| Sunday, May 18 | 8:00 AM - 11:30 AM | Magnolia 2 | Tutorial 1: Multiphysics Equivalent Circuit Modeling for Electric Machinery -- From Macro-scale to Micro-scale | N/A | Peng Han, Manager Application Engineering, Ansys |
| Monday, May 19 | 5:30 PM - 7:00 PM | Azalea Ballroom | Poster: Motor Noise and Vibration Simulation Accuracy Improvement via Modal Parameter Tuning | Noise, Vibration, and Harshness (NVH) are critical factors in the design and performance of electric motors. Excessive NVH can lead to reduced product life, increased maintenance costs, and customer dissatisfaction. Addressing NVH challenges early in the design stage is crucial to avoid major NVH issues in the later design stage. Ansys Motor-CAD employs analytical methods that enable fast NVH analysis. However, stator stiffness calculation may be limited in certain cases due to the simplification of the stator shape into a basic ring in the analytical model. This paper discusses how to improve NVH simulation accuracy by tuning modal parameters, which are obtained from either simulation or test. The validity of the proposed method is verified through simulation using full finite element analysis (FEA). | Shi-Uk Chung, Senior Application Engineer, Ansys |
| Wednesday, May 21 | 10:30 AM - 12:10 PM | Magnolia 2 | Oral: Electromagnetic Modeling of Lattice Structures in Additively Manufactured Electric Machines | Recent advancements in metal additive manufacturing (AM) show great potential to revolutionize the design and manufacturing of electromagnetic components used in the field of electrical engineering. Lattice structures directly printed by AM processes typically offer better structural performance with reduced weight, such as high stiffness, surface area, elongation, energy absorption, and porosity, than the solid counterpart. This paper aims to study the electromagnetic modeling of lattice structures used in additively manufactured magnetic cores or windings for electric machines. Three dimensional (3D) electromagnetic finite element (FE) analysis with high performance computing (HPC) shows the highest fidelity in predicting the electromagnetic performance of designs with lattice structures by preserving complex geometry details. FE-based homogenization methods have also been explored to potentially speed up concept design. A case study based on an additively manufactured axial-flux permanent magnet machine with a Hilbert pattern stator validates the discussed electromagnetic modeling approaches. | Peng Han, Manager Application Engineering, Ansys |
