다중 권선형 솔레노이드 코일에 작용하는 전자기적 팽창력 해석

다국어 초록 (Multilingual Abstract)

The solenoid coil is one of the most important design component for efficient electrical energy conversion in the structure of electric machines such as motors, generators, and transformers. When the current is applied to a multi-turn solenoid coil, a uniform magnetic field which is proportional to the number of coil windings is generated inside the coil, and the high-density magnetic field generated by the coil can be converted into mechanical kinetic energy by applying the strong electromagnetic force to a ferromagnetic object. However, the interaction between the current and magnetic field of the solenoid coil generates a strong electromagnetic force between each coil wire. In this paper, when the current flows in the multi-turn solenoid coil, the analysis method and numerical equation for calculating the electromagnetic expansion force generated in the radial direction of a multi-turn solenoid coil are proposed. Calculated results are verified by simulated ones.
