Replacing an encoder on vmc 3020

Does anyone know whether I can use an accu coder to replace the encoder on my vmc 3020?

This is the encoder on the top of the spindle motor. The part number is OE5043 but there are conflicting info online about this part number. Fadal & others (ABB, Radwell, etc.) seems to want to charge close to $1,000. I believe that I may have found the OEM that builds this encoder, but I'm not sure.

Is there a readily available compatible encoder that I can use? Hope you can provide some guidance.

Well, you need to know the specs of your encoder. Type (incremental or absolute), how many channels, voltage, resolution etc. If that’s all the same and you can fit it on your shaft I don’t see why not but maybe some systems have a proprietary type of communication, I think Siemens does that.

Also some encoders drive the U V W of the motor and from what I remember reading about it, it needs timing to the motor somehow.

Not really my forte this sort of stuff but just thought I’d share what popped in my head.

You really need to find some specs, or start reverse engineering things a bit, like how many wires does the encoder have, and can you find any details about the drive that powers the motor?

I'm assuming this is a Fadal, in which case I'd ask over on the practical machinist forum.
It might also be worthwhile having a chat with British Encoders (http://encoder.co.uk), as they might know what you need, or be able to repair or build something that matches.

Post pics of encoder and part number of same + motor + use.
Voltage, resolution, type etc.
See if it has z/, z, aka an index.
If it has an index, the angular positioning of the encoder may be important.

Common quadrature encoders eat 5-24v dc, and interchange.
so a 10.000 count +z quad encoder from one manufacturer will work fine with another makes 10.000 count + z encoder.

The encoder needs to be fast enough for rpm x counts in khz.

Absolute encoders are a different set, and seem to be brand specific.

It is very different if the encoder is for a servo motor, spindle motor, or ballscrew secondary feedback.
