PIONEER CT F 1250 - rxm-047 REW MOTOR VOLTAGE QUESTION ?

[McMarantz]

Hello For all
Please help
How much volt is Pioneer ct-f 1250 deck tape : rxm-047 take-up motor?
And this motor is right or left side run?
Thanks
Gurol

Have you checked the service manual that is available on this site?

Pioneer ct-f 1250 take up motor voltage

Hi
I have service manual but dont write the motor voltage

I don't understand why you are asking the question. Polarity doesn't matter, as the motor doesn't have any electronics inside. Is your T/U motor defective?

Specs like RPM at a given voltage are almost never published at a servicer or public level for these sorts of motors- only Pioneer (and Mabuchi, or whoever) knows/knew.

Hello Gurol,
here is a German link with details about the motor.
It is in German but understandable...
Hope it may help you
Have a nice and happy 2010!

So it doesn't matter which way the motor spins? :thmbsp:

Not really. If a motor is controlled externally (as in this case), all one has to do is reverse wires if a replacement spins the wrong way. For example, there's a Technics motor that is a drop-in replacement for the capstan motor on a CT-F1000, but it spins in reverse. It's the IDENTICAL motor, and all one does is reverse the red and black leads on the PCB when you install it.

Stelirem, that's a nice find! Thanks for sharing that.

I was making a joke.

Sorry, dude. Not always possible to tell here who gets it and who doesn't, so I always err on the side of "doesn't."

And you're wise not to, Pacific. Sorry to resurrect this ancient thread, but I have the same issue now with my (long performing reliably) 1000. I see alternatives out there, but I'm not sure if I'm buying a pig in a poke, because the Panny originally discussed isn't available and the Mabuchi RF-510T doesn't appear to be either. I HAVE new old stock (about a half dozen of them) Mabuchis for my 1250's in storage (minus the Pioneer housing) and I have much newer replacements for my 93 (ditto). What I don't have is anything that drops in for the 1000. I have the motor about 3/4's of the way apart, and it's still frozen solid. (The circumstances are spooky, BOTH the 1250 and the 1000's capstan's went South at more or less the same time.) I haven't popped the bonnet on the 1250 yet, but I'm not as concerned, as I know it's the belt (right capstan spins happily along because it's the motor shaft) and I have about a half dozen of belts as well, some of them NOS from Pioneer.) I'd really appreciate any advice, SOMEBODY'S got 'em, because the machines are ankle deep on the bay.....

1250 was no problem, it's fine now, but the 1000 motor issue seems to be a tough one to solve. I've got a couple of motors on the way, I took one of the 1250 motors and it worked fine but was too fast and didn't have sufficient adjustment range on the back of the motor to get it down to 1khz in=1khz out. But it came close. Along with this RT-1020L play switch thing I posted about elsewhere this has been the weirdest two or three weeks in a quarter century of collecting Pioneer vintage. I still have hope for the 1000, but the 1020L's going into storage until a part shows up somewhere.
