help determine a stepper motor

[circuitland]

How is every body doing?
I have taken a motor out of a old stereo system the motor has four pins the two of the pins have a positive and a negative, the third one has a letter A written on it and the other on has nothing written on which. We have a school project and we are doing a 3 axis motion controller like a wending maching picking and place machine kind of thing. so i just to use the motor for experimental purposes. Before we actually buy a stepper motor and mess with it.

Q- Is this a stepper motor or not?

Have a great day

If you turn the shaft, does it turn freely, or does it step from position to position?

If the latter, then it's a stepper motor.

hi
welcome to the forums

most likely not, the majority of tape deck, record deck motors are just standard motors and as is common in this situation, they have input/output connections for speed monitoring and control

many tape decks have the ability to be able to vary the speed of the tape and this is how they do it

In searching around, I found a few people also asking for the specs on that motor, but no one having the specs.

I did find this thread where someone is replacing that motor. They are trying to fix a casset player... your tearing one apart. HA!

Anyway, the replacement they found was from Poineer and goes by EXA1241. But I couldn't find anything about EXA1241 either. Just noticed that on this sales page it is called "EXA 1241 TAPE DECK MOTOR PIONEER XDZ-55T = MMI6H2LWK / 12V"
(I did not search at all for xdz-55t, and now I have to head out the door.)

No where at all did I read anyone refering to it as a stepper motor. I agree that it likely is not.


Other things you can destroy to find a stepper motor I have heard people mention is a floppy drive and a inkjet printer.
