Abstract
A motor control device and a motor control method capable of performing power limitation of a drive circuit more accurately are provided. A motor control device for controlling a motor by supplying a drive signal generated on the basis of a rotation command value by a drive circuit to the motor includes a voltage detection part that detects a voltage of the drive signal as a load voltage, a current detection part that detects a current of the drive signal as a load current, and a power limitation part that detects a load power of the drive circuit on the basis of the load voltage and the load current, and decreases the rotation command value when the load power exceeds a predetermined upper limit value to perform power limitation.
