The invention discloses a motor suspension device of a pure electric vehicle and an energy recovery method thereof. The device comprises a suspension support body, and the suspension support body comprises a support, an outer pipe, an inner pipe and a rubber main spring, so that when the pure electric vehicle runs, a variable load is generated through work of a motor of the pure electric vehicle, and the variable load is transmitted based on the suspension bracket body; and an energy recovery system which comprises a piezoelectric energy feedback unit, a voltage adjusting device and an electric energy storage device, variable acting force generated by the variable load obtained through transmission acts on the piezoelectric energy feedback unit, an electric polarization phenomenon is generated, induced current is obtained through adjustment of the voltage adjusting device, and the induced current is stored in the electric energy storage device, thereby supplying power to the pure electric vehicle. Therefore, the problem that the endurance mileage of the pure electric vehicle is limited in the related technology is solved, the recovery efficiency of piezoelectric feedback energy is improved, damage of the pulse voltage to the super capacitor and the storage battery is reduced, and the service life of the super capacitor and the storage battery is prolonged.
