Old Electric Motors and Brushes

       Remove this ad - become a site supporter!
Hello all,

I have found a few old motors and I am wondering if anyone has experience or information with any of these.

The motors that I have found are:

Yokomo Twisters (red label)
Kyosho Stock
Marubeni Stock
Kyosho Lemans (gold case?)

Any information or links to information would be appreciated.

Also, does anyone know how long these motors can be left in storage without them deteriorating? They have been locked up in a case for approximately 10 years.

well, the technology is for sure outdated but i'll bet they run. they won't hold up well to the high voltage of the new cells that most are using so they might not live as long. the biggest thing is that the magnets have probably lost a lot of their strength, if you know someone with a magnet zapper, you just might be able to get them back to near full strength which will make the motors run a fair bit better. i think the kyosho gold motor is a 360 but i don't know what wind it is...as for the others, i'm clueless....

Many Twister motors came with the red foil lables.Is there any markings on the can?The armatures were usually not marked.The Kyosho stock motor is more than likely a 27 turn motor with 12 to 18 degrees of timing.The Lemans in a gold can was a 16 or 18 turn if memory serves.Last but not least is the Marubeni
I have no clue!

Thanks for the information.

My plan may be as simple as removing the brushes, and tossing the motors themselves in the trash. I may keep them in storage for a while longer, but if they are useless to me know, then they may be useless in the future.

Now this leads to the follow up question,

Are the brushes going to be scrap also (they are over 10 years old, and the motors have never been used except for a partial break-in period)??

personally i wouldnt throw them away even if they are 10 years old. maybe if you kept the armatures they could still be useful. or use the motors themselves in a vintage electric car or have some sort of car to just play around with and throw those motors in there.

The brushes in those motors are pretty soft compared to todays motors, they aren't nearly as fast as todays motors either. If the motor is a 480 Gold, it is a 25 turn, quad wind. Not sure what it is if it is a 360 Gold. I believe that most twister motors have a # engraved on the can, near the timing mark, but I can't remember what all the #'s were.
Some people like to collect those motors
