| Abstract: | The external energy tubular weapon realizes the automatic cycle through the motor drive, and the dynamic performance of the motor directly determines the technical and tactical indexes of the weapon equipment under high impact load.Based on the analysis of the working characteristics of the external energy tubular weapon and its short intermittent system, the special motor design is carried out with high electric load.The electromagnetic simulation model of permanent magnet synchronous motor was established under different electrical loads, and the power density and temperature rise of the motor were compared and analyzed. The optimal design of the motor structure under high electrical loads was carried out with the aim of reducing the motor torque fluctuation. The results show that under the conditions of satisfying the parameters of the combat indicators of the weapon and the temperature rise, compared with conventional electric load motors, the mass of high load motors is reduced by 28.85%, and the power density is increased by 28.78%; Before and after structural optimization, the torque fluctuation of the high load motor was reduced by 2.21%. The results show that in view of the working characteristics of the short intermittent system of the transfer weapon, increasing the electrical load on the premise of satisfying the performance indicators is conducive to the miniaturization design of the weapon system. |
