Abstract: As an intelligent inspection device for overhead transmission lines that can replace manual long-distance inspection, it can significantly improve inspection efficiency and reduce labor intensity. A permanent magnet servo motor with high power density and low torque pulsation was designed to ensure the high precision and stable operation of the intelligent inspection device on the line. The electromagnetic analysis of the motor was carried out through theoretical
analysis and finite element method, and the thickness of the permanent magnet and the polar arc coefficient were optimized to reduce the torque pulsation of the motor. Finite element simulation software was used to check the vibration of the motor, calculate the radial electromagnetic force, and check the mode of the stator and the external shell system respectively, and analyze the vibration of the motor. The results show that the performance of the designed permanent magnet servo motor can meet the operation requirements, which provides a certain guiding significance for the design and analysis of the servo motor
used in the intelligent inspection device of transmission lines.
