Bussard blade motors.

Here are some small gearhead motors that could spin Paulbo's photoetch Bussard blades for the classic 18" E kit, courtesy All Electronics.

<a href="http://www.allelectronics.com/make-a-st ... 1.html">58 RPM, 12 V, 20mA</a>
<a href="http://www.allelectronics.com/make-a-st ... 1.html">48 RPM, 7.5V, 21mA</a>
<a href="http://www.allelectronics.com/make-a-st ... 1.html">24 RPM, 12 V, 22mA</a>
<a href="http://www.allelectronics.com/make-a-st ... 1.html">70 RPM, 6V, 50mA</a> This one would be a tight fit. Maybe a good thing.

'Spensive? You bet. Coolness factor?... yep.

...and if you're in the UK there's Precision Microdrives with speeds as low as 20 rpm.

Wish I'd known about these when I built my 18" about 4 years ago. Would've saved me a lot of time and effort building gear boxes from scratch !

I've done that before too. It was not pretty.

Thanks a bunch!

You got it Dunsel! Make sure you get 'em centered well, these babies prolly have a lot of torque. I hope they're pretty quiet in there. We'll see.

True and I will also have to see if they fit in since I had to modify my pylon mounting to the nacelle.
Also,I'll have to look into reducing them electronically-all new to me.

Koo Wong Lee did an excellent build using geared motors and custom fan blades on a 22" over at culttvman.

The effect looks almost exact.

In any event,thanks for passing it along!

I'd really like to know how quiet these are. The engines I made make a sound like an electric train which stands to reason as they are HO scale RR motors.

Not only in the UK, they will ship throughout the EU

Cool...Those UK Microdrives @ 20rpm just may be slow enough to drive the Baylon 5 Station kit... Rotate and meshed to a laser cut 2 inch internal ring gear...even slooooower. Worth checking out.

I've got one to drive the scanner on top of my UNCL S.I.D. model, but I'm going to play with a potentiometer to see how slow I can get it to go without fiddling with gears. Of course, something like a radar antenna is virtually no-load, whereas a B5 would present something of a load that could stall the motor.

If you can do laser cut gears - any chance of selling these? I've alwayd planned to motorise my B5.

All right, here's a place that sells 12v, slow RPM motors on the cheap:

http://robokitsworld.com/index.php?main ... 25ml77goa4

But they're in India. I have no idea if they're legit or not. Any way to find out if they are? According to WHOIS, they've only been around since 2008-08-11, so that makes me more than a little skeptical. Oh, and the fact that they use a GMAIL account for their admin and tech support.

Oh, and would this work?

A very inexpensive "stepper" motor. And it looks very small.

MillenniumFalsehood · Post by **MillenniumFalsehood** » Fri Jul 03, 2009 1:10 am

Stepper motors require circuit boards with PICs to make them move. The motors on this thread move via a geared assembly. The advantage of gears over steppers is that the geared motors don't have the staccato motion that stepper motors do when moving slowly. Geared systems or stepper motors will be noisy. I suggest either using these for the up-coming 1:350 Enterprise or building a sound-proof box around them (not hard - just take corrugated cardboard and wrap a couple layers around the motor. The tiny air chambers will muffle the noise considerably and the plastic hull will dampen most of the remainder).

Seems like I posted this before...

If you need small, these are good.

New to this stuff....

So do you buy which ever motor and add the gears to get the speed down to what you want is that the deal here Umi_Ryuzuki?

I've been waiting for someone to do this! I can't wait to see the result!

Hey, I finally actually bought some of these motors. The first two listed are still available as of 11/1/09. Bought 2 of the 58RPM and two of the 48 RPM. The 58's are really tiny, and I think are small enough that some of the sound (pretty minimal anyway) could be muffled by mounting them in styrofoam. Even though it's a 12V motor it runs well on a 9V. The 48's ,sheesh, one of mine was dead on arrival. They are larger and will fit in the 18"er. They are beautiful and very quiet (particularly the dead one). I would just go with the 58 RPM. These 48's would be ideal on the upcoming E, if it weren't a crapshoot as to whether they work or not at $17 a pop.!

Gonna get two more 58RPMs for that future kit. Can't wait.

I don't know if this could help out since these aren't very "torquey", but they work for me! www.solarbotics.com offers a nice range of very compact micro DC motors. I use them often in my custom Transformer action figures. I am currently using one to rotate the barrels on a small gatling mini gun on an Iron Man War Machine figure.

Has anyone ever successfully ordered from these guys? Gizmoszne? I placed an order a few weeks ago the their emails are bounced back to me as undeliverable. Looking for slow geared micro drive motors (6-8 mm dia, 20-25 mm length). They have them, I ordered via PayPal, but never heard from them again...

Thanks

Scott

Thanks for the tip. Ordered two. BTW, they will be on sale until May.
