Hello,
I am working on a simple project. It is two stepper motors spinning two devices that have physical stop limits. If you overspeed, the devices will be damaged. One of the devices is a vacuum variable capacitor, which has no real "stops" per se, but if you spin it too far in one direction, you will damage that part. There is no way to mount any kind of limit switches, and there is no room to "rig" a screw block to mount the limit switches. I have come to the conclusion that a NEMA 17 or 23 stepper motor ( https://www.oyostepper.com/category-7-b0-Nema-23-Stepper-Motor.html ) with an encoder would be the simplest and safest solution. I have searched around and have not seen much.
Can someone provide a source and part number for such a stepper motor? I am not an expert on this and thought someone here might have a suggestion.
