and terminal blocks. I am not an electrical engineer but i think i figured out a way to power the up and down circuits with out shorting one another out. Please look at the attached AC Drill Circuit Diagram. Over all i have about $75 in materials. I have tried and it works so far.

You've got some patience. I use linear actuators for everything. The wiring is absolutely simple.
The biggest advantage to a linear actuator is that it is highly geared down resulting in a slow powerful motion.
