JMAG's Proposed Model Based Development
JMAG-RT enables model based development with high concurrency, allowing plant design andcontrol design to be performed concurrently. JMAG-RT is a system which generates high-fidelity
plant models (JMAG-RT models) in a system level simulation from FEA models. From system design,
to ECU verification using HILS, JMAG-RT has a wide range of uses.

FeaturesUsing a virtual device model in HILS means that it is possible to test the ECU while the device is still underconstruction. This can reduce the amount of test time necessary on the actual test bench.
Conceal information about geometries or materials so it can be shared between business companies.
The JMAG-RT model captures device performance that includes non-linear effects, saturation, and spaceharmonics. This high fidelity modelʼs response is nearly identical to the actual deviceʼs response.
FEM-Parameterized PMSM Block Support: Use JMAG-RT models with Simulink and Simscape.

How to Create JMAG-RT Models
・JMAG's finite element method (FEM) analysis allows the model creation even without an actual machine.
・Also possible from actual measurement values of the motor.
・Plant models can also be obtained from the JMAG-RT motor model library.
・JMAG-RT Viewer can even create and display inductance and other characteristic maps.
