Those look like the goods. Did you order the motor from the same place in the link ? Any pictures of how you wired it relative to the original robo focus serial pinout ?
I have been running my robo motors at 50% duty cycle to keep the payloads from slipping.

I'll let you in on a secret (of which I'm about to tell the world)... Having a heavy payload (ApogeeU16M with D9 cooling package along with 7 slot filter wheel) on the back of the FSQ, I killed the original robofocus motor. It died a glorious death with slipping, teeth grinding, crunching and a puff of smoke. Truth be told the original robofocus motors are crap. Their gear reduction is around 50:1 so don't have much torque and their step size is relatively large though but still sufficient for nearly all telescope critical focus zones.
Enter the SuperRobo...

These are the same form factor as the original robofocus motor, so no need for another mount bracket, 12vdc, small step size providing improved resolution and a massive 300:1 reduction...enough grunt to scare a troll. FocusMax V-curves are now text book perfect with a heavy payload.
