Hybrid Excited Machine for Electric Vehicles Propulsion

The paper presents selected results of the 3D finite element analysis (3D-FEA) and experimental validations of a hybrid excited synchronous machine which contains magnetic barriers and permanent magnets inside the rotor. In the paper machine torque, no-load magnetic flux linkage, back-EMF, efficiency maps and field control (FC) characteristics have been presented and described. Moreover FC characteristics depending on machine DC control coil excitation have been estimated. Results of the 3D-FEA were compared with real measurements for validation purposes.
