2 Some people like to use SPUD to navigate the software - it isnt always necessary but we will start here:
3 At the center of all the SPEED software is the Motor Design program: Here you can select the Design program that you wish you use.
4 Also on SPUD there are links to: On Line Manuals: Material databases: (Steel, magnet and brush)
5 Finite element packages: - But lets start with the Motor Design.
6 Select and start a Motor Design program and obtain the Menu tool bar: Select New for a new design or Open an existing design – well start a New:
7 Choose from a standard example: The best way to proceed is to begin with one of the default designs or maybe one of your own designs that is close to the machine you wish to develop.
8 The Outline Editor shows the lamination and some basic dimensions:
9 Main menu: After Analysis: Results Consider the options in a logical order: Data Entry Analysis Tools
10 Data Entry Design data can be entered in various editors: The Outline Editor has already been mentioned.
11 The Template Editor (TED) for PC-BDC : All the parameters are conveniently organized. Page 1 is often sufficient to get started.
12 The Winding Editor is where the winding can be edited and various harmonics investigated:
13 Materials and magnets can be specified using the Materials dialog:
14 Click the right mouse button to find menu for View material: Saves time going through Materials and Magnet Databases when selecting.
15 Choose favorite units using the I/O Units: For fast use, many functions are available as Hotkeys:
17 To edit your Custom template select the template and pull the Editor|Options menu down on the toolbar: Add a variable name to list:
18 Analysis Whatever SPEED software is used there will be a variety of analysis or simulation options: Weve been using PC-BDC as an example so we have Static Design, Dynamic Design, Torque/Speed curves, Thermal analysis and Ranging facilities. Most of these are press-and-run though the Ranging needs setting up (well study that later).
28 The standard Design Sheet lists input and output parameters:
29 Data can be added to the Design Sheet using User Defined Formulas: Add rotor diameter:
30 At the bottom of the Design Sheet: The Help bar: This is permanent in the Design Sheet until edited or deleted.
31 Any variable can be Ranged by clicking on the right-hand mouse button when highlighting a parameter in TED… …over a number of steps by selecting the Ranging option on the analysis menu… (more than one variable can be ranged at one time – though this isnt 2-D ranging)
32 …giving a Design Sheet for each step…. Easy selection by clicking on variable with right-hand mouse button
33 … a very powerful tool (sometimes too powerful!). Ranging graph:
34 Create your own.DSS file for custom: To Set up your own Custom Design sheet:
35 Select the particular Custom Design sheet you wish to use: From the Option|General menu option:
36 Then your own Custom Design sheet is available: which can be copied to the clipboard and pasted as text into a word processor for your own use:
37 Tools There are many useful facilities in the Tools menu: The main ones are: Steel and Magnet Databases (direct access rather than going back to SPUD) FE Link (can be configured to bypass SPUD) FE Results Export Data
38 Calculator: OR Use the # sign in front of the Internal Parameter Index variable to extract the values, i.e., #piXXX:
39 Unit Converter: This is useful for refreshing your memory when switching between different units!
40 Scripting: SPEED software can now be interfaced with packages like Visual Basic: Select and load a.vbs file:
41 Execute the.vbs file: Results: This shows PC-BDC used as a blackbox procedure.
42 The Steel Editor and Comparator can be selected directly using Steel Databases for entering steel material data: …and inspecting characteristics.
43 Steel DBM facilities include loss calculation and parameter comparison:
44 Magnet Editor and Comparator can be selected in a similar way – functions include temperature effects:
45 FE Philosophy PC-FEA (Available soon for distributors customers) –Unique to SPEED Lab – integrated into software –Improves accuracy of particular SPEED calculations –Automatic SPEED procedures (GoFErs) Productivity External programs – Flux2D, OPERA, MAGNET –General purpose –Any geometry –Advanced problems Advanced analysis
46 Speed FEA Available soon to distributors customers PC-FEA is the SPEED Labs own finite element software designed to support the Motor Design. The FE Link allows several functions (GoFErs) to be carried out with a degree of automation. In PC-BDC, there are various GoFErs:
47 PC-IMD SPEED Procedures: PC-SRD SPEED Procedures: *PC-SRD is slightly different since there is a choice between Unimesh and PC-FEA.
48 Setting up the Mesh: The region nodes can be set up using the GDF editor. Editing may be necessary if the mesh is very large.
49 Running PC-FEA: The GDF editor generates a.FEA file which can be edited: The manual contains descriptions of the commands.
50 Some lines are more important than others: Increasing maxangle and maxpoints can help If youve edited the mesh in the GDF editor then you may wish to comment-out the Mesh Optimisation line because it may put all the nodes back! - if youre having problems then try not optimising anyway.
