it is magnetically detented in the last position. A wide range of step angles are available -- 1.8 to 80°, for
example -- without logic manipulation.
Stepper motors have inherent low velocity without gear reduction. A typical
stepper motor driven at 500 pps turns at 150 rpm. The
stepper motor's rotor inertia is usually low. Multiple
stepper motors driven from the same source maintain perfect synchronization. But the
stepper motor's efficiency is low; much of the input energy must be dissipated as heat...
