Sorry to be so off-topic, but are there any stepper motor suppliers in
Christchurch? I'm wondering if there are any small enough to fit in a cramped
location, yet powerful enough to change tension on a wire already under
considerable tension? And electrically robust enough to handle regular on-off
switching, while using as minimal an amount of current at as low a voltage as
possible?
This is for my Pedal Steel Guitar The Next Generation ;)
You want to make it self-tuning or something ?
Possibly need some kind of reduction gear instead of making the stepper
do it all.
And it would have to lock still under no-power, else the string would
pull back to slack. Probably need some other controlled clamp to hold
the string once its been tensioned.
