JMAG in Research and Development
2:10 am (7月29日) 10:10 am 1:10 pm Switched Reluctance Motor Design for a Forklift Traction Application
Berker Bilgin, Enedym/McMaster University
This presentation shows the design of a switched reluctance motor (SRM) for the traction motor of a forklift application. Design constraints and input parameters are defined according to the specifications of a forklift traction motor. Three-phase induction machines are commonly used for forklift propulsion systems. Several SRM configurations with a higher number of rotor poles than stator poles are designed to compare their characteristics and capabilities. Optimization of initial designs is performed using FEA and genetic algorithm-based controls optimization. The optimization goal is to achieve the design with the lowest volume and mass to increase the torque density and specific volume.
2:50 am (7月29日) 10:50 am 1:50 pm Simulation of a Variable Flux Machine in JMAG
Dwaipayan Barman, Concordia University
This presentation analyzes the electromagnetic simulation of a 27 slot 6 pole variable flux machine (VFM) using the JMAG software. The VFM uses AlNiCo9 magnets in which the magnetization level can be easily changed due to lower coercive force when compared to the rare-earth magnets. The magnetization and demagnetization of the VFM are performed using the JMAG software. The simulated back EMF and the electromagnetic torque of the VFM in JMAG software are analyzed at different magnetization levels.
3:20 am (7月29日) 11:20 am 2:20 pm Electric Machine Windings with Reduced Space Harmonic Content
Nanjun Tang, IIT Chicago
The reduction of space harmonics in the magnetomotive force (MMF) of electric machine windings has a primary role in improving the machine’s performance, contributing to a more sinusoidal voltage waveform, a smoother torque output, a higher power efficiency, etc. For a better understanding of winding MMF space harmonic behaviors and the effective suppression of the non-working components, a general analysis/design framework and several solution techniques are developed. Windings are designed in this study with the 5th- and the 7th-order space harmonics, and their associated higher order harmonics, simultaneously eliminated. The performance improvements of electric machines equipped with such a winding, including a more sinusoidal airgap magnetic field distribution and the torque ripple reduction, are verified by finite element analysis (FEA) simulations carried out with JMAG.
JMAG in Integrated Motor drive development
3:50 am (7月29日) 11:50 am 2:50 pm Integrated Motor Drive for Traction Application
Dr. Bulent Sarlioglu, WEMPEC
Prof. Bulent Sarlioglu will present the most recent research results to merge high-torque-density traction machines and high-efficiency inverters into state-of-the-art integrated motor drives (IMDs). This concept will package motor and power electronics inside combined housings that will exceed existing traction drive performance metrics in several categories. Several types of electric motors that are candidates for future land-based vehicle traction applications are evaluated. A high-performance surface permanent magnet (SPM) machine drive with a very high constant power speed ratio (CPSR) is proposed using a current source inverter (CSI) for a traction application. The voltage boosting feature of the CSI is investigated to improve the CSI-based SPM machine drive system’s overall efficiency in the constant power region. The integrated motor drive system’s operating characteristics are validated by 2-D finite-element analysis (FEA) simulations carried out.

Emerging Trends: JMAG in New Age Engineering
11:45 pm 7:45 am 10:45 am Keynote Speech
Tim Lambert, Hyperloop One
Virgin Hyperloop is developing the 5th mode of transportation, and actively building and testing at the component, subsystem, and system level. JMAG has been used throughout the design process for all of the active and passive electromagnetic systems, and continues to be valuable as the company delivers its product offering. Virgin Hyperloop is moving ahead in 2020 with customers and partners worldwide.
0:25 am (7月30日) 8:25 am 11:25 am Design and optimization of a high power density permanent magnet motor fabricated using cold spray additive manufacturing
Maged Ibrahim, NRC
A novel interior permanent magnet synchronous motor design comprising alternate layers of Permanent Magnet (PM) and Soft Magnetic Composite (SMC) was developed. The fabrication of the proposed design by cold spray additive manufacturing allows to eliminate the bridges and center-posts that are usually present in laminated interior PM rotors fabricated using conventional technologies. The layered rotor structure is optimized using JMAG optimization function. The resulting motor configuration has lower leakage flux and the absence of high stress regions in the design would allow to operate at higher speeds leading to higher power density. The optimized design can provide an output torque similar to a commercial V-shaped PM rotor while improving the motor efficiency especially at high speed-low torque conditions.
JMAG in Advanced Research Applications
1:05 am (7月30日) 9:05 am 12:05 pm Using JMAG to design a High Torque Density Halbach Rotor Coaxial Magnetic Gear
Dr. Bird/ Ho Yin (David) Wong, PSU
This presentation will present the design, analysis, and experimental testing results for a 5.67:1 Halbach rotor magnetic gearbox with a ferromagnetic back support. Using JMAG 3-D finite element analysis software the Halbach magnetic gearbox was calculated to achieve a volumetric torque density of 284N.m/L with only an active region outer diameter of 120mm. The experimental prototype obtained an active region volumetric torque density of 261.4N.m/L.
1:35 am (7月30日) 9:35 am 12:35 pm Design and Implementation of High-frequency Magnetic Components for Wired/Wireless Fast Charging Applications
Deepa Vincent & Huynh Sang, Ontario Tech University
The presentation will summarize the use of JMAG FEA simulations for electrified transportation and e-mobility fast charging applications. The modeling, design, analysis, and practical realization of both inductive and capacitive power transfer (IPT/CPT) for wireless charging will be presented. The HF AC-link coil construction and related EMI/EMC shielding design for varied IPT coupler designs will be presented. Furthermore, the capacitive plate design for CPT coupler interface and the influence of different dielectrics will also be presented. Finally, a HF transformer design to cater to isolation requirements in a universal on-board charger will also be highlighted.
JMAG MBD: A Better Approach to Motor Drive Development
2:15 am (7月30日) 10:15 am 1:15 pm JMAG RT
Ved Acharya, Powersys
Coming soon
2:45 am (7月30日) 10:45 am 1:45 pm Seamless Integration of JMAG and PSIM
Albert Dunford from Powersim & Ved Acharya, Powersys
Most electric motors can be easily modeled with linear RL components. These simple models can be used for most motor drive simulations. However, this simplification abstracts some important aspects of how real motors such as ripple effect, saturation, and spatial harmonics. PSIM and JMAG combine a Finite Element Analysis tool (FEA) simulation with a power electronics simulation to allow users to do more with simulation while reducing costs and development time.
3:20 am (7月30日) 11:20 am 2:20 pm A Better Way to Design and Test Motor Drives for EV’s
Ivan Celanovic & Petar Gartner, Typhoon HIL & Ved Acharya, Powersys
Automotive industry has widely accepted Model Based Design (MBD) for control software development; motivated by software’s safety critical nature and the need to comply with ISO 26262. The problem in the past was lack of ultra-high fidelity real-time Controller HIL (C-HIL) simulation of inverter and electric motor thus creating a gap in the workflow when evolving a model from Model in the Loop (MIL) and Software in the Loop (SIL) to C-HIL. In this talk we demonstrate Typhoon’s ultra-high fidelity motor drive HIL simulation with seamless integration with JMAG software. We will show a typical workflow for design and testing of EV drivetrain starting with JMAG FEA motor design, followed by export of spatial-harmonic PMSM motor model from JMAG-RT into Typhoon HIL simulation environment, followed by controller Hardware in the Loop simulation in Typhoon HIL HIL404 simulator interfaced with a real Engine Controller Unite (ECU) in the loop. Furthermore, we will briefly describe HIL interface towards […]
