Title:  Soft magnetic material characterization in JMAG

Today engineers who working in the electrification industry (EV, Aerouspace, energy…), pushing their electrical machine design towards the highest efficiency and power to weight ratio to increase the range of the vehicle, or maximize the power generation with the given kinetic energy where the machine is intended to use. Feeding the proper material data into the simulation software is a key step for accurate results. Soft magnetic material characteristics are depend on multiple parameters including measurement capabilities (frequency and magnetic flux range of the measurement amplifier), and manufacturing processes like cutting technology and assembly process of the active and passive parts (stator/rotor core housing/shaft fixation). JMAG offers advanced material models to incorporate mechanical stress and residual strain materials during simulation. During this seminar these modelling techniques will be introduced and will be compared with measurement results.

Title:  Simulation technique to simulate power electronics effect on the electrical machine performance

Today engineers who working in the electrification industry (EV, Aerouspace, energy…), pushing their electrical drive train design towards the highest efficiency and power to weight ratio to increase the range of the vehicle or maximize the power generation with the given kinetic energy where the drive train (Power electronics and electrical machines) is intended to use. Choosing the optimum PWM modulation method and switching frequency is a key to optimize the drive train efficiency. Lower switching frequencies and DPWM modulation techniques significantly reduce the power electronics losses but have negative effect on NVH and loss performance on the electrical machine. In this seminar advanced simulation technique will be presented based on Simba system and power electronics simulation and JMAG FEA simulation and the coupling capabilities of these tools.

Title: Ansys CFD Thermal Analysis and Workflow Optimization for Electric Motor Design

This session presents a simulation-based workflow for three-dimensional Conjugate Heat Transfer (CHT) and Computational Fluid Dynamics (CFD) thermal analysis in electric motor design. The methodology integrates rapid pre-design tools with high-fidelity 3D solvers. The workflow establishes a data pathway where an optimized configuration from Ansys Motor-CAD is transferred into Ansys Discovery and Fluent.  The electric motor is modelled in MotorCAD following a 2d template approach. Firstly, the electromagnetic performance of an operating point of the machine is analysed to extract the losses on the different components. These losses will then be used to evaluate the final temperatures of the machine as well as the change of temperatures with the passing of time, where the impact of different cooling strategies will be evaluated. Secondly, the effects of the raise in temperature on the machine performance will be studied over the full machine operating range and how they affect the different operating points. Finally, the changes in the machine temperature will be studied not only for a simple operating point, but rather during a more complex duty cycle.

Title: Ansys CFD Thermal Analysis and Workflow Optimization for Electric Motor Design

This session presents a simulation-based workflow for three-dimensional Conjugate Heat Transfer (CHT) and Computational Fluid Dynamics (CFD) thermal analysis in electric motor design. The methodology integrates rapid pre-design tools with high-fidelity 3D solvers. The workflow establishes a data pathway where an optimized configuration from Ansys Motor-CAD is transferred into Ansys Discovery and Fluent. To handle geometric complexity efficiently, grid generation guidelines—including parallel poly-hexcore meshing and local face-sizing for thin air gaps—are applied. The double-precision, pressure-based coupled solver incorporates specific physics modeling to capture localized hotspots and non-uniform material behavior. This includes introducing volumetric loss source terms, resolving rotation via a Moving Reference Frame (MRF), and utilizing cylindrical orthotropic thermal conductivity for stator components. Additionally, a customized curvilinear coordinate system is showcased to precisely model heat transfer across complex stranded coils and end windings. Finally, the substitution of homogenized parameters with anisotropic thermal properties is demonstrated, highlighting a significant reduction in prediction errors against reference validation data.

Title: HIL for e-Mobility: Accelerating e-Drive Development from Design to Real-Time Testing

Electric powertrains and e-Drives are transforming how we design, test, build, and operate vehicles. Electric vehicles are powered by software, with Power electronics, control units, and communication systems playing a pivotal role in seamlessly integrating hardware and software. In this context, the design, development, and lifecycle maintenance of digital controllers have become increasingly complex. Traditional development approaches, often fragmented and siloed, are resource-intensive and prone to inefficiencies, late-stage issue discovery, costly design iterations, and integration challenges. Robust and continuous testing, enabled by specialized benches, real-time simulation, and advanced modeling tools, offers a future-proof response to these challenges. This workshop invites professors, students, and researchers to explore how Model-Based Engineering (MBE) and Hardware-in-the-Loop (HIL) testing streamline the design, validation, and implementation of control and optimization strategies for electric powertrains and e-Drive applications. The session will demonstrate how to move from offline simulation to real controller implementation while preserving model continuity across the development cycle. We will walk through the complete development workflow using Typhoon HIL’s Integrated Toolchain, emphasizing the use of MIL, SIL, and C-HIL simulation approaches, along with test automation, to enhance development efficiency. A practical example will be presented: starting with initial design in TyphoonSim™, progressing through automatic code generation for microcontrollers, and concluding with real-time validation using HIL testing. In addition to this, experience from previous Summer School lectures will be utilized during the hands-on part.
