Would this work? http://www.harborfreight.com/1500-lb...nch-96127.html

Re: CIM motor + Electrical outlet = ?
 

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.

Re: CIM motor + Electrical outlet = ?
 

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.

Re: CIM motor + Electrical outlet = ?
 

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.

Take a look around at www.surpluscenter.com

Or a bench grinder or skill saw or washing machine or sump pump or attic fan.

I did think of that, using the two different systems, and it'd be so much easier to do, but I'd also like to do this method just to see if it's possible. I was also thinking of separating the systems in the same holding mechanism, so that it pivoted about a foot out from the pole, rather than around the pole itself, but I still think around the pole would be cooler to watch.

I'll keep that in mind, because doing 2 separate systems would be so much easier to actually accomplish.

I was thinking of something like that but I wasn't sure if it'd work. It's basically hooking a battery charger to a battery and then taking power from the battery as it charges, right?

Re: CIM motor + Electrical outlet = ?
 

You said you would be using a ball right? What happens when this ball slips? Feel like replacing the tv? Or will you have a safety system just in case?

Re: CIM motor + Electrical outlet = ?
 

I was inspired by this video:
http://dvice.com/archives/2010/04/ball-balancing.php

So maybe something ball shaped but flexible so it can grip to the pole.

What do you recommend as a safety system?

Re: CIM motor + Electrical outlet = ?
 

i want one of these

Re: CIM motor + Electrical outlet = ?
 

I'm not exactly sure... Some sort of friction system that activates after the tv stops moving? I'm not exactly sure... I would be using a completely different system... haha

Re: CIM motor + Electrical outlet = ?
 

Spring loaded rubber grips that lock on the pole? I could probably use a less powerful motor to hold those open and then when the motors stop moving, those could close.

Re: CIM motor + Electrical outlet = ?
 

use He to make the TV neutrally buoyant, then you could use almost any motor to use it. Or, use liquid He and levitate the TV on superconducting magnets.:D

Ryutso,
If you get this system installed in your bedroom, I have GOT to see some pictures :ahh:

Toby,
What you are asking leaves me wondering about safety. This is a point where we have to really point you to a mentor that can discuss this with you and watch over what you do. Household current is not something to fool around with as it can kill and set fires if mishandled.
As you can see from the above answers, four CIMs are an overkill for this project as you don't need to raise the TV that quickly. We typically are raising devices on a TV set at much less than one foot per sec and typically the height of the TV (30-40 inches) in about 15 seconds. Any faster and the support hardware and structure take too much of a beating when you stop. The garage door opener motor in the link that Sanddrag has given above looks like a pretty good start. Remember that the motor is designed to lift a balanced garage door so it is likely producing the required lift for you project. It might even have all the needed end limit switches that you should use in your project.
