ABSTRACT:
A first comparison circuit compares the energization on angle outputted from a computer with the energization off angle outputted therefrom so as to output a first binary signal representing whether the latter is greater than the former. A second comparison circuit compares the energization on angle outputted from the computer with the rotation angle of the rotor outputted from the angle sensor so as to output a second binary signal representing whether the latter is greater than the former. A third comparison circuit compares the energization off angle outputted from the computer with the rotation angle of the rotor outputted from the angle sensor so as to output a third binary signal representing whether the latter is smaller than the former. A binary signal process circuit processes the first, second and third binary signals outputted from the first, second and third comparison means so as to output a fourth binary signal representing energization on and off.
