Vincent CAPRON, CTO. POWERSYS
9:15 JMAG: Recent developments and roadmap
Dr. Takashi Yamada, JSOL Corporation
10:15 The electric machine designer in the 21st century
Professor Tim Miller
Abstract:
Will the electric machine designer of the future be a computer buff, dabbling in sophisticated apps on a smartphone? Or will he or she have strong and lithe thumbs from winding and re-winding weird prototypes in the test laboratory? Where will the new generation come from, and how will the species evolve from the slide-rule-pushing ancestors in tweed suits and brown lab-coats who gave us 90% of the electric machine technology we have today? How will they be helped by electronics, by materials science, by the internet? What will happen to the prototyping shop, if it hasn’t already happened? Can software really expand their capabilities, or will it limit the scope of their imagination? What challenges will they face, in addition to the changes in the supply of electrical energy, the much-touted revolution-to-come in automotive transport, the regulators and rule-makers, the scarcity of precious materials, and the escalating cost of software licences? Do the old and wise really have the best view of the future, or have they seen it all before? Is this keynote presentation really about electric machines at all? Yes!
10:40 Design and parametric modelling of a synchronous reluctance machine
Mr Marcel Lehr, Research assistant, Technical University Darmstadt
Abstract:
The presentation deals with the design of a synchronous reluctance machine for the use as an industrial drive with a power of 45 kW. For the design, a parametric Visual-Basic-Script (VBS) was implemented to create different models of the machine. Not only were several electromagnetic studies carried out with the help of this script but also mechanical and thermal studies. Due to the parametric modelling, the influence of the rotor parameters on different machine parameters (torque, losses, efficiency etc.) could be determined.
11:05 Coffee break
11:15 Optimization using JMAG
Sephan Paul, System development / Electrical drives & Battery systems (VT-S1), IAV.
Abstract:
Power and torque density are very important issues in design of electric motors for application in electric and hybrid electric vehicles. Permanent excited synchronous machines (PSM) seem to meet this requirement perfectly. Additionally, it uses a compact and robust design without slip rings. However, the permanent excitation has also some disadvantages as extensive no load losses at high speeds or high costs. During the design of an e-motor many boundary conditions have to be taken into account. Despite that the development has to focus on the strong requirements set by the costumer. For that purpose IAV uses JMAG in combination with its own optimization-tool. Using this toolchain IAV is able to optimize the electro-magnetic behavior and the mechanical strength of an e-motor within one optimization-process. This is very important to be able to maximize the flux utilization of the permanent magnets built into the rotor and to ensure the rotor can withstand the required maximum rotor-speed.
11:40 sunlight© pump – a small solar powered water pump developed using the JMAG toolchain
Prof. Dr. Andrea Vezzini, Head of BFH – CSEM Energy Storage Research Center – Biel – Switzerland
Abstract:
After using JMAG Designer and the optimization tool to design the motor and to calculate the motors efficiency map. This map is compared on a motor test bench.
Afterwards we used the JMAG RT Model together with the NI Electric Motor Simulation Toolkit to optimize the controller software. The system is set up as a HIL system, where the actual controller is connected to the FlexRIO FPGA Module and the inverter and motor are part of the simulated system.
This allows us to test the system in non-conventional working points and especially in failure points.
Development toolchain and results so far will be presented.
12:15 Network lunch
14:15 Design of interior permanent magnet synchronous motor
with JMAG-Designer and JMAG-RT

Kassem Roumani, Bergische Universitat Wuppertal
Abstract:
Recently, interior permanent magnet synchronous machines have been discussed as a possible candidate for hybrid and electrical vehicles. These type of synchronous machines offers high efficiency and high torque by utilizing both magnetic torque and reluctance torque. The reluctance torque caused by the saliency of the machine is used to improve the efficiency and to exploit the full power of the traction drive. Compared to the control strategy where the d-axis current is controlled to zero in the constant torque range, the maximum torque per ampere control strategy allows to produce a larger torque and to reduce the copper losses at the same output power condition.
14:40 Computation of Cogging torque with a non-cylindrical airgap
(Customer case from Powersys USA)

Eduardo Montalvo-Ortiz, JMAG Projects and Applications Engineer, POWERSYS USA
Abstract:
This presentation covers some several special cases that have been worked on for customers at the Powersys USA office in Southfield, MI. The first topic is an analysis for the computation of cogging torque for a slot-less PM motor with a non-cylindrical airgap when using a patch mesh. The second topic is handling loss information when creating a material in order to account for low stacking factors in the steel parts. Finally, a case is shown where stator inductance and resistance are computed for a motor model utilizing the results from an FQ study and compared to results obtained from JMAG’s built in inductance calculation tools.
