This paper presents the design, modeling, and Finite Element (FE) analysis of a novel Electromagnetic Damper (ED). This cost-effective, regenerative ED is based on the concept of the tubular, linear, brushless dc motor. The structure of the proposed passive ED is straightforward, and it does not require an external power supply. An analytical model of the system is obtained using the magnetic circuit method and used to optimize the non-dimensional geometry factors and to estimate the electromagnetic forces and flux induced in the system. The model can be used to design high-performance dampers for various applications. To confirm the design, dynamic FE simulations were conducted and compared with the analytical and experimental results.
