Copper loss generated during motor driving is further reduced. In an inverter control device, when driving a motor (7), the control circuit (5) has at least a sine function of the fundamental wave as a q-axis current command value (iq * ). The motor (7) is controlled by superimposing a plurality of odd-order harmonics (sin3ωt, sin5ωt...) Including the third and fifth orders. In addition, the control circuit (5) uses a plurality of odd-order harmonics (sin3ωt, sin) as the d-axis current command value (id * ), as well as the q-axis current command value (iq * ). sin5ωt ...) is superimposed and the motor (7) is controlled.
