ATARI 1050 spare parts

Recommended Posts

Hello Community,

 

Through this channel, someone will know where I can get the replacement for this engine below:

 

LC-177E COPAL

 

I leave photography for reference.

The only site that has that replacement, my PayPal account does not accept me to buy it.

 

Link: http://nnelectronic.com/product.php?ProductID=213992

 

Stay tuned.

It's highly likely someone here has a dead mech from a 1050 that this part could be stripped from... In the mean time, I did spot a few around:

 

Quick finds on ebay are pricey:

COPAL LC-177J - https://www.ebay.com/itm/202993025681 ($15+35 USD)

COPAL LC-177P - https://www.ebay.com/itm/350618532123 ($30+15 USD)

 

This one seems to be a good bet:

LC-177 Stepper Motor 12V DC 5400rpm - https://hcess.ca/product/lc-177-stepper-motor-12v-dc-5400rpm/ - $9.99 canadian

 

I wonder what the last letter designates...

Thanks for answering me.

 

The only thing I know about the replacement LC-177E is that it works with 9V. Now, I do not know if there will be an adapter for those spare parts that you point out, since those work with 12V.

The motor is definitely 12VDC. You may be confusing the power requirement because of the 9VAC power supply. The drive circuitry derives 5VDC and 12VDC internally from that.

 

The motor will technically operate with higher/lower voltages than 12V, but the speed will vary. The drive uses the tachometer output to adjust the voltage/RPM dynamically.

Sure is, look at this part of the 1050 circuit

¿Dónde están ubicados?

Tengo esto tomado de una unidad Atari 1050.

The motor is located where it spins the disk (5400 RPM).

 

What make and model is that motor that you show in the photo?

If I buy what @Nezgar tells me, can it be adapted?

That Motor Spindle in the diagram is also +12V DC power, switched through the Q6 transistor

@calaluisrodrigo sorry, my bad, got the wrong motor in my reply :)

 

Do not worry. The important thing is to help the cause.

 

What did leave me very discouraged was the email I received from the manufacturer.

 

Look:

Therefore, I have been looking for a substitute product.

 

Do you know any?

Sorry for hijacking. Does anyone in Europe happens to have spare spindle clamp? That is that plastic flower like shaped part that presses floppy disk centre. I need one.
