Abstract: A motor controller is configured to control a driving of an AC motor. The motor controller includes a voltage calculation part, a voltage limit value generation part, and a d-axis current adjustment part. The voltage calculation part is configured to calculate a voltage instruction value. The voltage limit value generation part is configured to generate a first voltage limit value at which a power conversion efficiency becomes substantially the maximum corresponding to a drive characteristic of the motor. The d-axis current adjustment part is configured to adjust a d-axis current on the basis of a deviation between the first voltage limit value and the voltage instruction value.
