JMAG-Express Power mode

JMAG-Express Power mode is a design tool that allows you to perform motor design and evaluation by simply inputting parameters, like geometry, winding, and rotation speed, that follow a template.
It utilizes the finite element method's highly accurate analysis ability to evaluate eddy current losses in magnets and iron losses from local magnetic saturation or harmonic currents.
JMAG-Express Power mode also supports more detailed design studies by seamlessly using models and results from JMAG-Designer, the electromagnetic field analysis software.

Features

JMAG-Express Power mode delivers highly accurate results with simple settings

• Simply input the design parameters for geometry, materials, winding, and drive conditions.
• The design parameters are limited to the essentials, and are intuitively easy to understand.
• No prior analysis knowledge is necessary.
• It automatically carries out the process from analysis model creation to results output.

It evaluates efficiency maps and losses from magnetic saturation and harmonic current, which are essential to a motor's performance analysis.

• Magnetic flux density distribution or iron loss density distribution
• Joule loss frequency analysis
• Magnet eddy current loss distribution
• Efficiency maps

Getting a more detailed study by seamlessly connecting with JMAG-Designer or a control circuit simulator

• Start up JMAG-Designer by clicking the calculation result screen.
• Generate an RT model while maintaining the design parameters.

Main functions

Freely define geometry templates

• Templates for PMSMs, induction motors, brush motors, and universal motors have all been prepared.
• You can add geometries created in JMAG-Designer as templates.
• JMAG-Express Power mode can evaluate the motor characteristics of PMSMs and induction motors. Use JMAG-Designer for brush motors and universal motors.

Built-in database

• You can search for model data by design parameters, output, and design date from a wealth of design proposals.
  E.g. Searching for model data where the slot combination is 4 poles and 24 slots
  - Search model data where the average torque is over 3 Nm
  - Search model data that was calculated on May 25, 2012
  
  

Geometry sizing

• JMAG-Express Power mode will recommend a geometry and drive conditions if you simply enter the minimum output expected of the motor.
• Of course, you can also narrow down the geometry and drive conditions by entering more information.

An extensive material database

• JMAG-Express Power mode has approximately 700 items of characteristics data built-in, just like JMAG-Designer.
• Precise material designs are completed by selecting the material name.

Running the analysis remotely

• You can use an external calculation server.
  E.g. When there are a lot of analysis cases
  

Saving and reading setting parameter files

• You can save setting parameter files separately from geometry data.
• This should come in handy during system automations like linking with opimization softwares.
