Abstract: Aiming at the demand of high-reliability and independently controllable controller devices for the commutation control of Brushless Direct Current (BLDC) motors, this paper designs a six-step commutation control system for BLDC motors based on a domestic dual-core RISC-V architecture Microcontroller Unit (MCU) (HKSR5102). Centered on the domestic MCU, the system is equipped with a three-phase full-bridge power drive circuit, multi-type rotor position detection circuits and signal sampling circuits. By adopting the six-step trapezoidal wave commutation strategy, it realizes forward/reverse rotation, speed regulation and stable operation control of the motor. Test results show that the system features accurate commutation logic, precise PWM timing and regular phase voltage waveforms. It can operate stably in the full frequency band without distortion, phase loss or phase jump issues.

引言
无刷直流电机凭借高效率、长寿命、低噪声等优势,已成为家电、汽车、航空航天及伺服驱动领域的核心执行部件,其平稳运行依赖精准的电子换相控制,六部换相(方波控制)是应用最广泛的基础控制方式。当前国内电机控制系统多依赖进口MCU与驱动芯片,存在供应链安全与技术受限问题,难以满足高端装备自主创新需求。
本文依托双核RISC-V架构HKSR5102 MCU,构建软硬件全链路国产化的无刷直流电机六部换相控制系统[1]。系统集成电源管理、三相功率驱动、电流电压采样、霍尔、旋变位置检测、通信接口与保护电路,支持 9~36 V宽压供电,可实现有感/无感换相、转速闭环调节及正反转控制。通过优化六部换相逻辑与PWM输出时序,确保电机在60° 电角度区间有序切换导通相序,形成稳定旋转磁场。实验验证表明,系统换相平滑、动态响应快、电压波形规整,高低速带载能力均衡,可在严苛工况下长期稳定运行。
该研究为国产MCU在电机控制领域的规模化应用提供可行方案,实现电机电控核心技术自主创新,对推动航空电子、工业自动化等领域的国产化与技术升级具有重要意义。
