Current Controllers TRIZ Cases
- BLDC Commutation Phase Tuning Using Current Feedback
Current-driven adaptive commutation tuning helps BLDC motors maintain efficiency and consistent control under changing load and speed conditions.
- Back-EMF Zero-Crossing Circuit for Motor Position Offset Calibration
Comparator-based back-EMF zero-crossing detection calibrates BLDC motor position offset, improving sensor alignment and control accuracy.
- Sensorless Reverse Rotation Detection in De-Energized Electric Machines
Remote waveform analysis detects reverse rotation and estimates speed in de-energized electric machines without installed sensors.
