Sometimes those small AC motors can be made to rotate in opposite direction - there is a small plastic cog that needs to be plasced in alternative position.
You need to open it and see what's inside...
And, of course, it is possible to just mount the motor axle other way around, but this depends on what kind of mtor you have.
And of course, this means the motor needs to be dismantled.
Could you post a picture of that's inside your mount? Is it
this?
BTW, ~40 years ago I removed one of the motors like
this one for a friend..
(electrically, motors were in series, working together.. probably to be easily configurable for 110V or 220VAC 60Hz) and I added 60Hz sinousoidal generator for another motor (which I rewounded so it was running at 3VAC).
One motor was perfectly sufficient for tracking.
