Reference design
Industrial Motor Driver Board
High CurrentIndustrial
Overview
A reference design for an STM32F4-based industrial motor driver board — a high-current PCB with industrial interfaces. It suits drive and automation applications that demand high reliability and noise immunity.
Design highlights
- STM32F4 MCU (Cortex-M4, FPU) for real-time control and PID/FOC algorithms
- High-current MOSFET/IGBT power stage with heavy-copper layout for thermal performance
- Industrial RS-485/Modbus and CAN bus interfaces for distributed systems
- Over-current, over-temperature, over-voltage and reverse-polarity protection
- Control-signal isolation from the power stage for safety and noise immunity
