This is the high-speed, high-precision FEA software tool at the core of JMAG.
An intuitive interface and precise modeling technology with a wide variety of results displays are built in.
Multifaceted evaluation of various design ideas is made possible by freely manipulating geometry, material properties, and drive conditions.


JMAG-Express is a motor design tool.
Instantly calculates the motor performance as a calculator and provides design sheets to meet its requirements.
It enables to review all design changes accumulated in JMAG-Express at any time just as though you were referring to design memos.

JMAG-Express Online

JMAG-Express Online is a parameter-based motor design support tool.

The Web version of JMAG-Express, which can compute basic motor characteristics in 1 sec, has finally arrived!

It is possible to obtain in an instant the startup voltage constant, torque constant, inductance characteristics, current vs torque characteristics, rotation speed vs torque characteristics, iron loss/copper loss characteristics, etc. merely by inputting a geometry template, materials, windings, and drive conditions.

Because JMAG-Express Online can be used with tablets and smartphones, you can design motors anytime, anywhere, on the go or at home.


JMAG-RT generates a high fidelity plant model. Since the model is still numerically based, it can solve very quickly. And since it is based on Finite Element Model results, it will not sacrifice accuracy to achieve this calculation speed. The JMAG-RT plant model can be used in system level simulations to provide a more accurate representation of the electromagnetic device. The JMAG-RT block can be used in Hardware in the Loop Simulations (HILS) which connect a physical Electronic Control Unit (ECU) to a virtual motor.

JMAG-RT Viewer

The JMAG-RT Viewer is an application to increase the usability of motor models created using JMAG-RT. The motor models created using JMAG-RT (JMAG-RT models) can be used in control simulators such as Simulink to reproduce phenomena including the nonlinear characteristics and torque variations of motors.

Speed versus torque curves and efficiency maps can be created by specifying the control mode for the JMAG-RT model in the JMAG-RT Viewer. Creating an efficiency map regardless of whether measured or obtained as analysis results is an extremely laborious considering the multitude of measurements/calculations and data that needs to be processed. However, the contents of the JMAG-RT motor model can be confirmed without utilizing the model in Simulink. Control designers can gain a overview of the motor features easily and motor designers can confirm the motor characteristics of their designs.
