2. Electromagnetic shielding - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_shielding

   Common sheet metals for shielding include copper, brass, nickel, silver, steel, and tin. Shielding effectiveness, that is, how well a shield reflects or absorbs/suppresses electromagnetic radiation, is affected by the physical properties of the metal. These may include conductivity, solderability, permeability, thickness, and weight.

3. Electrical steel - Wikipedia

   en.wikipedia.org/wiki/Electrical_steel

   The typical relative permeability (μ r) of electrical steel is 4,000-38,000 times that of vacuum, compared to 1.003-1800 for stainless steel. [ 15 ] [ 16 ] [ 17 ] The magnetic properties of electrical steel are dependent on heat treatment , as increasing the average crystal size decreases the hysteresis loss.

4. EN 62262 - Wikipedia

   en.wikipedia.org/wiki/EN_62262

   The European Standard EN 62262 — the equivalent of international standard IEC 62262 (2002) — relates to IK (impact protection) ratings. [1] This is an international numeric classification for the degrees of protection provided by enclosures for electrical equipment against external mechanical impacts.

5. Brush (electric) - Wikipedia

   en.wikipedia.org/wiki/Brush_(electric)

   A pair of carbon brushes. A brush or carbon brush is an electrical contact, often made from specially prepared carbon, which conducts current between stationary and rotating parts (the latter most commonly being a rotating shaft) of an electrical machine. [1] Typical applications include electric motors, alternators and electric generators. The ...

6. Faraday cage - Wikipedia

   en.wikipedia.org/wiki/Faraday_cage

   Faraday cages cannot block stable or slowly varying magnetic fields, such as the Earth's magnetic field (a compass will still work inside one). To a large degree, however, they shield the interior from external electromagnetic radiation if the conductor is thick enough and any holes are significantly smaller than the wavelength of the

7. Commutator (electric) - Wikipedia

   en.wikipedia.org/wiki/Commutator_(electric)

   Also, the high resistance brush was not constructed like a brush but in the form of a carbon block with a curved face to match the shape of the commutator. The high resistance or carbon brush is made large enough that it is significantly wider than the insulating segment that it spans (and on large machines may often span two insulating segments).

8. Armature (electrical) - Wikipedia

   en.wikipedia.org/wiki/Armature_(electrical)

   When the machine or motor is used as a motor, this EMF opposes the armature current, and the armature converts electrical power to mechanical power in the form of torque, and transfers it via the shaft. When the machine is used as a generator, the armature EMF drives the armature current, and the shaft's movement is converted to electrical power.

9. Brushed metal - Wikipedia

   en.wikipedia.org/wiki/Brushed_metal

   Brushed stainless steel or dull polished metal [1] is metal with a unidirectional satin finish. It is produced by polishing the metal with a 120–180 grit belt or wheel then softening with an 80–120 grit greaseless compound or a medium non-woven abrasive belt or pad. Commonly brushed metals include stainless steel, aluminium and nickel.
