So, the z axis nema 17 motor im using has stripped one of the holes during the belt alignment process, and mounts with the other three OK, but I’m wondering if there is a way to get a replacement motor bearing plate, as I feel it’s a bit of a waste to throw out a working motor just because one hole stripped. Does anyone know of a way to buy individual parts of the motors?
Emily, taking a stepper motor apart can totally destroy its usefulness at the worst, and weaken its torque at the least.
Perhaps the hole can be re-tapped for a larger screw if you are concerned about only using the three remaining screws.
@JohnChamplain is correct, If you take apart the motor it will never work the same again without the proper factory equipment to reassemble it.
NEMA 17’s are only about $15 on Amazon (free shipping)
Ah, I guess iI should have figured that, im so used to swapping armatures in brushless multi rotor motors I assumed I could take these apart too
I’ll probably just use it with three mountjng holes or tap it larger until I decide to upgrade to nema 23’s
Thanks for the help
I’d just pop a helicoil in it, myself. Stronger than original, given threads into aluminum.
If you have acces to the backside of the stripped mounting location, could you simply run a longer bolt through the mount and put a nut on the end of the bolt?
