I was told that:

You simply cannot use a single L298 to drive a brushless motor.

 

You need 3 H-bridges to in order to control each of the 3 coils. 

 

A L298 has only 2 H-Bridges in it and can only control the 2 of the 3 coils.

 

You would need 3 L298 motor drivers to control all 6 coils which can be done but practically generating those signals yourself would be painful.

 

What is your thoughts?

I guess it would depend on how big the motor was...  (??)

It seems like I saw a good replacement for the L298...  can't remember...  it's there...  Search for it... in dronebot youtube...

 

Good luck...  thank you for keeping us updated on your Solution when & if you find it...

 

 

Have Fun,
