Y axis motor on the Hurco KMB fried its commutator.

Motor rebuild service estimated to be too much $$$.

Electro Craft part number is 0703-02-089.

These motors are available on Ebay: https://www.ebay.com/itm/Electro-Cra...oAAOSwhvpdxwcK

Electro Craft part numbers are 0703-02-039 and 0703-02-049. These are probably *very* similar to the 0703-02-089. The question is how *very*?

The good news is the existing motor doesn't have an encoder. The encoder is on the screw for this axis. Don't need to worry about matching the encoder. The Ebay motors have encoders, but they can be removed or simply left unconnected.

Does anybody have a 40 year old secret decoder ring for the Electro Craft part numbers?
