The cable wound VHV (Very High Voltage) synchronous machine is a new machine type directly driven by a HVDC-Light inverter and is used on oil platforms. However, in order to find more cost-effective designs, a design tool is necessary.  In this thesis work, a FEM model for cable synchronous machines is developed. Python language has been used to model and mesh the geometry under the Flux2D FEM environment. Delphi is used to control the simulation flow. The thesis work includes software design, coding and debugging according to requirements. The model has been tested on a typical design of a cable synchronous machine designed by ABB Machines, Västerås. Additionally, the model has been integrated in the ABB simulation program, SynFEM, which is a FEM platform for different analysis, such as magnetostatics, time-stepping, and thermal calculations, for synchronous machines. This integration made it easier and more efficient to use the VHV model in the designer's environment.  To achieve the above, the accumulated knowledge on different computer languages, simulation platforms, and machines is required. To build this model which has a more complicated stator geometry compared to conventional stators is also timeconsuming.  This report includes the main files of the VHV machine model and some simulation results of both magnetostatics and time-stepping simulations.
