Abstract: A rotation electric machine controller includes: a torque command value acquisition section that acquires a torque command value for a rotation electric machine; and a setting section that sets a negative limit value limiting a d-axis current command value. The setting section sets the limit value having a larger absolute value in a case where the torque command value is large, in comparison to a case where the torque command value is small.

Abstract: A rotation electric machine controller that is applied to a system including a rotation electric machine and a power converter is provided. The rotation electric machine controller includes: a d-axis command value set portion that sets a negative d-axis current command value; and an operation portion that operates the power converter to control a d-axis current to the d-axis current command value. The d-axis command value set portion increases an absolute value of the d-axis current command value in response to that the q-axis parameter is larger than the target value. The d-axis command value set portion decreases the absolute value of the d-axis current command value in response to that the q-axis parameter is less than the target value.
