For the design of an inductive power and data transfer electromagnetic calculation are carried out. A transfer system is considered for loads that are distributed across some distances. For example, such loads are adjustable speed drives that are found in factory automation and intra-logistic. Physical properties of the inductive transfer are modeled via COMSOL. Lumped parameters are deduced from magneto static and quasi static calculations. Selected operating conditions are investigated with combined field and network calculations. Field calculations are 2D and 3D and they are carried out for stationary and in the frequency domain. Also heating is modeled at a basic level. Results are compared to experiments that are carried out at a purpose built test stand
