Import a Motor-CAD Thermal Model into Simulink and Simscape

Overview

You can use this project to import an Ansys™ Motor-CAD™ motor model into Simulink®.

You can use the automatically-generated Simulink model to:

• Predict the transient temperature of the motor elements under dynamic operating points and diverse cooling scenarios.
• Run simulations faster than real time.
• Integrate the motor in a system-level model using Simscape™.
• Analize the performance of your system design in a holistic way.

This project is compatible with MATLAB R2021b or newer, and with multiple versions of Motor-CAD.

Use the links below to download the latest version, depending on your Motor-CAD version:

• For Motor-CAD 2024R2 or newer (with PyMotorCAD interface): Use Download button above
• For Motor-CAD 15.1.6 or newer (with Visual Basic ActiveX interface): MotorCAD_v15.1.6.zip

1. Import a Motor-CAD model into MATLAB

You can use the Object-Oriented MATLAB® - Motor-CAD interface (included in this repository) to import a Motor-CAD model into MATLAB and easily modify motor properties and run Motor-CAD calculations.

For more information, run >> doc mcadinterface.ThermalInterface

2. Generate a Simulink Reduced-Order Thermal Model (SROTM)

Run the GenerateSimulinkThermalModel.mlx live script to automatically generate the SROTM for an induction motor (IM) and a permanent magnet synchronous motor (PMSM).

The IM has one active cooling system (housing water jacket). It is based on the e5_eMobility_IM Motor-CAD template.

The PMSM has two active cooling systems (housing water jacket and through-ventilation). It is based on the e8_eMobility_IPM Motor-CAD template.

3. Validate the SROTM

Run the ValidateSimulinkThermalModel.mlx live script to compare the SROTM simulation results with the Motor-CAD simulation results at different operating points.

4. Use the SROTM in Simscape Models

Run the UseSimulinkThermalModel.mlx live script to simulate a Simscape system-level vehicle model that integrates the Simulink reduced-order thermal model of the motor.

Setup

Open the project file ImportMotorCADThermalModel.prj to get started.
