Loud Motors...need quieter...

[allroy1975]

I'm building a Jukebox and it's going to be awesome...I mean..besides my substandard wood working skills.  It'll play music and sound pretty good. 

I don't know if you've ever seen a Jukebox with CDs spinning at the top of it - they usually have 3 spinning around and just missing each other- but I wanted to have this on my juke. 

I built it, but the motors I used are pretty loud. 

Here's a video of what I'm talking about with the CDs spinning, and you can hear the motors a little bit.  I think a lot of the sound on that video is just background noise from the 2 computers I'm standing next to, but you gotta beleive me...these things are too loud.

looks freagin sweeet!

sorry I cant help you though.

Cool effect. 
What kind of motors are you using?   It doesn't seem like you would need a very powerful motor.  If you take apart and old PC you'll find several motors such as in the CD drive, floppy drive, hard drive, CPU cooler and the fans.  Probably want to use a brushless motor.  Also you could probably use a single motor and set up a belt drive.

[allroy1975]

It's all gear driven.  I've got some beast of a motor (not fast but overly powerful) with a gear on it, driving 2 other gears that have CDs sticking up out of them.

The problem with a CPU fan is that it's either not strong enough or it'll spin at 900 RPM 

so a slow quiet motor.

You can use a floppy motor with the floppy circuit if you can rig up a pulse generator (555 timer circuit). This will run slow and strong, and with the gearing you probably already have, smoothly.

Should be much quieter than a geared DC motor.

[allroy1975]

That's exactly what I have!  A geared motor! 

I really like the Tape deck idea, but I don't really know how I'd set up either the floppy or the tape drive.

any ideas on that....?

Go with the tape player motor, floppy motors are stepper motors and require a driver.
Just run down to the local good will store, they should have something with a tape deck.

I cant help you with your motor problem , but all the jukeboxes in my town have one cd spinning at the top with 2 mirrors placed in that area to give the illusion.

Here you go:

part numbers ACM-105 (30 rpm 120V, $2.50) and ACM-119 (3 rpm 120V, $3.50).

Here you go:

http://www.allelectronics.com

part numbers ACM-105 (30 rpm 120V, $2.50) and ACM-119 (3 rpm 120V, $3.50).  I've used both and they are extremely quiet and cheap .

Also, it might be cool to do CDs and records spinning to show that it also has older music.  If in fact you do have older music on there.

This is what I was looking for from this board..and you delivered!    30 RPM might be a little slower that what I've got now...but for $2.50 I could pick one up and check it out.

it looks a lot easier to mount than what I used too, however my whole thing is built on a 1/8 piece of sheet metal and my motor sticks up through it...you think that little nub would stick through enough to mount a gear on?  Well it says it's .27" so it might...I'm gonna have to pick up 2 of those. 

Thanks a lot!

I'll let you know how it goes, thanks again...put in the order this morning..hopefully I'll have them by the weekend.

okay, I'm power ignorant--- how do I power a 30 RPM TIMING MOTOR, 120 VAC
( HTI # 111-0057. 120 Vac, 3 Watt timing-style motor. 1.95" diameter x 0.81" thick. 12" long wire leads. Mounting ears on two sides. 0.16" square shaft is 0.27" long. UL recognized. )

Thanks!

You'll need to connect it to 120 Vac if I read that correctly...

*I take no responsibility for...anything *

[Druin]

Should be able to just plug the motor into 120 volt AC outlet directly. All the fancy specs on power consumption are just what the motor will use when running.

[allroy1975]

that's like plugging it into the wall, right?

in america?

[Druin]

yeah...If you don't have 120v AC kicking around...then you may need to look into transformers to step.

[allroy1975]

I plugged it straight into the wall and it spins...very quietly 

So I guess I need to just get a longer cable and a plug. 

Allroy

[Nannuu]

Oh yeah, forgot to mention that I use those because they are easy to plug in.

[allroy1975]

yeah, not an issue.  As long as they're spinning.  Just the nub is too short.  I posted a seperate thread about that.
