QPT Unveils 1MHz GaN Motor Drive with Sensorless Dynamic Cogging Correction - TimesTech

QPT has unveiled its first 1MHz gallium nitride (GaN) motor drive, featuring sensorless dynamic cogging correction, marking a significant leap in motor control technology. Based on the MicroDyno test ... Read original →

QPT’s 1MHz GaN motor drive triggers a cascade across the industrial control stack: upstream GaN wafer suppliers like Navitas and Innoscience will see higher fab utilization, while cobot OEMs can slash sensor-related BOM costs by over 30%. Compliance-wise, eliminating rare-earth-dependent servo architectures reduces exposure to U.S.-China tech decoupling risks. Competitors like Yaskawa and Inovance will likely fast-track in-house sensorless FOC development or acquire edge-AI startups to close diagnostic gaps. Within 18 months, the fusion of digital twins and edge AI will redefine drives from mere actuators to intelligent nodes—where value shifts from peak torque to predictive maintenance and real-time self-calibration capabilities.
