  "textContent": "A motor drive system includes a battery, double-stator axial gap motors, inverter circuits configured to control power running drive and regenerative drive of the double-stator axial gap motors, step-up/step-down circuits configured to adjust at least voltage of regeneratively generated power of the double-stator axial gap motors, and one or more control devices configured to control drive of the inverter circuits and the step-up/step-down circuits. Each of the double-stator axial gap motors includes two stators. Each of the inverter circuits are connected to a respective one of the two stators. The inverter circuits are connected in series. A single step-up/step-down circuit among the step-up/step-down circuit is provided for each of the axial gap motors. The single step-up/step-down circuit provided for each of the axial gap motors is connected to one of two inverter circuits connected to the two stators among the inverter circuits.",
