You are considering it from an electrical engineering perspective. Speed vs Torque. It's more a digital motor with a rotor position that can be easily controlled (read head on floppy drives).

It is a brushless motor and it's strongest torque (traction or holding) occurs when the coils are energized. They have fractional hp ratings (>34.3mN●m). To do something in the real world, you typically need some gearing. This one does: 64 5.625° steps.

I extracted the following speed torque curve from Stepper Motors, which is a fairly good resource to understand the theory. with the rearing, I'd expect the holding torque up to 120Hz (120 revolutions/sec).

So you can do something, but not much. I'd check out Brushless DC (BLDC) motors if you want to do something.
