Renesas Four-Channel BLDC Motor Controller
A custom Renesas-based four-channel BLDC motor controller integrating three-phase power stages, gate drivers, current sensing, embedded control, and custom PCB hardware.
Overview
This project is a custom four-channel BLDC motor controller built around four independent three-phase power stages. It integrates Renesas gate drivers, power MOSFETs, current sensing, protection, high-current power distribution, and an RA8T1 microcontroller into custom PCB hardware.
Technical
I am developing four independent three-phase inverter stages with current sensing, gate-drive circuitry, protection, and high-current power distribution integrated into a custom PCB. After the electrical hardware, the control architecture supports FOC, SVPWM, closed-loop motor control, and DSHOT and CAN interfaces from a single RA8T1 MCU.
Tools
Power MOSFETs, Renesas gate drivers, current sensing, protection circuitry, schematic capture, PCB layout, RA8T1, oscilloscopes, logic analyzers, FOC, SVPWM, DSHOT, CAN, and embedded C.
