Help me find small closed loop stepper motor with gearbox?

Hi,

I’m looking for something pretty unique. A closed-loop stepper motor, so a stepper that has a hall-effect sensor, or optical encoder, that can correct for missed/skipped steps, that also has a gearbox, or some other way to maintain torque when powered off.

Also, the smaller the better, ideally around this size https://components101.com/motors/28byj-48-stepper-motor

Can anyone recommend something?

Thanks!
