ABSTRACT:
A driving control device of a motor includes a phase current control device for controlling a phase current which is fed to a phase coil of each phases of a motor in a predetermined control period of each phase coils so as to become a predetermined target current, respectively, a convergent control device for converging the phase current after the end of the control period of each phase coils and a driving signal generating device for generating a driving signal which controls the end timing of the phase current convergent control by the convergent control device so that the phase current convergent control is ended between a timing at which a reverse torque is generated by the phase current and the end timing of the control period for next phase coil.
