- This animation shows the correct sequence for commutating a three phase brushless DC motor containing four rotor poles and six stator poles.
Three hall-effect sensors are included with 120 degree spatial separation. The hall sensor output waveforms are shown, which drive the commutation process. The three phase voltage waveforms are also shown, including the effects of inductive flyback. The voltage waveforms are synchronised to an inverter diagram showing which transistors are driven for each commutation state.

Priceless animation! 🙂 Thanks!
how does an inverter air conditioning compressor work like this?
please
Is it possible to control 20 brushless drivers with only one variable resistance for speed in all drivers
Also, is it possible to control the movement of all drives from one selector only?
Thanks អរគុណ❤
Bldc motor rpm, pole formula?
Muito boooom
How to see the hall sensor?
what do you mean?
why does a phase sometimes turn off, turn back on and then slowly fade out?
inductive flyback
How do I contact you for inquiries

So that's actually an AC signal, interesting.
that is wrong. just because a signal is periodic does not mean it's AC. in Electrical Engineering an AC signal is defined as any signal that changes its polarity AND is periodic. if you look at the phase voltages they are only in one direction and never go negative. moreover the average value of the signals are positive. a true AC signal's average value , for example a sinusoid , is 0
If you look at one phase, and we have for instance 12 volts of supply voltage input, a sequence of alternating 12v 0v and 0v 12v, wouldn't we have a 12v RMS (+12v -12v) square wave in the output?
another subject I realized:
I see in the video that the sequence on/off of the switches is this:
s1: 110000
s2: 000011
s3: 001100
s4: 000110
s5: 011000
s6: 100001
But wouldn't it be better if it looks like this?
s1: 111000000011
s2: 001111100000
s3: 000000111110
s4: 000011111000
s5: 100000001111
s6: 111110000000
For me the motor performs much better.
