I've been searching for awhile and can't find an answer so hopefully someone here can help me :)

I just want to know if leaving a servo motor idle, powered but no input, is bad for it? I'm planning on leaving a servo motor powered indefinitely and only sending it a signal to move a bit maybe once a day.

I was trying to setup something with a relay so my microcontroller can control the power to the servo but it's a little bit of a pain, not that it can't be done.

So, should I definitely not leave my servo motor powered for days/weeks? Thanks!

If you expect the servo to hold position, you really should be providing a signal; behavior without might usually be to hold position, but that isn't really guaranteed. \$\endgroup\$ – Chris Stratton Oct 7 '12 at 15:48

This is just like any other motor really, if you're running it inside spec it should be fine. Its lifetime isn't indefinite though. I've done a couple of days with no problems.
