짐벌 시스템 적용을 위한 토크 모터 설계 기법 연구

Abstract

According to the information released by the World's Technology Research Trend Center (2014), the demand for drones is drastically increasing and it shows a very positive outlook for market development possibilities. One of the essential pieces of high necessary for these drones is the camera gimbal system, which is used for obtaining high quality images. The normally used gimbal system materializes two degrees of freedom using motors; the author uses this thesis to propose that replacing the designed torque motor can make the machine’s structure and control method easier. This thesis uses the performance of the SPMSM model (that had been studied as an initial motor for gimbals as the standard), and uses the finite element analysis program to design torque motors. By comparing the two models’ structure and control method, it shows the advantages of torque motors and the validity of gimbal systems. Based on the physical phenomenon of torque, a basic model’s shape was designed, and a final model was selected using the finite element analysis program and mathmetical optimization technique - Response Surface Method. With the finite element analysis results, standard SPMSM and torque motors’ performances were compared, with the advantages and disadvantages of torque motors are discussed. Based on the data presented through the thesis, recommendations are set forth for torque motors’ research approach.
