Considering EMC: Essential in Today's Designs

In today’s high demand for technological advancements, Electro-Magnetic Compatibility (EMC) plays a pivotal role. As designs become more powerful, efficient, and low-profile, they also become highly dense, necessitating a keen awareness of EMC considerations.

1. Understanding EMC: EMI and EMS

EMC can be broken down into two critical aspects:

Electro Magnetic Interference (EMI): This refers to the ability of electronic devices not to interfere with other nearby electronics. Imagine annoying lines on your television screen or instrument malfunctions during a commercial flight—these are classic examples of EMI-related issues.

Electro Magnetic Susceptibility (EMS): On the flip side, EMS pertains to a device’s ability to remain unaffected by other electronics in its vicinity. For instance, pilots strongly advise against using large electronic devices during take-off and landing to avoid potential interference.

2. Where EMC Matters

The impact of EMC extends across various domains:

Residential: Think of the frustrating interference on your home entertainment systems due to neighboring electronic devices.

Medical: In healthcare settings, sensitive medical equipment must function flawlessly without being disrupted by nearby electronics.

Aeronautical: Commercial airplanes rely on precise electronic systems, and any EMC-related glitches could compromise safety.

3. Cooling Fans and EMC

Even cooling fans are not immune to EMC challenges. Here’s why it matters:

EMS and Corrosion: EMS can lead to electric corrosion in fan bearings which reduces the lifespan of the fan and increases physical noise and current. Strong discharges of electromagnetic noise are created by high power and frequency devices. These discharges penetrate through the bearing grease and allow current to pass through the bearing ball. As the ball rotates within the bearing during these discharges of noise, undulating wear appears on the rotating surface of the ball. In this abnormal state of the ball, the bearing will make unwanted audible noise and vibration in operation.

4. SANYO DENKI’s EMC Solutions
