Summary
This application solution demonstrates how to use the
dsPIC30F/33F to control an AC Induction Motor (ACIM). The
solution presented requires a basic understanding of ACIM
characteristics and is based on the dsPICDEM™ MCHV
Development Board. The program is written in assembly
code and has been specifically optimized and well annotated
for ease of understanding and program modification.
It provides basic variable speed control of an ACIM in
open-loop Volts/Hertz mode.

Summary
This application note provides a fully working and highly
flexible solution for using the dsPIC30F2010, dsPIC30F3010
or dsPIC30F4012 to control BLDC sensorless motors
without mechanical position sensors. The software makes
extensive use of dsPIC30F 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 programming.
