Vacuum motor

The invention relates to the technical field of vacuum equipment, and discloses a vacuum motor which comprises a shell internally provided with a containing bin. The vacuum spacer bush is located in the containing bin and provided with an inner bin, and the inner bin is matched with the first inner wall of the containing bin to form a vacuum bin; the electromagnetic assembly comprises a magnet exciting coil, a stator and a rotor, the rotor is located in the vacuum bin, the outer wall of the vacuum spacer bush is sleeved with the magnet exciting coil, and the outer wall of the magnet exciting coil is sleeved with the stator; the output shaft penetrates through the first inner wall, and the rotor is arranged on the outer wall of the output shaft in a sleeving mode. The connecting end of the output shaft is fixedly connected with the rotor, and the output end of the output shaft extends out of the containing bin, so that the rotor can be directly connected with an external device of the vacuum motor, the vacuum
