Clawpole alternators have suffiuciently complex geometries that they require a full 3D analysis, including the effects of motion. Symmetry and periodicity can be used to reduce the size of the final simulation model. Heating effects during operation are included by solving a coupled analysis along with the thermal module, Simcenter MAGNET Thermal.

Short circuit force calculation and Open circuit analysis. Losses in Busbars, Stray losses and Eddy current losses, Voltage discharge, Skin Effect. Lightning strike analysis, Ion Drift Effects, Winding losses, Magnetic and Electrostatic analysis coupled with Thermal, Impulse voltage distribution, Transformer cooling system analysis, including fluid dynamics in oil tanks. Such calculation is available in all types of transformers.

Modelling of electromagnetic actuators in a systems context is sometimes required to accurately simulate the dynamic interaction between drive circuit, actuator, and the load. Examples showing actuator design utilising Response Surface Modelling are included, as well as full transient with motion modelling.

Loudspeakers are another kind of actuator, and some examples specific to loudspeaker design are included. These include optimising a design (to minimise its mass), and using the mechanical equations of motion to obtain the performance charts for a sample loudspeaker.

To model induction heating applications, it is necessary to have a close coupling with a Thermal analysis software. In the example presented, Simcenter MAGNET Thermal is used to model the temperature rise, including when the temperature increases beyond the Curie temperature. A second example shows how a coupled Simcenter MAGNET / Simcenter MAGNET Thermal model can be optimised using the Simcenter MAGNET Design Optimisation software.

Eddy current non-destructive testing/evaluation (NDT/NDE) examples are included, showing optimisation strategies, as well as some meshing techniques that are useful for improving the accuracy for crack detection modelling.

Applications ranging from surge arrestors, transformer bushings, and electrostatic precipitators are included here, using the Simcenter MAGNET Electric analysis package.

Many other devices can be modelled, including Magnetic Gears, MagLev systems, Magnetrons etc. Effectively any electromagnetic device can be modelled using the software tools available.
