K40 Stepper Motor
Hi
I'm looking to replace a motor on my stock K40 but cant find any information on the motor I have installed, the part number is 42STHM38-1004BDL. I have searched everywhere trying to get any info on this motor but cant find a thing.
Can anyone give me any pointer or advice on a suitable replacement or even an idea of the specs of the K40 stepper motor?
I appreciate the help in advanced.
Dave
Hi David,
You could try Aliexpress https://www.aliexpress.com/item/32785321586.html?spm=a2g0o.store_pc_groupList.8148356.6.788447d5uUACzm
or https://www.aliexpress.com/item/32590189283.html?spm=2114.01010208.8.9.IGCnWy
Cloudray is a good supplier on Aliexpress and they do carry spare k40 parts.
Unfortunately these motors seem harder and harder to get. Maybe supply chain issues?
Another forum that has great tips on getting k40 spares is https://forum.makerforums.info/t/stock-k40-stepper-motor-failed/80262/5
If you can't find these motors, you might want to try replace it with a plain Nema17 motor with 0.9 degree steps. 17 stands for the mounting space (face of the motor). Don Kleinschnitz did some research into the specs and replacement motors see http://donsthings.blogspot.com/2016/06/k40-s-motors.html
Hope this helps and let us know where you landed with the quest.
