To maintain high angle detection accuracy with a simple configuration in a motor control device, including two systems of angle sensors.SOLUTION: The motor control device for driving a three-phase motor 15 includes two systems of angle sensors 11a, 11b. The two systems of angle sensors consist of a first angle sensor and a second angle sensor. The motor control device includes control units 12a, 12b, for outputting an excitation signal to each of the two angle sensors, to which respective induced detection signals are input. A frequency of a first excitation signal of the first angle sensor is different from a frequency of a second excitation signal of the second angle sensor.SELECTED DRAWING: Figure 2
