Simulation-Based Noise and Vibration Analysis of an Interior Permanent Magnet Synchronous Motor

Issah Ibrahim, EMaG Specialist, Maya HTT

This presentation investigates a combined electromagnetic, structural, and acoustic simulation-based process of an Interior Permanent-Magnet Synchronous Motor (IPMSM). Acoustic noise is a result of a rotating magnetic flux wherein harmonic interactions build up magnetic pressure inside the airgap. The magnetic pressure causes vibrations in the stator core, which propagates to the outside as acoustic noise. The goal is to explore the acoustic space of the IPMSM through detailed design and simulation process using finite element solutions. We extend the analysis to explore the largest feasible design space of the IPMSM. Rather than restricting the analysis to a few motor designs, we use competent FEA software to fully understand the acoustic field around thousands of motor geometries. Attendees will discover how to use the finite element method with fully coupled, data-driven multiphysics simulations, without having to build thousands of motors to choose the optimal design.

Issah Ibrahim is an EMaG specialist at Maya HTT. He holds a PhD in Electrical Engineering. His research interests include the development of numerical analysis tools such as the finite element method, the design and optimization of low-frequency electromagnetic devices with particular emphasis on electric motors, generators, actuators and transformers plus their coupling to power electronic drives, as well as their thermal, structural and vibro-acoustic analysis. His work at Maya HTT involves offering technical support to customers using software products in the Siemens Simcenter portfolio, particularly MAGNET, MOTORSOLVE, and SPEED in the design and optimization of low-frequency electromagnetic devices.
