  "textContent": "A main power supply (10) having a large capacity and a backup power supply (20) having a small capacity are switchable by a power supply switching determination unit (25) in a system. A motor control device (300) drives a motor (80) by the main power supply (10) or the backup power supply (20). A drive control unit (40) outputs a drive signal, calculated by feedback control of the current detection value with respect to the current command value, to an inverter circuit (70). When the power supply switching determination unit (25) switches from the main power supply (10) to the backup power supply (20), the drive control unit (40) moves from a normal control using the main power supply to a backup control that restricts an electric power consumption and prevents the backup power supply (20) from stopping.",
