The invention relates to a vacuum braking pump of an electric automobile. The vacuum braking pump comprises a pump body (1) and a motor shell (10), wherein a pump stator (8) is mounted in a cavity of the pump body (1), and a pump rotor (7) is mounted in the center of the pump stator (8); a motor stator (9) is mounted in a cavity of the motor shell (10), a motor rotor (11) is mounted in the center of the motor stator (9), and pump blades (6) are mounted on the pump rotor (7). The vacuum braking pump is characterized in that four blade slots (6-1) are uniformly formed in each pump blade (6) and are perpendicular to a vertical center line (6-2) and a horizontal center line (6-3) respectively. The vacuum braking pump is good in vacuum performance and high in strength, is not prone to breakage and has low noise during operating.
