Wally,

Actually, the motor CAN go on EITHER end, but you are correct, it
USUALLY goes on the rigid mount end. I have seen designs where the
stepper/motor is USED as the SIMPLE mount! It actually works pretty
well, if the loads are appropriate for the motor. (I see motor
designers cringing out there :-) )

Rigid mounts on both ends are used by machining centers almost
exclusively. But you are right, it takes some good engineering to
make this work. And usually temperature control also.
