eMotoren Berechnung und Simulation

Calculation and simulation

State-of-the-art simulation tools ensure that technology is protected in our client projects.

The Advance Development department works out specifications for mechanical construction and for developing power electronics. The Calculation department specialists design active components based on the client's specifications.
Another aim is the analysis of the system as a whole.

  • design and calculation of drives
  • electromagnetic calculation
  • determining heat development
  • calculating fluid mechanics
  • thermal calculation
  • vibration calculation
  • rotor dynamics
  • Simulation and analysis of entire systems
    • system simulations (electromagnetic circuits, thermal behavior, mechanics, electronics)
    • system efficiency factors

With the FEM calculation procedures at our disposal, we are able to establish and describe the behavior of electrical machines with great accuracy. This allows us to efficiently forecast, at a higher modeling level, the subsequent operating behavior of both individual components and the system as a whole.

Further examples include determining dynamic losses, along with the associated heat development, calculating fluid mechanics for designing the cooler, and calculating vibration, for determining noise behavior.


In addition, the latest magnetic materials are investigated, and plans made for their use in future development projects.

The department has state-of-the-art numerical and analytical calculation options available, such as the finite element programs (FEM), Maxwell and Ansys Mechanical. Simulations of systems are carried out using MATLAB/Simulink or Simplorer.

Ongoing comparison of simulations to measurements on our dynamometers means that the department has years of experience with a wide range of motor technologies.
