using servo motors

[jcrews63]

I'm hoping some people in here can help me. I am a furniture builder/artist that has designed a few pieces of furniture that I want drawers to open/lids to close/screens to pop up and various other things that have some weight involved with them. Are servo motors the way to go and can anyone give me a heads up on even where to begin my research on this. I have asked a few shops that sell motors to start but had no luck. Most people just look at me like I'm a little nuts but its doing essentially the same thing as what a cnc machine would use the motor for so I thought I would have a better response here....thanks

if you just want to have the moving parts to go from one stop to another, a dc brushed motor is the way to go. You just need a dc power supply and two limit switches driving a couple of relays.

Although not a fan of steppers, depending on the speed and the mechanism you are using, you may be able to use ordinary stepper motors in the synchronous mode of operation off of AC direct, no power supply or drivers, Transformer & AC rated capacitor only, unless you go with 120v types, then you don't need a transformer, the down side this will be one speed and fixed, but immediate stop start.
Or following the suggestion By Unterhaus, a way with a DC motor would be Scrap Auto Wiper motors mechanism and drive, very powerfull linear drive.

How about these guys. http://www.inca-tvlifts.com/

Downside is that they are expensive.

Al, you could always gear the AC steppers to give the speed you want, right?

That true, but unfortunatly with 1.8° steppers you only get 72 rpm on 60hz, so there is not much room to play with. Depends how their used I guess.
