The invention provides a motor drive system which is formed by connecting a plurality of double-stator axial gap motors in series, and can suppress the reduction of regeneration efficiency when a regenerative power generation voltage is adjusted and charged into a battery. The motor drive system includes: a battery; a double-stator type axial gap motor; an inverter circuit that controls power operation driving and regenerative driving of the axial gap motor; a step-up/step-down circuit that adjusts at least the voltage of the regenerative generated power of the axial gap motor; and a control device for controlling the driving of the inverter circuits and the buck-boost circuits, the system including a plurality of axial gap motors, the inverter circuits including a plurality of inverter circuits respectively connected to two stators of each of the axial gap motors, the plurality of inverter circuits being connected in series, one buck-boost circuit being provided for each of the axial gap motors, and the buck-boost circuits being provided for each of the axial gap motors. A buck-boost circuit provided in each axial gap motor is connected to any one of the inverter circuits connected to the two stators.
