Electric vacuum pump for automobile

The invention discloses an electric vacuum pump for an automobile. The pump comprises a motor assembly, a shell, a stator component, a rotor and a pressing cover, wherein the shell is provided with an air inlet and an air outlet; the stator component and an output shaft of the motor assembly form radial off-center; the rotor is in sliding connection with blades which can be driven to rotate in the stator component by the motor assembly; the shell and the pressing cover form a closed buffer cavity, and air enters the closed buffer cavity through the air inlet and is discharged from the air outlet; the stator component comprises a stator seat, a stator and a stator cover in sequence, the stator seat is provided with an air inlet slot communicated with the air inlet of the shell, and the stator cover is provided with an air outlet slot communicated with the closed buffer cavity and the air outlet of the shell; and the axial width of the stator corresponds to the blades. The pump can meetthe vacuum degree needed
