In this video, you will learn how you can design a motor control algorithm for controlling the speed of a brushless DC (BLDC) motor. You’ll learn how different components of the system work, such as the six-step commutation logic or trapezoidal control and the three-phase inverter. We’ll also discuss why we observe ripples in the speed and torque responses of BLDC motors and give you intuition into the concept of inductive flyback.
The model used in this video is available in this GitHub repository: github.com/mat...

This is... this is honestly one of the most enjoyable videos I have ever had the privilege of enjoying. This entire series in incredible.

@alim6786 5 лет назад

great job We hope that a similar series is made about direct torque control of permanent magnet synchronous motor and focus on the latest research in this regard

I have actually never seen such a short precise explaination about Motor Control 👍

@synapticmemoryseepage4447 2 года назад

This is complicated material to learn and review. That these videos are succinct makes it easy to watch a segment as many times as needed.

Excellent video, Melda! At the end of the video you mention PWM will be introduced in the next video. Has the next video been created? If yes, what is the link? Thanks.

@meldaulusoy8389 4 года назад

The video on PWM control has been recently published. Please find it here: That video has been posted recently. Please find it here:

@@meldaulusoy8389 Do we actually need a back emf if we replace a bldc motor I mean does the back emf needs to be implemented if we make the equivalant circuit, i try to test the motorcontrollers current and will measure if the commutation is going the right direction when controlling it, but does back emf have a lot of effect or can i ignore the back emf when realizing the back emf?

@debashischakraborty6914 11 месяцев назад

I have a question here. It's said in this video that to vary the speed we need to vary the DC supply voltage to the inverter. So instead of varying the DC supply if we change the switching speed of commutation in that case also we can achieve a faster or slower speed. Isn't it?

@raefsiam 3 года назад

Nice work Thank you very much

@mahimelesse9142 4 года назад

In the case of electric vehicle the motor acts as a generator, it produces kinetic energy, and I need this energy back to the battery for charging it(Regenerative braking system). I don't understand how to the inverter work when the motor act as a generator?

@davesuess1195 3 года назад

Can we see a similar video for four phase? Wouldn't 4 phase be a better choice for electric vehicles as there would always be power applied to a coil leg. Would this create more power to size in electric vehicles?

@JimmyZeng 2 года назад

Real BLDC motors are delta wired instead of Y wired, so they don't actually have this issue, Y wiring is easier to demonstrate I guess?

@princenoah21 2 года назад

Can anybody answer this one? When I was scrapping, I came across what looked like a brushless motor for an AC fan instead of an induction motor. What's the point of that? Don't the AC fans only need to spin 1 way???

Can I expect the same efficiency in both directions of a Sensorless motor without having to reset or reprogram a basic rc esc? Simply put, can I expect the same efficiency by simply switching 2 of the 3 motor wires? Thanks
