2 Conductor Types (1) The following types of parametric coil shaped conductors are available in Opera-3d: GSOLENOID Generally orientated solenoid. GRACETRACK Generally orientated racetrack. GBEDSTEAD Generally orientated bedstead. HELIX Helical end racetrack. CPEND Constant perimeter end racetrack. These are complete coils where the current circulates around the coil 3 Complete coils The geometry of these coils is defined by a simple set of parameters illustrated in the Opera- 3d Reference Manual and on the dialogs in the Modeller 4

3 Conductor Types (2) The following types of conductor building blocks are available in Opera-3d: GARC GSTRAIGHT BR8 BR20 Circular arc element with field tolerance Straight bar element with field tolerance 8 noded brick element. 20 noded brick element. These building blocks have current entering from one end and leaving at the opposite end The current density value is at the entry end 5 Building blocks The geometry of these coils is defined by a simple set of parameters illustrated in the Opera- 3d Reference Manual and on the dialogs in the Modeller The building blocks should be assembled to make a complete coil 6

4 Local coordinate systems Local coordinate systems are used to reposition conductors in space A local coordinate system is defined by the coordinates of its origin and three Euler angles to rotate the system Conductors have two local coordinate systems The first system allows the origin for the geometry parameters to be repositioned The second system allows further reorientation of the conductor in system 1 to give complete flexibility of position 7 Local Coordinate System 1 The local coordinate system 1 in the Modeller is a named local coordinate system created independently Applying a transform or copy to a conductor also creates a local coordinate system 1 8

5 Local Coordinate System 2 Local coordinate system 2 is formed by displacing the origin with respect to local coordinate system 1 by (X0, Y0, Z0), and rotating by Euler angles (Theta, Phi, Psi). X0,Y0,Z0 9 Symmetries and Reflections Conductors can have rotational symmetries SYMMETRY=n gives n copies of the basic shape each rotated by 360/n degrees about the global Z axis with respect to the previous copy. SYMM = 1 SYMM = 6 10

6 Symmetries and Reflections If n is negative then the sign of the current alternates from one copy to the next. SYMM = 6 SYMM = Symmetries and Reflections Conductors can also have reflections in the X Y, Y Z and Z X planes of local coordinate system 1. Parameters can be set to give no reflection, reflection with the same sign of current or reflection with the reverse sign of current. Inverse YZ plane reflection 12

7 Adding Coils to Circuits Circuits are constructed using the graphical circuit editor This allows a coil which has been defined as a circuit element to be included as part of the circuit See lecture 1-6 The circuit editor uses a drag and drop system to lay out the circuit Coils that are already defined appear in the Component Explorer Other circuit components are also available through the Component Explorer 13 Laying out a circuit Double clicking in the graphical space starts a wire Wires are horizontal or vertical One of each type can be drawn before the next double click 14

8 Laying out a circuit Drag and drop a component onto an existing wire The component name is created automatically Error messages are issued automatically until all data is complete 15 Laying out a circuit Click on the component name on the diagram, in the explorer or the error message to bring up the property menu Correct the errors by completing the missing properties 16

9 Laying out a circuit This circuit now includes winding W1 (one or more conductors) Conductors with the same circuit element name are in series 17 Including the circuit in the model When all the errors have been cleared, go to File -> Exit This will give the opportunity to: Accept the latest changes to the circuit and exit Will determine the circuit loop equations to be solved simultaneously with the electromagnetic equations Ignore the latest changes and leave the circuit as it was before the circuit editor started Continue using the circuit editor Circuits can be stored independently in.vfc files Allows exchange of data between models Script (COMI) files can also be generated 18
