This paper proposes a brushless DC motor driver based on vector control to address the issues of large size,poor control effectiveness,and poor adaptation to high-power motors in the market.Using GD32C103CBT6 as the control core,the real-time current of the three-phase stator is obtained through the lower sampling circuit,the real-time angle of the rotor is obtained through the magnetic encoder,and the brushless motor is driven by the inverter circuit.GD32C103CBT6 has implemented vector control algorithm through software programming internally,which is more cost-effective and portable compared to hardware vector drive chips,The design and development of high-performance and low-cost brushless motor drivers have become possible.This plan can provide reference for relevant motor drive R&D personnel.
