Hi there, I’ve read your brief carefully and can deliver a compact, reliable 3-phase BLDC driver faster than typical. I’ll design a ≤60 V, 30 A/phase hardware platform with OCP/UVLO/OTP, Hall-based commutation with adjustable timing advance, and a quiet 1–20 kHz PWM range for low audible noise—plus a simple UART/I²C tuning interface and a clean speed loop. I’m experienced with STM32 (G4/F3), dsPIC33, and TI C2000 MCUs, as well as automotive-grade gate drivers (e.g., DRV83xx) and current-sense stages, and I’ve built similar Hall-sensor BLDC controllers end-to-end (schematic, BOM, multilayer PCB, firmware, and test). Components will be chosen from in-stock parts, and I can meet your acceptance criteria (smooth full-range run video + full design package). Message me and I’ll share a concise plan and schedule. Best regards, Samuel Tshibangu

@nathyash

What specific niche are you targeting? Since you mentioned it’s not for industrial or EV applications, are you focusing on robotics? In any case, there are several open-source systems, such as openVESC, SimpleFOC, and ODrive—that are well-suited for brushless motor control. Would you also like me to handle prototype fabrication on my side?
