Abstract
Provided is a motor control device capable of suppressing a sudden change in torque due to spike noise. A control device (motor control device) continues motor control using dq-axis current command values Id* and Iq* (current command values) or dq-axis detection current values real_Id and real_Iq before detecting a noise state (detection current values before a current supplied to a motor suddenly changes) instead of dq-axis detection current values real_Id and real_Iq (latest detection current values) when the current changes suddenly.
