Winding Bodies & Tool
• Feature: Design Modeler (DM) includes two new tools to allow a user to easily create current carrying coils: – Winding Bodies: Used to represent wound coils for source excitation. The advantage of these bodies is that they are not 3D CAD objects, and hence simplify modeling/meshing of winding structures. – Upon “attach to Simulation”, Winding Bodies are assigned as Conductor bodies. – Winding Tool: Used to create more complex coils for motor windings. The Winding Tool uses a Worksheet table format to drive the creation of multiply connected Winding Bodies. Or a user can read in a text file created by MSExcel.

Winding Tool
Complex coil windings may be created using the Winding Tool: • The Winding Tool inserts a “Winding#” into the model tree. • A “Details” view is used for geometric placement.
•
Fill Tool: Released at 9.0 (Beta at 8.1). Similar function to enclosure, but only fills interior cavities.
Example of a hemispherical enclosure around an electromagnet
– Up to 3 three symmetry planes can be specified.
– Full or partial models can be included in the Enclosure. – During the model transfer from DesignModeler to Simulation, the enclosure feature with symmetry planes forms two kinds of named selections: – Open Domain – Symmetry Plane

Winding Table File
• Each Winding has a Winding Table File associated with it. • The Winding Table File can be created directly in DM • The Winding Table File can be exported to or imported from a text file. • Each row corresponds to a created Winding Body
• A skew angle may be identified for the coil winding slots • Many motor designs employ a skewed coil form.

Fill Feature
• The Fill feature create a new frozen body to fill the space occupied by a hole or cavity. • Useful for interior cavity electromagnetic applications.
• Benefits: Very easy to use, rapid creation of coil windings.

Enclosure & Fill Tools
Design Modeler (DM) includes two features to allow a user to create a volumetric “field” body associated with a solid model. • Enclosure tool: Released at 8.0. This tool is used to completely enclose the bodies of a model in a material typically required for an Emag analysis.
