Summary
Microchip provides a proven, fully functional and
highly flexible solution for using the dsPIC30F/33F to
control Brushless DC (BLDC) motors without Hall-effect
position sensors. The software makes extensive use of
dsPIC30F/33F peripherals for motor control. The algorithm
implemented for sensorless control is particularly suitable
for use on fans and pumps. The program is written in C and
has been specifically optimized and well-annotated for ease
of understanding and program modification/configuration.
