• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...

Here's a simple algorithm that uses conventional microcontroller blocks to control commercially available H-bridges to properly commutate a bipolar stepper motor through a microstepping profile.

Stepper motors find use in many automotive applications,including headlight leveling; adaptiveheadlamps, in which the headlamps turn rightor left with the steering wheel; EGR ...
