In this exclusive Design Guide, the editors of Design World detail other application variations and the vast array of stepper-motor designs.
Stepper motors are in myriad motion-control applications — especially on machine axes that need positioning. That’s because stepper motors accurately control moves to within fractions of degrees without feedback. In fact, stepper motors in traditional arrangements run open-loop without the need for tuning as in servo setups — but stepper motors are making inroads even in designs with feedback. Stepper motors are increasingly affordable as well. That means that designers are now applying them in ultra-simple applications that were once strictly mechanical.
