TEAM Workshop No. 20 

Threedimensional, static electromagnetic calculation. As an example, the
TEAM Workshop No. 20
is calculated. This model is also available for download in the examples distribution.


The flux density distribution of TEAM Workshop No. 20

2D Transient Calculation of an Induction Machine 

Geometry plot of an induction machine with squirrel cage. 

The finite element mesh. 

The magnetic vector potential. As it can be seen, it is a machine with two pole pairs. 

Isolines of the magnetic vector potential. 

Flux density distribution in the induction machine at load operation. 

Force density at the stator teeth. The calculated machine has an
eccentrically positioned rotor, resulting in a asymmetric force
density distribution. 
Switched Reluctance Machine (SRM) 

Quarter model of an SRM with skewed rotor. The excited coil is shown in red. 

A cut plane through the model is introduced. 

The flux through the tooth  by integration over the tooth cut plane the flux linkage can be determined.
All these steps can be performed with the post processing capabilities of iMOOSE.trinity. 

Spherical Motor 

Quite large model of an experimental spherical motor with permanent magnets (green and red).
Coil windings and air regions are not shown. 

Flux density distribution arising only from the permanent magnets. 

Clawpole Alternator 

High quality picture of a clawpole alternator with translucent air regions. 

Same as above but also the surface mesh is shown. 

Flux density on the stator 

Partitioned FE mesh for parallel computation on six cluster nodes with iMOOSE.stat3dpar.

Induction Heating 

Large movie to illustrate the model of a transversal induction heating device for thin strips.
While the largest part of the model is needed to solve the electromagnetic problem, an thermal problem
must be solved on the strip even it is part of the electromagnetic mesh. For efficiency reason in case of parallel
computation different partition schemes must be applied on the thermal and electromagnetic problems.
