Abstract
A motor control device that enables a reduction of an unpleasant sensation caused by vibration or noise occurring in a motor is obtained. A motor control device including a first control unit that drives a first motor winding and a second control unit that drives a second motor winding is such that the first control unit selects the lower of values of an own power supply voltage and a power supply voltage of the second control unit and outputs a post-selection power supply voltage, and computes a target d-axis current, a target q-axis voltage, and a target d-axis voltage using the post-selection power supply voltage.
