My limited understanding of piezo steppers are that they are better
suited for low torque and high resolution than standard steppers.

They are also useful where a creating a magnetic field may cause
problems, or a huge magnetic field external to the motor may inhibit
correct operation of the motor.

The tiny piezo steppers coming out in the last year just amaze me in
terms of size, speed, and strength, though!

I would be very interested in creating a pico milling machine using
them just to say I did.  Imagine milling snowflakes from tiny chunks
of ice...
