    Keep up the good work
    It was the only one I could find in house...
    Actually I do not even understand the term BLDC... There is no way that kind of motors to work with DC...
    They are simply triphasic motors...

    I am about to recive a larger 'BLDC'...
    I will post progress and new schematic and firmware after...

    The term BLDC or Brushless DC comes from the fact that with a BLDC motor, only two or three stator coils are energised at any given time and represents a DC motor turned inside out, as opposed to the virtually identically wound 3ph motor that energises all three windings, often in 3ph sinusoidal pattern.
