Each drive unit begins with pure mathematics. Before even a single wire winding is pulled in, we perform countless calculations. This precision has always determined what we do. But good can always be made better.
Since February, we have therefore been using FEMAG-ME as a new and additional calculation program. The electrical design can now be used as the basis for deriving mechanical parameters faster and more easily. Especially in high-frequency drives, the exact determination of centrifugal forces, elongations, joint pressures and pressings is critical.
Faster to the exact value
With FEMAG-ME, the mechanical deformations and tensions can be calculated in a two-dimensional model. Particularly advantageous is the adoption of models that were produced using other FEMAG modules. In this way, the mechanical strength of the design can be verified immediately after the magnetic layout of the machine. The load produced by centrifugal forces can thus be arrived at from the speed, virtually at the press of a button. The elongations of the individual subsections can also be determined for different temperatures. For press fits, the overlap is entered in the unconnected condition. The program then determines the joint pressing in the connected condition.
See what happens
For the given loads, FEMAG-ME calculates the deformation of the model. The mechanical tensions are derived from this. Various tension hypotheses are available for the evaluation.
Last but not least, the new program also enables a modal analysis of the model. In this way, the expected noise level can be assessed at an early stage by determining the natural frequencies and characteristic vectors.
All in all, FEMGA-ME allows an even more precise layout of drives – for greatly reduced development times and costs. Good for us. Good for our customers.
