Abstract: The present disclosure relates to the technical field of electric toothbrushes, and in particular to an electric toothbrush motor. The electric toothbrush motor comprises a mounting shell, an end cover, conductors, a rotor assembly and a stator assembly, wherein the rotor assembly and the stator assembly are fixedly arranged in an accommodating cavity of the mounting shell through the end cover. The first magnetic steel sheets are added to the rotor assembly, the second magnetic steel sheets are added to the stator assembly, each first magnetic steel sheet is placed at the middle part of an interval between the two second magnetic steel sheets, and by the above manner, the relative positions of the rotor assembly and the stator assembly are fixed, so that the response speed is increased, the vibration frequency is high, and the service life is prolonged.
