Summary
Where efficiency and low cost control of the induction
motor drive is a concern, the sensorless Field Oriented
Control (FOC), also known as vector control provides the
best solution. This application note provides a solution for
sensorless Field Oriented Control (FOC) of induction motors
using a dsPIC33F/E DSC.

Sensorless Field Oriented Control (FOC) of an
AC Induction Motor (ACIM) Using Field Weakening
Application Note: AN1206 • Ready-to-Use Solution
FOC control of AC induction motor provides an improved
transient response
Sensorless FOC reduces cost of hardware and increases
reliability
FOC algorithm maintains a tighter control on performance
of motor and hence preferred over simple V/F control
Use of PLL estimator enables very low speed of operation
of motor
Improves efficiency of the system and reduces
disturbances on the supply line
