Sensorless closed-loop control of hybrid stepper motors with current regulation

Current control of hybrid stepper motors in a sensorless closed-loop configuration is examined. Rotor position detection is done by monitoring phase current decay times as a result of using a chopper drive. It is shown that with a variable crrent reference chopper drive, three main performance chara...
