无传感器的BLDC电机控制:The SPMC75F2413A digital motor controller developed by SUNPLUS is well suitable for wide range of variable voltage and variable frequency motor drives. It supports up to two channels of six-independent PWM waveform modulated output and others peripherals that need to be implemented in real product. This application note describes the fundamental theory and control topology of BLDC motor, and the position sensorless detection scheme based on position detection control (PDC) timer module on SPMC75F2413A. Finally, it shows the sensorless is cost and reliability effective in comparison with the hall sensored solution through the experimental results.
