The invention discloses a motor of a deep-well pump and a sealing element thereof, and is characterized in that the motor comprises a first side edge, a connecting edge and a second side edge which are connected in sequence, the first side edge, the connecting edge and the second side edge are connected to form an annular element with an opening, and the section of the annular element is of a U-shaped structure; the first side edge and the second side edge are both elastic bending pieces. The sealing piece is arranged to be the telescopic piece with the opening, when the sealing piece is used, the sealing piece faces the high-pressure cavity, the pressure in the high-pressure cavity is transmitted to the low-pressure cavity through the sealing piece, in other words, deformation of the pressure can be borne through stretching and retracting of the sealing piece, the sealing effect is guaranteed, and the sealing piece adapts to sealing of two cavities with different pressures. 本发明公开了一种深井泵的电机及其密封件，其特征在于，包括：依次连接的
