Determining the source of noise in a motor is often much more challenging than correcting it. However, a methodical approach to investigating noise can narrow down the possible causes and therefore make resolution easier. This webcast addresses the causes and characteristics of the primary sources of noise in AC motors.

Learning objectives include the following:

• Possible sources of motor noise
• How to investigate motor noise
• Nature of magnetic, mechanical and windage noise
• Reducing noise intensity.
