<P>PROBLEM TO BE SOLVED: To improve TN characteristics of an electric motor. <P>SOLUTION: The motor control device comprises: a control part for controlling supply of drive current to an electric motor; and a rotation speed detecting part for detecting a rotation speed of the electric motor. The drive current includes a d-axis current and a q-axis current. The control part calculates a q-axis current instruction value which is a target value of the q-axis current based on the torque instruction value to the electric motor, and calculates a d-axis current instruction value which is a target value of the d-axis current using the difference between the rotation speed of the electric motor and a predetermined base rotation speed of the electric motor and the calculated q-axis current instruction value to perform a vector control to the electric motor using the d-axis current instruction value and the q-axis current instruction value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
