Re: wave drive

1) Wave driving is not used by any commercial I'm aware of. It only
exists as an academic curiosity in the sense it is a way of turning a
step motor.

Wave drives excite only one motor winding at a time. It may turn a
motor but it is utterly inefficient; you get all the vibration of
full-step operation with only 1/2 the torque (remember, only one
winding "on" at a time).

2) Half-stepping: A little less vibration, a little bit more torque
than a wave drive, a little less torque and vibration than full
stepping.

3) Microstepping: About the same low-speed torque as half-stepping
but no vibration at all with a good motor and an accurate (low
distortion) drive.

Most of the above has anything to do with getting torque at high
speed from a motor. The only thing that will do that is a high power
supply voltage.
