The invention relates to the technical field of electric automobiles, and discloses a motor suspension device and an automobile. The device comprises a suspension support mechanism and an energy recovery mechanism; the suspension support mechanism comprises a support assembly, a first vibration reduction assembly and a second vibration reduction assembly. The energy recovery mechanism comprises a piezoelectric assembly and an adjusting assembly, and the piezoelectric assembly is connected with one of the support assembly, the first vibration reduction assembly and the second vibration reduction assembly and is configured to generate current based on the received variable load; the adjusting assembly is connected with the piezoelectric assembly and receives the current; wherein at least one of the first vibration reduction assembly and the second vibration reduction assembly is an active vibration reduction assembly, and the active vibration reduction assembly is connected with the adjusting assembly and is configured to adjust the rigidity of the active vibration reduction assembly based on the current output by the adjusting assembly. According to the motor suspension device and the automobile, the working vibration and noise of the power motor can be reduced, the riding comfort is improved, and meanwhile the influence on the endurance mileage of the pure electric automobile is avoided.
