3D - transient finite element analysis of transverse flux machine for mobile platform with external circuit connection and electromechanical coupling

Transient finite element analysis of a flux concentrated permanent magnet transverse flux machine (FCPM-TFM) that is designed to be incorporated as in-wheel motor for a mobile platform using FLUX3D, a 3D-finite element (FE-) package from Cedrat with external circuit connections and electromechanical coupling features, is presented in this paper. Two magneto-dynamic studies of transient analysis are performed. The first study is achieved as the rotor moves at a constant imposed speed so that the harmonies are considered through the motion. The initial values are estimated from 3D-magnetostatic simulations. The second transient study involves electromechanical coupling so that the dynamic behavior of the motor can be investigated. The later analysis is achieved by starting the motor at no-load until it approaches a steady speed. The practical results are consistent with the theoretical expectations.
