- 11.00 am - 11.30 am: Keynote: Validation of FEA simulations of e-machines in traction applications by a sequence of defined measurements / achievable simulation accuracy | Dr. Hackmann, Vitesco Electrical machines in traction applications are operated in inverter-fed operation over wide speed ranges. The special demands on compactness and high efficiencies of those e-machines lead to high expectations on the FEA simulation accuracies. Here important aspects are described and a sequence of defined measurements for a proper correlation simulation / measurement proposed. In addition some practical examples are given.
- 11.30 am - 12.00 pm: Electrical steel and motor design synergy: Unveiling the benefits through a coupled analysis with JMAG | Ahmed Abouelyazied, Arcelor Mittal By incorporating higher-strength low-loss electrical steel (ES) grades in interior permanent magnet traction motors, designers can achieve optimal rotor design and notable energy savings. Thermal analysis plays a crucial role in estimating these savings, as lower heat loss mitigates winding resistance and minimizes permanent magnet degradation. A coupled electromagnetic-mechanical-thermal finite element model utilizing JMAG software reveals substantial temperature reduction when ArcelorMittal higher-strength low-loss ES grades are employed in stator and rotor cores. This leads to significant energy savings and the possibility of reducing rare-earth permanent magnet usage, depending on the specific design objectives.
- 12.00 pm - 12.30 pm: Reduced order model fidelity of PMSM using JMAG-RT | András Ujvari & Zsolt Varga, Rolls Royce The electrification of aircraft is playing a significant role in reducing the aviation industry's environmental footprint. The industry presents specific challenges to design engineers due to the design constraints. Developing an electric powertrain that meets the desired efficiency and power-to-weight ratio requires a multidisciplinary design approach to cover all design aspects. In an agile environment, different engineering teams work closely together to deliver the results. In these working environments, Model Based Design engineering can be the key to delivering the best system solution to the customer. For the permanent magnet synchronous machine, JMAG provides a powerful tool (JMAG RT) to generate low to high fidelity reduced order models for Simulink and Simscape, allowing engineers to make informed decisions about which model is most appropriate at different design phases.

The insulation system of the electric machine acts as an EMC transfer path that influences electromagnetic compatibility and safety as it can lead to increased parasitic capacitive coupling and sequentially, early failures of bearings due to bearing currents or electric discharges. The study proposes a multi-physics optimization approach that simultaneously targets performance, safety, and EMC objectives, integrating electromagnetic and electrical reliability considerations. The optimization considers electric machine geometries and their impact on parasitic capacitance, addressing EMC issues and enhancing the electric reliability of the e-machine.

Therefore, it is necessary to design electric machines with higher efficiency while keeping the cost limited. Thus, in this presentation, a multi-objective optimization of a permanent-magnet (PM) machine has been proposed considering the total losses and the cost of active materials as objective functions to minimise. For this study, a double-layer interior PM synchronuous machine has been selected. The machine has been initially designed using JMAG and the Multi-Objective Genetic Algorithm of the JMAG optimizer has been considered for the optimization. The different results as well as recommendations to use the optimizer efficiently when considering higher number of optimization parameters are presented and discussed.

- 11.00 am - 11.30 am: Ensuring the service life of winding systems in electrical machines at voltages up to 1500 V | Philipp Moritz, IAV The trend towards higher voltages is omnipresent in modern drive systems. As a result, the demands on the materials and insulation systems of the winding system are also constantly increasing. With electrostatic 2 and 3D JMAG simulations, the electric field strengths in the slot, at the slot exit and in the winding head can be calculated precisely and quickly. Due to the possibility to store all position information, the results can be transferred, discretized, scaled and the critical field lines can be determined by applying the Paschen curve. With this approach critical field areas can be quickly and easily identified and appropriate adjustments can be made to the insulation system.

PWM-effects on copper and iron losses must also be considered, especially at low-load operation.

Windings housed within stators of electrical machines are the central pivot of electromechanical energy conversion, operating at inherently higher temperatures due to DC and AC power losses, which to a large extent determine the motor power density level. The ever increasing requirements on power density and efficiency of electrical have prompted a revolution of winding technologies.
