What are harmonics in industrial applications? Any takers on this?

Here's a standard definition for electrical harmonics. A harmonic is a whole number multiple of a fundamental frequency.

The square waves used in motor drives produce high-frequency harmonics, even though the main goal is to produce low-frequency sine waves. These harmonics can be harmful to industrial electronics (including AC and DC motor windings) and cause excess radiated energy that interferes with nearby electronics. Chokes, filters, and line reactors are  used to suppress the transmission of harmonics in an electronic system.
