Understanding Field-Oriented Control | Motor Control, Part 4

Field-oriented control (FOC) is a technique used to control various motor types, including permanent magnet synchronous machines (PMSMs). FOC makes use of Clarke and Park transforms that convert the three-phase sinusoidal currents into the direct and quadrature currents. You’ll learn how the direct and quadrature currents are controlled to bring the stator field vector orthogonal to the rotor field vector to maximize the generated torque.

I watched this video (the others too) when I started working on my first FOC. now I designed and implemented a FOC on a Bldc from scratch.
The results can be seen in my videos.

Thank you, your videos helped me so much!!:)

Very useful series of videos on Brushless motor control. Thank you for your effort in creating and sharing these videos with us.

Melda， Thank you so much for preparing such an engaging video series. Although I have been working in motor control for many years, your illustrated explanations have helped me fill in many details that I had previously overlooked when explaining control principles to others or analyzing and troubleshooting motor control issues. Whether you are a novice just starting to learn about motor control or a seasoned professional, there is something to gain from your presentation. Once again, thank you and I wish you a happy and fulfilling work and personal life!

This is by far one of the best videos with proper description. Keep up the good work!

[korkutterkan]

I am very grateful for you providing this video. Been trying to understand how FOC for BLDC motors work through reading articles which provide only two sentences of explanation followed by the equations. Finally, after watching this video I am beginning to understand the topic. Your explanations and the animations were really good and very helpful. Thank you a lot! :)

[BarbarosS]

Melda, you have truly made me proud. Thanks for a very clear and understandable explanation.

[Busabuck]

Having to watch this multiple times. Each time a little light blinks. Great instructional videos.

[kleindavid]

this explanation is brutally awesome and one of the best things I have ever seen in my life (including movies)

[PlcScada]

This is the best video I have come across on this subject. This is how a teacher has to tackle all the subjects then he goes to the equations. but you are the best

[Globalian]

The visual explanation in this video is magnificent!

[eugeneleroux]

A great presentation with impressive animation. Thank you.

[zeynelkoc]

Dört video da temiz ve anlaşılır anlatımınızla mükemmel olmuş. Ellerinize sağlık...

[canakman]

One of the best helpful video on FOC. Thank you.

[samirbouguerra]

Best explanation and animation I have ever found

[dennischristoph]

ImO simply one of the best videos on the web regarding FOC basic explaination

[TopicsInControlSystems]

Excellent presentation! The graphics are superb and your explanation was great. Nice work!

[CyrilJohnArickathilMRM]

the animation really helps to understand and get the background

[sbmuthuraman]

Thank you so much for the BLDC motor control series.. very useful to start simulation with Matlab Simulink

[Kmreddsadad]

Explanation and representation is great. Thanks

So you are controlling the magnetic field to always be 90 degrees to the affected rotor, and the motor speed and torque by the amplitude of the magnetic force. You do this by sensing the rotor position, the current and voltage going through the coils, and controlling the current of each coil, to keep the magnetic field at 90 degrees.
