Dynamic Equations Algorithm of the Sensorless BLDC Motor Drive Control With Back-EMF Filtering Based on dsPIC30F2010
This application note describes a sensorless Brushless Direct Current (BLDC)motor control algorithm that is imple-mented using dsPIC30F2010 Digital Signal Controller (DSC).The algorithm works utilizing a majority function for digitally filtering the Back-Electromotive Force (BEMF).Each phase of the motor is filtered to determine when to commutate the motor drive voltages.This control technique excludes the need for discrete,low-pass filtering hardware and off-chip comparators.It should be pointed out that all the discussions here,and the application software,assume a 3-phase motor has to be used.
