Simulation & calculation

ENGIRO is characterised by its own development and manufacturing of electric motors.

It starts with initial design studies, geometric pre-dimensioning, modular concepts and shifting designs for different operating parameters. Subsequently, the solution versions are supported further by simulating and optimising electromagnetic properties, mechanical and thermal optimisation as well as coordination with different power electronics. Finally, all production-ready documents, test specifications and documents are created.

An essential tool for designing and optimising our highly efficient electric drives is the numerical magnetic field calculation. In the theoretical stage, the finite-element method (FEM) is used to design the way the magnetic fields are formed and to calculate how magnets and coils must be arranged under certain boundary conditions in order to optimise the magnetic field lines for specific applications. For these FE-calculations we use the programs like ANSYS, Infolytica and others.

The simulation calculation also covers operating strategies. Here, logical relationships are run through to simulate energy management in particular. We carry out these calculations using the program Matlab Simulink.

ANSYS is used for mechanical and dynamic calculations, e.g. to optimise rotors under centrifugal force, to safely transmit torques or to avoid resonance.

Fluid calculations with superimposed heat transfer are carried out using FloEFD at our sister company ISATEC.
