Learning How to Use JMAG


Basic Curriculum

How-To (1) Basic Operations and the Concept of Modeling

Start by using the tutorial; Self Learning System (SLS) to study the operations and analysis flow in JMAG.
Refer to the key points in each procedure which describes the concept of “why the settings are set the way they are” in modeling.

Case Study Steps to Study
Motor PM Motor > 2D Analysis Up to STEP 11
PM Motor > 3D Analysis Up to STEP 8
Induction Motor Up to STEP 8
Transformer Transformer > Transformer Analysis Up to STEP 8
Linear Actuator Solenoid Valve Up to STEP 7 or STEP 11
Induction Heating Induction Heating Up to STEP 16
Sensor Sensor Up to STEP 7
Wireless Power Transfer Wireless Power Transfer Up to STEP 9
  • STEP 1 of SLS is about creating the geometry. If you are using CAD models, start from STEP 2.
  • The program can also be started from the Windows menu. Click the Windows button, and select [JMAG-Designer] > [Self Learning System].

How-To (2) Working on your own assignments

Once you get to know the basic operations in JMAG, you can start working on your own assignments.
JMAG has substantial technical material for use in finding solutions.
Refer to them when you are not sure about the concept of modeling or when using new functions.
We hope you will find them useful in finding solutions.

The JMAG Application Catalog
Learn how to create models for each of your objectives using applications.
The Application Catalog is a collection of JMAG analysis examples.

The Application Note (explanations) and model data are provided.
The concept of condition settings is described in detail in the Application Note.

E.g.) How is the time interval determined?
  ・What should the number of divisions around the circumference be?
  ・What kind of settings are required to account for eddy current?

Find one that is similar to what you are working on and use it as a reference to create an analysis model.

  • How to view the catalog
    Select [Help] > [Application Catalog] in the JMAG-Designer menu bar.
