Getting Started with RMxprt

Rotational Machine Expert (RMxprt) is an interactive software package used for designing and

analyzing electrical machines.

Using RMxprt, you can simulate and analyze the following types of machines:

Three-phase and single-phaseinduction motors.

Three-phase synchronous motors and generators.

Brushless permanent-magnet DC motors.

Adjust-speed synchronous motors and generators.

Permanent-magnet DC motors.

Switched reluctance motors.

Line-start permanent-magnet synchronous motors.

Universal motors.

General DC motors and generators. Claw-pole alternators.

When you start a new model in RMxprt, you first select one of the above motor or generator types.

You then enter the parameters associated with that machine type in eachRMxprt Properties win-

dow.Theproperties windowsare accessed by clicking each of the machine elements (for example,

stator, rotor, shaft) under Machinein the project tree. General options are available directly at the

Machinelevel of the project tree. Solution and output options (such as the rated output power) are

Saving RMxprt Project Data Automatically

RMxprt stores recent actions you performed on the active project in an auto-save file in case a sud-

den workstation crash or other unexpected problem occurs. The auto-save file is stored in the same

directory as the project file and is named Projectn.rmpt.autoby default, where nis the order in

which the project was added to the current session. RMxprt automatically saves all data for the

project to the auto-save file, except solution data. By default, RMxprt automatically saves projectdata after every ten edits. An "edit" is any action you perform that changes data in the project or the

Warning Be sure to save machine models periodically. Saving frequently helps prevent the

loss of your work if a problem occurs. Although RMxprt has an "auto-save" feature,

it may not automatically save frequently enough for your needs.

design, including actions associated with project management, model creation, and solution analy-

sis.

With auto-save activated, after a problem occurs, you can choose to re-open the original

project file (Projectn.rmpt) in an effort to recover the solution data or to open the auto-save file.

To modify the auto-save settings:

1. Click Tools>Options>General Options.

The Optionsdialog box appears.

2. Under the Project Optionstab, verify that Do Autosaveis selected.

This option is selected by default.

3. In the Autosave intervalbox, enter the number of editsthat you want to occur between

automatic saves. By default, this option is set at 10.

4. Click OKto apply the specified auto-save settings.

Once the specified number of edits is carried out, a "model-only" save occurs. This means thatRMxprt does not save solutions data or clear any undo/redo history.

When RMxprt auto-saves, an ".auto" extension is appended to the original project file name.

For example, Project1.rmpt will automatically be saved as Projectn.rmpt.auto.

Recovering Project Data in an Auto-Save File

Recovering RMxprt Project Data in an Auto-Save File

Following a sudden workstation crash or other unexpected problem, you can recover the projectdata in its auto-save file.

To recover project data in an auto-save file, if RMxprt has unexpectedly crashed:

1. Launch RMxprt from your desktop.

2. Click File>Open,.

3. Select the original Projectn.rmpt project file for which you want to recover its Pro-

jectn.rmpt.auto auto-save file.

The Crash Recoverywindow appears, giving you the option to open the original project file

Note Auto-save alwaysincrements forward; therefore, even when you undo a command,

RMxprt counts it as an edit.

Warning When you close or rename a project, RMxprt deletes the auto-save file. RMxprt

assumes that you have saved any desired changes at this point.

Warning When you recover a project's auto-save file you cannotrecover any solutions data;

recovering an auto-save file means you will lose any solutions data that existed in

the original project file.

or the auto-save file.

4. Select Open project using autosave file to recover project data in the auto-save file, and then

clickOK. RMxprt replaces the original project file with the data in the auto-save file.

RMxprt immediately overwrites the original project file data with the auto-save file data,

removing the results directory (solutions data) from the original project file as it overwrites to

the auto-save file.

Periodic According to the geometric symmetry, the structure of electric machine

can be divided into several periods. The four pole electric machine in this

example has a whole slot number per pole per phase, therefore, it can be

divided into four periods. Choose the smaller period to shorten the run-

time for 2D Maxwell analyses.

Difference The angular displacement from the rotor to the stator in electric degrees.

Band Arc The air-gap is divided uniformly along the circumference. Band Arcisthe central angle corresponding to each division. The effective range of its

value is between 1oto 5o, the default value is 3o. In 2D electromagnetic

field analysis to the torque with 2D Maxwell, the value of Band Arcis

sensitive. The lower the value, the finer the air-gap meshes, the more

accurate the torque calculation, but longer the computation time in order.

Teeth to Teeth If you select this box, the central lines of the rotor teeth or the rotor

magnet poles coincide with the periodic dividing lines, otherwise, the

central lines of the rotor slots or the interpole lines of the rotor magnet

poles coincide with the periodic dividing line. Nevertheless, the central

lines of the stator teeth always coincide with the periodic dividing lines.
