Teaching Old Motors New Tricks (Part 1)

Introduction to motor control, discussion of feedback, feedforward, PI controllers, PID controllers, digital control and sampling, and finally, an introduction to Field-Oriented Control.

Teaching Old Motors New Tricks (Part 2)

Overview of Field Oriented Control plus a VisSim lab exercise to synthesize and test a Field Oriented system.

Teaching Old Motors New Tricks (Part 3)

Topics include Space Vector Modulation, Field Weakening, Current Regulator Decoupling, and Field-Oriented Control of AC Induction Machines.

Teaching Old Motors New Tricks (Part 4)

Finish the discussion of Field-Oriented Control of AC Induction Machines, and then we discuss Field-Oriented Control of Interior Permanent Magnet (IPM) motors. Next, we cover observers, and finish the presentation with a discussion of various sensorless Field-Oriented Control techniques.

Teaching Old Motors New Tricks (Part 5)

Presentation of TI’s sensorless motor control solution, “InstaSPIN TM -FOC”.

Field Oriented Control of Permanent Magnet Synchronous Motors (PMSMs)

Step-by- step procedure of how to do Field-Oriented Control (FOC) on a permanent magnet synchronous motor, which includes most BLDC motors. Observer technology is presented, followed by a discussion of some sensorless techniques which allow you to do FOC without a shaft sensor.

Brushless DC Motors and Control – How It Works (Part 1)

This presentation is a very simple introduction to brushless-DC motors and an overview of trapezoidal commutation.

Brushless DC Motors and Control – How It Works (Part 2)

We continue with our discussion of trapezoidal commutation, and briefly touch on the idea of sensorless trapezoidal control.

Introduction to InstaSPIN TM -BLDC Motor Control Solution

This video discusses how to perform sensorless trapezoidal control on a BLDC motor by integrating the back-EMF waveform to create a flux signal. This signal is then compared to a threshold which is independent of speed to create a commutation event.

Permanent Magnet AC Motors – Motor Control and How It Works

This video shows how a three-phase waveform creates a rotating vector on a three-phase motor. By examining the current vector placement with respect to the flux vector, we see how torque is produced in the motor. This is the foundation for Field-Oriented Control, which is discussed at a very high level in this video.
