Summary
Application note AN1017 provides a fully working and highly
flexible solution for using the dsPIC® Motor Control DSCs
to control Brushless DC (BLDC) motors with the use of
Hall-effect position sensors and sinusoidal commutation.
The software makes extensive use of dsPIC30F/dsPIC33F/E
peripherals for motor control. The program is written in C
and has been specifically optimized and well annotated for
ease of understanding and program modification.
