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.

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?

how does an inverter air conditioning compressor work like this?

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.
