Tamiya motor experts needed...

[SofaKing]

Can anyone help me identify which Tamiya motor this is? It has a similar can and assembly to the Technipower/Technigold motors but with a different style endbell.

Any help will be greatly appreciated.

Looks like a Dyna Tech

Thanks, that looks like it could be it.

Is this one yours, do you know the specs or what era it would be from?

Never mind by the time I posted this response Tamiyadan gave me all the info I asked for.

Actually what you have was not originally a motor sold by Tamiya you have a MABUCHI RX-540VS there.

MABUCHI made the motors for Tamiya and Tamiya branded them the Dynatech 01R.

the Tamiya version is ever so slightly different with the finish on the endbell, it is more polished.

all the parts interchange between the MABUCHI RX-540VS and the Dynatech 01R.

in Europe and Japan lots of people bought the MABUCHI RX-540VS motor because the Dynatech was rarer and harder to get.

Tamiya would throw a fit if you brought a MABUCHI RX-540VS to a Tamiya TCS race, the motor had to officially be a tamiya version with the proper label.

it didn't mean anything, outside of a tamiya TCS race. You could of swapped the armature between the two and as long as the can had the tamiya sticker you were ok, there were 2 armatures available that I remember a 19 turn single and a 17 turn single. Tamiya gave you the 19 turn with the 01R and offered the 17 turn as a hopup part.

the Dynatech 02H had a 13 turn double and 10 turn double armature option

So officially you can't say it is a Dynatech 01R even though all the parts are exactly the same except for the Finish on the endbell and the tamiya decal.
some people have said tamiya used brushes with more copper then the MABUCHI RX-540VS but i think they were the same for the replacement brushes Tamiya sold.

Wow sir, that is way more than I expected Thank you for all the detailed information, I guess it's still a pretty cool little motor.

Based on all this I'm sure you must know the years these would have been available?

Thanks,
Dave

I came across one of these Mabuchi RX-540VS motors too. Not something I've ever seen before.
