Do any of you experienced peoples recognize this Motor Design ???

[5Scheids]

This is inside a Soundesign 3472.

I am somewhat familiar with the Copal Mechanisms and Motors, but what is with this motor Design ???

Any information on the History of this design? Reliability, Commonality, etc. ?

Thank you for ANY and ALL Input.....

Yes I do actually!

Believe it or not, it is a quite common type of motor in clock world. They were originally made by Telechron, but I have also seens them from Toshiba (I believe the Toshiba ones are mostly 220v/50hz as opposed to Telechron).

Used in a lot of different type of flipclocks, Junghans, Bosch, Sankyo, etcetera

Have not seen one in a 'Soundesign'...

Very useful information. Thank you !!!

These are HORRIBLE motors. The Panasonic RC-1280 has one as does the RC-6530. When they start making noise, that's that end of that.
It would seem they're an efficient way to accomplish things because the device that creates the electromagnetic field that turns the little wheel (inside the aluminum can) also acts as the vibrator for the arm that makes the alarm sound, but there's a reason they switched over to the better copal mechanics.

I'm doing a video all this right now (that is, in addition to the one about the Attack of the Killer Tomatoes Flip Clock the Panasonic RC-1280). This is the next video slated to come out. So, I'm glad you're mentioning it. I didn't know about the model you mentioned. Thanks also to flipoclock for the details.

I've actually torn open the motor and have movies of the sound and how it works.

Thank you... I am Very Much looking forward to the next Video !!!

They can be reconditioned, parts replaced, lubricated, etcetera. It is a very specialistic job and I think, if I recall correctly, you are looking at around $90 for one motor.... They would last you another 40/50 years though, so effectively, it would be money well spent :-)

Thanks to your input I DO know that this is a Telechron Motor, but I don't know much else about it.

It obviously has 60 stamped on the outer housing, but other than that who knows ??

So I managed to (very carefully) disassemble this Telechron Motor. It was totally gummed up and the black plastic gear
on the center shaft was broken and crumbling.

I am guessing that it will be a chore to find a source for the individual parts?

Any ideas from you experienced fellows?

I LOVE to fix things, but I don't love to give money to others to fix things when I enjoy fixing them myself, and servicing items for others as well.

Obviously this HAS to be a passion of mine or I wouldn't be spending SO much free time on it.....

I just hate to see items thrown into landfills; especially when they are an irreplaceable piece of history.

Thank you for any and all input !!!

I have learned that this is NOT a Telechron Motor, but a VERY similar motor, most likely a Sanyo.....

[5Scheids]

So I have already heard back from Dave at Telechronclock.com and this is some useful info. for future reference.


"Hi Dale,
Sorry, I can't help with that motor since it's not Telechron. It looks similar, but I believe it was made by Sanyo. I don't know of any source other then to find a junker clock/radio that has that type of motor. I'm not even sure which manufacturer used that type of motor. I doubt it was Sony but could be Panasonic.

It might be possible to use a Telechron S or H-3 motor assuming it runs at 3.6 RPM but the mounting would likely not match.

Good luck,

Dave"

I don't mean to hijack your Forum or anything, but I thought that in the Future this info. may be of use to someone else.

Thanks guys, Dale

How much of the original parts are left? Are there other parts within the assembly that are the same that are in passable shape?

Depending on how much money, or rather time you want to invest, it may be possible to create new components by creating a mold from the parts and then casting new ones. Failing that, and granted you have enough to go from, you may be able to have something 3D printed. I've had a couple old vending machines that had defunct manufacturers and no used parts market to speak of, and I was able to get parts made. This was back in 2016, I'll see if I can find the company that did the work for me- I can't imagine the process has gotten any harder or more expensive the way technology goes.

Where there is a will, there is a way.

[5Scheids]

I was thinking along those same lines myself...

Fortunately the one Plastic Gear failed completely and it seems to have saved everything else from extensive damage.

Unfortunately the part that failed literally crumbled so that I can't get ANY measurements from it.

I work with some pretty good Mechanical Engineers so once I lay out the whole problem
on paper and show one of them the math they will gladly verify the numbers for me before I source
a gear for this little guy.

The last thing I want to do is get it all back together and it doesn't keep time correctly......

Thank you so much for your input.

Here's the video of me tearing into the motor. Posted April 1, 2019.

[LuvBadTV]

First off, I love this site, so much helpful advice - I hope this is way of giving back. I know that the motors in a Panasonic RC 1280 (and similar) are dissed here (and rightfully so), but I did find a way to fix them so they can be used again. Here is the short version:

1. Note the orientation of the motor when it is in the clock right-side up - mark the top side with a Sharpie.
2. Remove the motor completely from the clock.
3. Drill a hole (carefully!) in the spot where it was marked. Be careful not to drill too deep - you don't want to hit a gear - just penetrate the metal can and stop. The diameter of the hole should be big enough to insert the little red straw that comes with spray can lubricants (about .085 inch).
4. Fill most of the motor's metal can with a viscous lube that won't degrade the plastic parts. I used 3M White Grease (Lithium Lube) in a 16oz spray can.
5. Seal the hole you created with either plastic tape, plastic plug or screw.
6. Re-install motor.

I found this repair eliminates the noise/hum/grinding. I am quite satisfied with it - one of mine is going on 3 years - it keeps perfect time. I did have to re-fill another one I refurbed after two years, but I think that is because I didn't fill the metal can.

Instead of drilling a hole I prefer to open up the motor. There is often a lot of old grease in there that you better replace. I made this post about it: https://www.flipclockfans.com/forum/...n-motor-repair
Key trick is the tapping on the rim of the case to get the mechanism out.

I have repaired a few of these this way. With the last ones I did not bother about resealing them anymore. The fit is tight enough that nothing leaks and it makes it easier to open it up again in case issues return.
