Import PMSM Flux Linkage Data from JMAG-RT
This example shows how you can import a motor design from JMAG®-RT into a Simscape™ simulation.
Flux Linkage Data
The data file defining the motor flux linkage and torque is converted from a JMAG-RT model data file, 1k_S_C_IV.rtt, and is included in this example with permission of JSOL Corporation. JMAG-RT model data files are lookup tables for the magnetic flux and torque calculated using JMAG-Designer. You can convert a JMAG-RT model data file into a MATLAB® binary (*.mat) data file using the JMAG-RT Viewer (https://www.jmag-international.com/products/rt-viewer/). The details of this example motor, such as dimensions and rated power, are also accessible from the JMAG-RT Viewer. This example does not support generation of HDL code with sschdladvisor.

This plot shows the simulated motor currents and shaft torque when the rotor electrical angle leads the stator angle by 90 degrees. Notice the torque contains the harmonic components due to the slots and the magnetic saturation.
Results from Real-Time Simulation
This example has been tested on these platforms:
Speedgoat™ Performance real-time target machine with an Intel® 3.5 GHz i7 multi-core CPU and 4 GB RAM.
dSPACE® SCALEXIO LabBox with Intel® Core XEON E3-1275v3 at 3.5GHz and 4 GB RAM.
You can run this model in real time with a step size of 70 microseconds by using the Simscape local solver. For small sample rates, a task overrun might occur during the initial task execution due to a cold cache. To avoid this overrun, if the selected platform supports these options, relax the start-up behavior by specifying a limited number of task overruns or increasing the sample time of periodic tasks during the start-up phase of the real-time application.
