Stepgen and 4-phase steppers

The BLDC motor I have, has 3 single wires, and a spot (named COM), where all those wires is connected to one place..

Between A1 and A2 there is 4.4 Ohms.
Between A2 and A3 there is 3.5 Ohms
Between A1 and A3 there is 4.4 Ohms
Between A1 A2 A3 and COM there is 4.5 Ohms..

If that helps..

I have access to winding leads

This is the information (somewhat contradictory) I found so far:

1. In this youtube video its clearly seen that BLDC motor is controlled with 1 x L298N:



2. In yet another youtube video (comment section) it says that to run BLDC you need 2 x L298N:



the reason that we cannot drive BLDC with 1 L298N is "The reason for that is the logic inside the chip - both halves of one full H-bridge are linked in opposite phases - it's either 1-0 or 0-1, which will not work for BLDC motor".

In case it is not possible to control BLDC with 1 L298N and linuxcnc, it would be interesting to rewind the motor to 4 phase (or smth that works)..

I have dissasembled the motor into pieces in order to re solder wires from star to delta. I did not rewind anything, just unsoldered all 3 wires from the com and joined each end to appripriate other end... say we have 3 wires with two ends a a, b b and c c. So I connected a to b, b to c, and c to a. This way I believe (does not mean its true) my motor became delta. With that beying said, nothing changed (does not spin). It still vibrates in one position as if would hold the position...

I guess next step would be trying to rewind the motor (edit: I checked, star and delta windings are the same).. It is certainly not the easy way, but at least now I see what knowledge gaps I made in university... damn

That concludes my journey :/ My only question remains, how that dude from youtube managed to control bldc with one L298n when it is not possible.. fake? Or Magic?
