I just wanted to know if the CIM motor could be hooked to the wall outlet natively or if something could be rigged to run the CIM motor from a regular 120V AC 20A household electrical outlet?
I’m planning to invest in some CIMs for a home made project.
No!
And a power supply to provide 12v DC at enough current to do something useful with the motors, will be kind of expensive.
When you ask a question like this, it helps to provide a lot more info about what exactly you want to do, so others here can help you figure out some other possible ways to do it…
A CIM motor is rated for 12V DC (direct current). Electrical mains voltage is 60Hz 120V AC (alternating current).
To run a 12V DC motor off of 120V AC mains, you’d need an electrical transformer/power supply to both convert alternating current to direct current and to step down the voltage from 120V to 12V.
The stall current of a single CIM motor is 133 amps at 12v, which means it’s using 1596 Watts of electrical power (but at this point is outputting zero watts of useful mechanical power, at the expense of becoming an excellent space heater). This means the power supply you choose to run the CIM motor must be capable of sinking at least 1596 Watts of output power. Buying a 120VAC->12VDC power supply capable of outputting at least 1596W will put a several hundred dollar dent into your wallet.
Can’t you put an circuit breaker in between the DC converter and the CIM?
No, but you could use a battery from a car, motorcycle, lawn tractor, golf cart, or boat. Or you could visit several HVAC shops in your area and ask if they would allow you to salvage blower motors from some junk furnaces. They run on house current.

I don’t follow what the point of that would be.
If the circuit breaks at 40 amps, you wouldn’t need a AC-DC converter that could output 1600 watts.
I have run a CIM from a high quality 500W computer power supply. You need to look at the specs though, as most computer power supplies provide more current on the 5V side than on the 12V side.
Well what I planned to do was use 4 similar motors to drive a winch of sorts, that would lift my LCD TV up and down a stationary pole that I have in my room.
I asked around and found that the CIM’s would lift the appropriate 25 pounds that my TV and 4 CIM’s weigh. The only problem is, I don’t want to have a car battery sitting at the foot of my bed.
Is there another electric motor that I can cluster together to lift the 20 pounds of my TV and 3 others of itself just running from 120V AC current?
EDIT: I also plan to control them with DPDT switches and would like to know if this (http://www.radioshack.com/product/index.jsp?productId=2062516&numProdsPerPage=60&y=10&x=13&retainProdsInSession=1) is the right switch for the job.
EDIT2: I also plan to wrap the whole controller in a project box so I’ll need some tips on soldering the wire to a power cord.
how are you attaching this TV to the pole and what kind of pole is it?
Also, is this worth the cost of 4 of any decent motors? why not use pulleys and a cleat from a flagpole?
EDIT:to solder a wire to a power cord it might be best to put some type of breaker/ fuse block in between
Steel pole and I was thinking of designing something like the pole locking mechanisms from this years game, only instead of being one pneumatics, it’s just permanent.
Cause it’d be cooler to use motors to move it up and down the pole.
CIM peak power = 321 W
321W * 4 = 1284 W
Assuming gearbox efficiency of something extremely conservative like .5
1284W*.5 = 642W
25 lbs * 10 ft (tallest most bedroom ceilings would be) = 339 joules
Power = Work /Time
Time = Work / Power
339 Joules / 642 W = .53 seconds
This means that at half of peak power 4 CIMS will lift a TV of 0 height from your floor to your ceiling in .53 seconds. I guess my point is, how did you decide you needed 4 CIMs for this job?
Oh sorry. It’s not 4 CIMs doing all the lifting. I’m going to arrange them diagonally like:
\ /
/ \
around a rubber ball so that I can move it up and down, but also swing it around the pole to differ in direction. So something like this:
Bold Red means it’s powered:
\ /
*/ *
Moves up
\ /

Moves down
\ /
/ **
Moves right
** /

Moves left
250 ft-lb = 339 joules

Oops :ahh:
I used 8 ft, then thought it would be better to use 10 and apparently didn’t go back and fix the math.
Would this work? http://www.harborfreight.com/1500-lb-capacity-120-volt-ac-electric-winch-96127.html
You’d still need a hefty one, and depending on the performance he wants, it could potentially be very annoying.
A 40 Amp breaker doesn’t mean it trips at 40, it can hold currents above that for appreciable amounts of time.
It works, but it’s not really what I’m looking to do.
It does vertical motion, but it doesn’t do the lateral motion around the pole that I’m looking for.
Any motor suggestions, that are just motors, that run off a 120V AC outlet?
Thinking of salvaging some household appliance motors like vacuums, or like someone said an HVAC motor if that would work.
Why don’t you separate vertical motion and lateral motion into two separate systems? You could have your TV mounted on a pivot bracket and adjust the angle with a fairly slow but powerful motor, then move the whole assembly up and down with a cable-elevator and winch?
No suggestions on AC motors. You could, however, get a battery enough to power the motors for a decent period of time (e.g. a FIRST battery, but smaller) and hook it up to a charging circuit, so the battery provides the current needed to run the motors and the charger recharges the battery at a slower rate then it is discharged.
