section to output said current command value sensitive gain based on an output of said current control delay model; anda multiplying section to multiply said current command value sensitive gain by said sign.11. The vector-control type motor control unit according to any one of Claims 6 to 10,wherein said axes current factor phase-correction calculating section comprises:a dq-axes current ratio calculating section to calculate a current ratio of said dq-axes current command values; anda variation angle calculating section to calculate a variation angle based on said current ratio,wherein said motor rotational angle is phase-corrected by using said variation angle.12. An electric power steering apparatus that is equipped with the vector-control type motor control unit according to any one of Claims 1 to 11, and applies an assist torque to a steering system of a vehicle.[Problem]An object of the present invention is to provide a vector-control type motor control unit that compensates a dead time of an inverter without a tuning operation, improves a distortion of a current waveform and a responsibility of current control, and suppresses a sound, a vibration and a torque ripple.[Means for solving the problem]The present invention is the vector-control type motor control unit that calculates dq-axes control assist command values, calculates dq-axes current command values from the dq-axes control assist command values, converts the dq-axes current command values into 3-phase duty command values, and drives and controls a 3-phase brushless motor by an inverter of a PWM control, wherein a dead time compensation of the inverter is performed by calculating 3-phase dead time reference compensation values based on a motor rotational angle which is phase-corrected by using the dq-axes current command values, calculating dead time compensation values by processing the 3-phase dead time reference compensation values by a gain and a sign, and adding the dead time compensation values to dq-axes voltage command values or 3-phase voltage command values.
