FIGURE 3-1: MOTOR CONTROL STARTER KIT SYSTEM DIAGRAM
The application side of the starter kit is centered on the dsPIC33FJ16MC102 DSC,
which requires very little additional hardware to perform its tasks. The Motor Control
Starter Kit is preprogrammed with an application featuring integrated motor control and
mTouch functionality. The motor control application algorithm is based on the
application note AN1160 “Sensorless BLDC Control with Back-EMF Filtering Using a
Majority Function”.
