| 摘要 | A motor control device has: a motor current detecting portion for detecting, based on a current flowing between an inverter that drives a three-phase motor and a direct-current power supply, a motor current flowing through the motor; a specified voltage value producing portion for producing, based on the motor current, a specified voltage value as a target value for a voltage to be applied to the motor, and outputting the specified voltage value thus produced; a specified voltage value holding portion for holding an earlier specified voltage value outputted from the specified voltage value producing portion; and a specific period setting portion for setting a specific period based on a voltage difference between two of U-phase, V-phase, and W-phase voltages of the motor. Outside the specific period, the motor is controlled via the inverter based on the specified voltage value outputted from the specified voltage value producing portion, and, within the specific period, the motor is controlled via the inverter based on the specified voltage value held by the specified voltage value holding portion. | ||||||
