An Introduction to Noise and Vibration in Electric Motors

Electric motors and inverters cause noise and vibration, which arise from the switching frequencies and construction of the machines. Various decisions can be made to reduce this noise, but these choices will often affect the machine’s efficiency.

In this free, 60-minute webinar, HBK’s Mitch Marks will discuss basic noise mechanisms in electric machines and introduce NVH vocabulary for electrical engineers.

Key topics and takeaways:

• Learn about the numerous noise and vibration sources in electric machines
• Understand the electrical causes of noise and vibration
• Discover how to measure NVH and electrical signals
