The challenging market in the e-mobility domain requires higher speed of development. To accelerate the time to market of the products, this phenomena is also addressing the tools and methods are used in the procedure of development. System simulations are widely used to control prototyping with validation purposes. Within a frame of a case study this paper presents the most common branches of the e-machine simulation methods. Highlights the main benefits and downsides of the simulation schemes. Draws results and sources from studies, are done in the field of finite element based e-machine modeling and simulation by the engineering community. These applications are evaluated and giving overview about the complexity of model structures, details and the computational sources from the perspective of required value of run-time. Explains the common approaches of the e-machine simulation methods, with an investigation in the field of hardware accelerated finite element analysis. Invests within the available studies and experiences from different non e-machine applications of the finite element method. Consequently notes a form of application and adaption of these techs of the finite element analysis that keep the tempo of development at a high-rate beside to offer a more detailed simulation than traditionally used tools for control prototyping purposes.
