    Do you have a present means of detecting each phase angle in order to fire each SCR? If so how?

    3ph SCR control of DC brushed motors has gone out of style now with the advent of PWM control, it might be worth looking in to this method?
    Picmicro's have inbuilt PWM modules for this purpose.
