We will try to rewind this 8473, standard winding pattern.

It's looking good Geary.

I always thought that the Strombecker was more than just a "clone" of the Pittmans and Rams, at least as far as the quality goes. If you look at the castings, laminations, plating, etc. they were very good. The arms needed some help, but even the comm doesn't look too bad. I think this is going to be a winner!

[Geary Carrier]

Thanks guys,

Hopefully it will run...

[boxerdog]

I would volunteer to smoke test it. Trust me!

[old & gray]

Thanks guys,

Hopefully it will run...

 

Personal curiosity Geary' where are you going to run this?

Bob,

For the time being in my head, then...?

[Alchemist]

How awesome Geary!

 

I've never seen or heard of this motor before and I'm looking forward to viewing your progress!

 

By the way, if I may inquire, what is the dimension of this motor and how much does it weigh please?

 

Do you rate the size as something comparable to a 36D perhaps?

 

Thank you for sharing.

 

Ernie

[Geary Carrier]

Thanks Ernie,

 

This motor is good for a paper weight...

 

[boxerdog]

My smoke tests could involve any number of A-B comparisons. PM if you are interested...we have a very good dragstrip and several proven cars. 

[Tom Katsanis]

I will vouch for Dave's cars Geary they dominated the first few Rods & Rails events.

[boxerdog]

Thanks, Tom. Might be time to pull 'em out of the dungeon!

David, that comm is actually superior to a Pittman comm, which is a piece of crap.

Greary, that pic answers something I've been wondering for a long time - what effect does having the magnet to the side of the overall magnetic field, do to the the field. Turns out it does exactly what you'd expect it to do. You can see the arm is sucked up against the magnet.

 

I'm as big of fan of padlock motors as anybody. I've got a bunch of them. But they are far from ideal. I'm surprised that they were ever the motor of choice for anything slot car related.

I forgot. As far as I know you're the only person to try rewinding the standard pattern. IMHO sequential was the easy way to go, not the best way to go. Good luck!

 

I'm going to try it someday if I ever get the other projects I have going on out of the way. And that might be a while. My next project is to finally get my home machine shop up and running. At my lethargic pace it might be a couple of more years!

Phil,

This is a KTM 4 volt with the same stack of neos and it runs just fine...

Hi Geary,

 

My guess at being near a 36D size was way off - hahhaa!

 

The 36D motor,  juxtaposed next to the Strombecker motor, makes it look like a "minican" in comparison!   Wow!

 

I could not imagine this being used on a road course - has it ever been?

 

I'd be very interested to see the chassis designed for this motor application, if it was.

 

This motor is good for a paper weight...

 

Then it would be wise not to drop it on your foot - hahahaa!

 

Pardon me for inquiring again, but would you know how many "pounds" this motor weighs please?  LOL

 

What type of RPM range can you expect after rewinding please? 

 

Would you expect a substantial increase in RPM?

 

Thank you Geary.

 

 

 

Hi Phil!

I'm as big of fan of padlock motors as anybody.

 

"Padlock" - That is such an appropriate name for this type of motor!  LOL

 

Thank you.

Ernie, find yourself a comprehensive article on 1960s slot car motors, you will find it fascinating. Most of the early one were re-purposed, to use a current term, from HO trains or any DC powered anything. It was  a great time, Pittmans, Bonners, Rams, Lindsays, and a host of imported motors. There may be some good threads here as well.

Geary, I was commenting on the magnet arrangement of padlock motors in general, not yours. I'm sure the asymmetrical design  was fine for trains. I can't imagine it's worth a crap when performance is the goal. That's just an observation though. Not a criticism.  We all love 'em in spite of all their shortcomings. In fact that's probably why we do like them.

 

How does all that extra Gauss make your KTM run compared to a stock one?

Ernie, that's what the vintage slot car drag crowd calls these type of motors. The first time I read it I had no idea what they were talking about. But I eventually figured it out and as you said it's a perfect name for them.

 

Pittman, Ram, Kemtron, KTM, Strombecker and maybe others made motors like this.

[Alchemist]

Hi Phil,

 

Thanks for the info.

 

For me, it's always exciting to learn more about this hobby of ours!

 

Thank you.

If the can motors were so much better, racers would have been using them instead of the big moose's. Once better magnets came along, and

rewinders were learning the best winds to use, that all changed. One thing about racing, the best stuff always becomes the norm.  

 

Incedently, we started calling them padlocks because, with their laminated construction, they resembled the Master padlocks popular back then.

Ernie, 

 

I did an article on open-frame motors many years ago for Slotcar Bulletin - if you're interested, I can try to dig it out and send you a scan.

[Phil Smith]

Wow, Don. You don't like the rest of us? I and I'm sure everyone else would like to see that. Post it please!

[don.siegel]

Didn't think anybody else would be interested! 

 

Just found the issues, from about 2002 - will post as soon as the hamsters power up my scanner!
