Hello All,

I am still adding to my collection of older motors.
I picked up 5 of these and a hand full of arms a few weeks back.
Everything needs a ton of cleanup, so please excuse how nasty these look.
Arms check out good, motors have ball bearings in both ends and for such
small magnets the motors really cog when turned.
Test ran one of the motors and it was a screamer.
Maybe these are early open motors.
Here are a couple pics.





Thanks in advance.

The photo attachments didn't work Mark. You can also upload the photos to Photbucket for free and then just link to them from here...oops...now I see them (this place is acting weird again on my computer. Anyway, they look to be chopped (?) and others will surely know what they started out life as. The arm in the top one (the G27) looks great from what I can see, and with some TLC, both motors can be spiffied right up.

Thanks John.
Still getting use to the new blog.
I edited the post and it looks like the pics are there.

The top one is either a Koford Feather or A P-S Cube or maybe a Hex. It may even have a Bob Green Cheeta 27 arm in it.

The bottom one looks to be a Camen or a heavily modified P-S.

Here is a brand-new Koford setup for comparison:

I can't remember the name of this Koford set-up, but it was before the above Feather Set-up.

I notice the top motor has what looks like a 10 tooth pinion and the bottom on maybe a 7 tooth. Interesting!!

Yes a 10 tooth for the 27 arm and it's probably a 8 t pinion on the open wind/arm.

Think they called it the U-500

Think they called it the U-500

The U-500 was Koford's first "strap" can motor.

Yup it's a Koford, Thought it was a Proslot when I first looked at it on my netbook. Small screen and bad reading glasses and old age. Oh well. This motor was a much better motor than the early Proslot that had preceded it by some time.

Agreed! The first motor is an early Koford Feather, circa '83?. I never owned one but repaired many that had "Lunched" the magnets. I think the second Camen Cube, circa '81?. The gear ratios, 10:40 for grp27, and 8:42 for opens were common on King tracks.

Below are a couple more from the same era. The first is a Camen - I thinking they called it a "Lightning" It was available in stores, the same time as the Feather. I had opened it up a little more from it's stock form. It was good for older arms, on tracks that benefited from smooth running. The arms were usually .500 dia.

The next one is a Pro Slot "Hex?". This was the latest at the time in '84, just before strap motors began. It used short-stack, .490" dia. arms.




The motor Philipe pictures appears an earlier vintage, but looks like similar technology to the Trinity Infinity and DBX motors, circa '80?

I had one of those Koford box motors like the top one. In a couple of years we dumpted the axle tube for pillow blocks on perimeter frames, went to strap motors with 459 arms and it was amazing to see how much faster the cars got just in the doughnut alone. Those motors were lumps!

[chaparrAL]

Guy , Love the pic of the cut down Camen motor. Back then I ran Alpha kits I put together with magnets from Bill Metros and PS arms. They looked just like that.

Proslot, Koford, rm460.

Thanks all for your inputs.
I'll try to remember and post some after rebuild pics.

The original Koford motor that PDL posted pics of in
post #5 was called the Micro.

Thanks Mike! Year produced? What kind of arm should I stick in it please? This is an NOS setup I got from eBay years ago for 10 bucks.

I don't know what I was thinking..
It just hit me it was actually called the Micro, not the Cube(I edited post # 17 )
The Cube was a samarium cobalt motor marketed,IIRC, by Camen, Proslot & Trinity.

I'm pretty sure the Micro came out in late 1981 - early 1982.
It really became competetive when guys started trimming the cans down
for less gauss.
Those lightened Micro's inspired the Feather, which Paul Pfeiffer
used to win the 1982 & 1983 Nat's.

A Camen/Pooch arm from that era would work.
Just make sure the arm dia. is about .010 smaller than the air gap.
