  • The shaft has a 1mm pitch. It’s also stainless steel. That’s because it runs through the center of the rotor magnets; if the shaft were made of a magnetic steel, it would become magnetized over time and that’s usually a bad thing.

    In searching for shaft material, I found no source of M5 X 1 stainless threaded rod, though I did find an alleged source of plain steel rod who didn’t respond to my inquiries. You can have stainless rod threaded by a machine shop, but it’s horrendously expensive.

    It would be very useful for SparkFun to contact the motor vendor about the price to order custom lengths, perhaps a meter, then let us know how to order shafts from them.

    My motor is tired of being a paperweight.

No public wish lists :(
