100A UAV ESC — BLDC Motor Controller
High-current electronic speed controller developed for UAV BLDC motors with compact power-stage design, gate-drive circuitry and embedded motor control.
Project Overview
Development of a high-current electronic speed controller for UAV BLDC motors. The project included power-stage architecture, three-phase MOSFET bridge, gate-drive circuitry, current and voltage sensing, MCU control electronics, power supplies and motor interfaces. Particular attention was paid to high-current PCB layout, switching loops, grounding, thermal management, power integrity, MOSFET placement and minimizing parasitic inductance in the power stage. The work covered system architecture, schematic design, component selection, multilayer PCB layout, manufacturing preparation and hardware bring-up.
