What I think you are looking at in the top picture, top right hand side is a brushless DC motor, which would be controlled by output from a computer that would tell it to turn a certain number of revolutions in a specific direction. It is likely that the drive gear never does rotate 180, so rotating the drive gear may work.

The concern would be why the gear wore out. It is obviously being overloaded, which could either be a processing problem in molding the gear or it could be that whatever the actuator is trying to turn is not turning a freely as it is supposed to.

At any rate, it would definitely be worth a try. The only downside I see is expending the time to remove the actuator.
