Understanding Eccentricity Effects on Stator Tooth Forces for eNVH Analysis

Eccentricity is a critical factor in the performance and efficiency of permanent magnet motors. It refers to the displacement of the rotor's axis from the center of the stator. Even small deviations can have significant consequences, impacting the motor operation and leading to electromagnetic noise, vibration, and harshness (eNVH). Understanding the effects of eccentricity and effectively analyzing its impact on motor behavior is crucial for optimizing motor designs and ensuring reliable performance.

In this webinar, we will provide a comprehensive understanding of eccentricity - static, dynamic, and mixed types and its effects on motor operation. Using the powerful EMWorks2D software, we will guide you through the quick process of simulating a permanent magnet synchronous motor (PMSM) model with different eccentricity scenarios. Moreover, we will focus on the computation and comparison of tooth forces affected by eccentricity. By studying these forces, we gain a deeper understanding of how eccentricity influences motor performance under varying conditions. To enhance the learning experience, the webinar will include interactive demonstrations of the simulation software, showcasing its capabilities and enabling attendees to explore and analyze the effects of eccentricity.
