内容
9:30 am 4:30 pm Welcome Note / User Conference Introduction
10:00 am 5:00 pm Development planning of JMAG | Dr Takashi YAMADA, JSOL Corporation
JMAG is constantly being worked on to achieve highly accurate and high-speed simulation. JSOL would like to share our progress from the past year including parallel solvers to accelerate speed as well as GUI improvements aiming for increased productivity of analysis workflow. Analysis technologies we are currently focusing on and our plans for incorporation will also be covered in this presentation. Design exploration is an important topic this year. This presentation will detail the present and future of JMAG.
10:45 am 5:45 pm Coffee break
11:15 am 6:15 pm Keynote: Design and Control of E-Motors for E-mobility Applications | Shafigh Nategh, Polestar
The presentation will focus on different aspects of E-motor design and control where JMAG tool-chain has a major contribution.
11:45 am 6:45 pm Transient Failure Modes of IPM Motors in Electric Vehicle Applications | Bernd Cebulski, IAV GmbH
EV Motors driven by voltage source inverters can suffer from a variety of different failure mechanisms. Some of them will influence the functional safety behavior of the entire drive system. Others will compromise performance and efficiency or lead to excessive noise. Some failure modes are also accompanied by additional heat due to specific losses. The simulation of these failures incorporate specific inverter reactions as well as machine characteristics. The simulation with JMAG therefore needs to reflect the control system reaction and the transient magnetic operation of the stator-rotor parts. The paper will provide some approaches and examples of failure simulations coupling JMAG with the inverter control reaction.
12:15 pm 7:15 pm High power/torque density in trapezoidal RFPMSM (radial flux permanent magnet synchronous machines) | Alex Stepuk, EVR Motors
This paper presents a strategy to increase power and torque density in a novel proprietary trapezoidal topology of RFPMSM (radial flux permanent magnet synchronous machines) for In-wheel and automotive applications. Comparative express 2D and 3D simulations performed to select the best formed square slot soft magnetic composite (SMC) stator. Higher fill factor of concentrated winding allowed to increase power density of machines even for their air cooling configurations, Results of sImulations were validated on in-house test-bench and demonstrated good accuracy with experiments.
12:45 pm 7:45 pm Lunch break
2:15 pm 9:15 pm Electrical machine loss simulation and model validation using JMAG and MATLAB Simulink | Zoltan Nadudvari, Rolls Royce
The electrification of aircraft is playing a significant role on the path to reduce the aviation industry’s environmental footprint. The industry poses specific challenges for the development engineers due to the strict requirements and design boundary conditions. Developing an electrical drive train which meets the high safety standards, the desired efficiency and power to weight ratio requires a multidisciplinary design approach to cover all of the requirements and design aspects. In an agile environment different engineering teams often use different platforms / ecosystems (e.g. Matlab, Simcenter, JMAG) to deliver the results in time and face the challenge of real-time simulation and test data exchange between the disciplines. The aerospace industry set the highest standards to the engineer regarding the design process and also for validation and verification the design results. In RRE-HU we were able to develop a process to simulate the power electronics effect on the electrical machine at the earliest phase of the design by connecting JMAG and MATLAB-Simulink. A prototype electrical machine was built and tested and the test results – focusing on the losses - were compared with the simulation results for model variation both in case of sinusoidal and PWM load.
2:45 pm 9:45 pm Development of high performance traction motors with advanced hairpin windings Based on Jmag-Designer | Tianjie Zhou, University of Nottingham
The rapidly increasing demand on power density levels of electric vehicle (EV) drive systems is pushing the boundaries of traction motor performance. Hairpin windings are becoming a popular option for EV motors due to their reduced DC losses and improved heat dissipation capability when compared to traditional random windings. The presentation will be about how JMAG is utilized for layout design and conductor size optimization of hairpin windings in a typical traction PM motor.
3:15 pm 10:15 pm Coffee break

5:00 pm 12:00 am Coming soon | Vilmos Paiss, Robert Bosch

9:15 am 4:15 pm Coming soon | Andreas Carlsson, Polestar
9:45 am 4:45 pm Concept of PCB Motor for Fan Applications with Ferrite Core | Shahin Asgari, TU Graz
Small (up to five watt) brushless permanent magnet motors require low complexity for high-volume manufacture and cost reduction. This present aims to reduce complexity, cost, and component count of such drives by proposing a new low-cost three-phase axial flux permanent magnet motor topology for fan applications based on a PCB instead of a conventional winding. Also, a high number of pole pairs and a ferrite core are used in the structure to increase efficiency and torque density. The motor’s design is explained in detail and, for proof of concept, investigations in the no-load and load conditions are performed using finite element analyses. In addition, important design considerations are discussed. The findings confirm the practicality of the proposed low-cost and straightforward motor topology.
10:15 am 5:15 pm Zooming method for litz wire stator | Robin Krüger, Mercedes-Benz AG
Coming soon
10:45 am 5:45 pm Coffee break

11:45 am 6:45 pm Simplified power electronics for the control of a switched reluctance linear motor for hyperloop and container handling applications | Guillermo Regidor, Zeleros
The decarbonization needs of ports have produced a growing demand for electrical systems for cargo transport. Using the same technology that is being developed for Hyperloop, we propose the use of linear motors as an automated solution with zero direct emissions. In this conference we will discuss the validation in JMAG of the control and dynamics of a linear switched reluctance motor, including electromagnetic analysis of the whole machine, linear movement and power electronics simplification.
