While cleaning up at work last week,I found some small 6 volt motors I'd saved out of something, a printer I think. Like an HP Deskjet color printer. Anyway, the diameter seemed right, even if the voltage is low, I can put in a voltage limiter resistor and run it in a Trolley or something slow moving. :) So, with the wife making all sorts of racket at 4 AM, I decided to get up for awhile,and hey, while I'm at it, see how well this motor will fit a PT frame.
I have a couple broken units, this frame has a couple gear nubs broken off, so an excellent candidate for me to try cutting the frame up to fit a motor. I think this motor may be too deep to fit inside a shell, but for experimentation purposes, I will use it anyway. I think most of the retro-fit CD motors people are using are flatter.
Regardless, it's a starting point for me to try my hand at a PT retro-fit operation. A broken frame, a cast-off motor, can't hurt anything, really. Wish me luck!

| I would like to learn how to do that. Document it if you can with pictures. I have a number of tyco engines with bad motors and would like to replace them.

| Yeah, I'll second Frank's request. Sounds like a cool project; recycling little motors.

I have tons of those motors from CD or DVD ROM drives. They are commonly used as spindle motors or laser head positioners. They run fine at 15 volts, but are high RPM and tend to be weak at the low end.
Here are some installations.
This C-Liner truck finally got an FK-130, which has much more torque and lower RPM.
The Y6b has a gear reduction set installed, which is essential with these for a reasonable speed range. The Mabuchi pictured isn't the one that made the final cut. I went through a number of them and settled on a Mitsumi with lower RPMs. I also have a vertical motored version of the IHB 0-8-0 that got a spindle motor like the one in the background (main difference is the longer shaft) with a NWSL gear set.
It should power the PT truck fine, but it will be speedy and IIRC won't fit in the 2-8-0 tender without grinding the frame.

What era CD rom drive are you getting these out of? I seem to find that none of the 650 MB CD drives I open up have this type of motor. Of all the CD-ROM drives I've opened up, I have yet to find a can motor in ANY of them that is over 12v, and my company has thrown out lots of obsolete CD drives. < head scratch > I don't get it. is it a particular brand/make of CD ROM drive that has these can motors?

Jerry,
I find them in ROM drives and CD players. Some older ones have AC stepper motors to drive the disk, but most I've salvaged have these, plus the pancake type for the drawer a lot of us have used for PT repowers. I don't know why you haven't come across any, but I think you should skip these 3 pole types and try these 6 pole motors, which are much slower and have buckets of torque:

These are great near drop-in replacements for Rivarossi locos.
