Initial experimental verification of a compact permanent magnet transverse flux machine in a sector configuration

Flux concentrated permanent magnet transverse flux machine (FCPM-TFM) that is designed to achieve a compact design for in-wheel applications, has been set under test experiments to verify the published investigations that are demonstrated in and achieved through many computer simulations via using FLUX3D, a 3D finite element (FE-) package from Cedrat. The study in this paper includes generator and motor operations of the FCPM-TFM. Starting with generator electromotive force i.e., back EMF test, where the machine is operated as a generator for different speeds. The induced voltage waveform and cogging torque have been estimated via introducing 2D grids in certain positions of a two pole pitch segment and compared to the outcome of the software. The flux linkage has been examined by using an AC method, while including core losses, where the effects of saliency are illustrated. Motor operation is done through full block control. The measured quantities have been compared to the simulations results.
