Run 3-Phase AC Motors in Open-Loop Control and Calibrate ADC Offset
Uses open-loop control (also known as scalar control or Volts/Hz control) to run a motor. This technique varies the stator voltage and frequency to control the rotor speed without using any feedback from the motor. You can use this technique to check the integrity of the hardware connections. A constant speed application of open-loop control uses a fixed-frequency motor power supply. An adjustable speed application of open-loop control needs a variable-frequency power supply to control the rotor speed. To ensure a constant stator magnetic flux, keep the supply voltage amplitude proportional to its frequency.
Estimate Induction Motor Parameters Using Recommended Hardware
Determines the parameters of a three-phase AC induction motor (ACIM) using the recommended Texas Instruments® hardware. The example determines these parameters:
Estimate Induction Motor Parameters Using Parameter Estimation Blocks

Field-Oriented Control of Induction Motor Using Speed Sensor
Implements the field-oriented control (FOC) technique to control the speed of a three-phase AC induction motor (ACIM). The FOC algorithm requires rotor speed feedback, which is obtained in this example by using a quadrature encoder sensor. For details about FOC, see Field-Oriented Control (FOC).
Sensorless Field-Oriented Control of Induction Motor
Uses sensorless position estimation to implement the field-oriented control (FOC) technique to control the speed of a three-phase AC induction motor (ACIM). For details about FOC, see Field-Oriented Control (FOC).
