By the above processing, divided model data for calculating the torque is created.

In the division model creation process, first, the first step (C1, C2, C3 above) of automatically creating the division model of the minimum unit area in the two-dimensional plane, the created model in the two-dimensional plane The second step (C4) of automatically creating a complete two-dimensional model by duplication using symmetry, etc., and the three-dimensional model is automatically created by stretching the created two-dimensional model in the direction perpendicular to the plane.

When the torque result is read by reading the file, all the names of the read torque result file are displayed in L31. At this time, a number indicating the order starting from 1 is added to the head of each result name (this number is called a result number). L31 is a list menu in which a plurality of items can be selected, and the user selects a result desired to be displayed as a graph from the list menu.

Which graph out of four kinds of L21 is drawn: rotor rotational position (angle) x torque, parameter x torque, rotor rotational position (angle) x axial force, parameter x axial force. Is a pull-down menu for selecting one.

L11 to L14 are all buttons for displaying a graph. Rotor rotation position (angle) x L21
When torque or rotor rotation position (angle) x force acting in the axial direction is selected, it is necessary to plot multiple result curves, but there are four buttons depending on the way this plot is displayed in different colors according to the results. There is.

L11 displays all plots in black. At L12, the result of L31 is plotted in the order selected by the user by allocating colors having a predetermined order. In L13, plotting is performed by allocating colors in a predetermined order from the ascending order of the result numbers selected by the user. In L14, plotting is performed by allocating colors in a predetermined order in accordance with the result number of the result selected by the user.

L41 is an input field that can be accepted only when the parameter x torque and the parameter x force acting in the axial direction are selected in L21, and sets the parameter value of each result displayed in L31. .

As a default for this parameter value, a numerical value included in the file name may be set.

L51 is the minimum value on the horizontal axis of the graph to be drawn,

It is read in 04. Although only one torque result file is read here, a plurality of torque result files Q02 can be read at the same time.

The graphing GUI module P03 will be described below.
The procedure when the user displays a graph will be described using.

(G1) File L0 in the main menu
The screen of FIG. 24 is displayed by 1, the directory having the result is set in M01, the result to be read is selected from M03, and the result is read by pressing the OK button.

(G2) Use L31 to select the result to be displayed.

(G3) Use L21 to select the format of the graph to be displayed.

(G4) If the parameter x torque or parameter x axial force is selected in L21,
Since L41 is ready for input as shown in FIG. 25,
Set L41 as required. Note that when L21 is set to rotor rotational position (angle) × torque, or rotor rotational position (angle) × force acting in the axial direction, FIG.
As shown, the L41 is in an input impossible state.

(G5) Press one of the buttons L11 to L14. As a result, when L21 is set to the rotor rotational position (angle) × torque or the rotor rotational position (angle) × force acting in the axial direction, a change in the rotational position of the rotor such as L51 in FIG. A graph of the resulting torque or axial force change is plotted for each result (three curves are plotted because in this example three results were selected). When L21 is set to parameter × torque or parameter × force acting in the axial direction, three graphs of changes in torque or the axial force acting due to the difference in the result files, such as N11 in FIG. Is drawn.

Here, three lines are drawn, that is, the maximum value, the minimum value, and the average value. The value on the horizontal axis of the graph of FIG. 25 is the parameter value set in L41 for each result.

The user may select L51 and L5 as necessary.
After setting 2, the drawing buttons L11 to L14 are pressed.

(Example 2) In Example 1, the width of the outer magnetic pole of the stator was set equal to the angle obtained by dividing 360 ° by the number of poles of the magnet. Further, the width of the outer magnetic pole is not changed in the axial direction. However, in practice, it has been found that the width and shape of the outer magnetic pole have a great influence on the torque characteristics. Therefore, by inserting the data of the width of the root of the outer magnetic pole and the width of the tip portion into the data of the stator shape shown in FIG. 15, a more detailed study of the motor performance can be performed.

Further, it is known that the cogging torque can be suppressed by subtly shifting the circumferential arrangement of the A-phase and B-phase stators (Japanese Patent Laid-Open No. 11-308841). By including the shift amount in the above parameters, more detailed performance study becomes possible.

As will be easily understood, the parameters given here can be input during the division model creation. Specifically, the model of D19 and D2 in FIG.
Between the 0 button and the button to change the magnetic pole width, A, B
A button is provided to slightly shift the arrangement of the phase stators. This makes it possible to study more important shape parameters.

However, depending on the case, there are many cases where it is desired to execute a large amount of these continuously. Therefore, here, these modules are independently executable programs.

That is, each module is made into a program having the name shown in FIG. 27 (command name when executed from the command line), and necessary arguments are added from the command line so that it can be executed. And as shown in Example 1,
When a button is pressed from the interactive screen to execute each module, a predetermined argument is added in each core GUI module and these programs are started from within the module.

By doing so, these modules can be executed interactively or independently from the command line. This makes it possible to continuously execute these programs (modules) as a command procedure, which is very convenient for the user.

Further, as shown in FIGS. 7 and 16, the names of the buttons for executing these modules are the names of these modules to which a brief description is added. This saves the user from having to remember the module name when running from the command line, making it very easy to use.
