Earthing is a fundamental step in any electrical system installation. Its proper installation also depends on the proper functioning and safety of equipment and people, as it protects against potential differences that can be dangerous in both cases. Why it is so vital, how to set up a project correctly and what regulations must be followed to install the earthing system...
Motors produce torque and rotation through the interaction of magnetic fields in the rotor and the stator. In an ideal motor — with mechanical components that are perfectly machined and assembled and electrical fields that build and decay instantaneously — torque output would be perfectly smooth, with no variations. But in the real world, there are a variety of factors t...
Speaking of aluminum alloys, everyone is not unfamiliar, and it can be seen everywhere in life; but aluminum enclosure may be heard less often, so what are aluminum alloy case? Today we will talk about it. What's Aluminum alloy Aluminum alloy is an alloy based on aluminum with a certain amount of other alloying elements added. It is one of the light metal materials. In ...
Backlash: The enemy of linear systems Backlash is caused by clearance, or play, between mating parts, which introduces a dead band when the direction of travel is reversed. In the dead band, no movement occurs until the clearance between mating parts is eliminated. Components that typically experience backlash include ball screws, lead screws, belt and pulley systems, ...

Electrical hazards can cause electrification (or electrocution) as well as burns with serious injuries or even amputations. Working on electrical installations exposes you to the risk of an electric arc. The thermal impact of an arc depends not only on the voltage level (LV/HV) but also on the incident electrical energy (cal/cm²). Effective and appropriate personal prote...
The presence of uncontrolled quantities of air in water systems can seriously affect their performance, causing inefficient filling and draining procedures and flow reduction, while increasing energy costs. It also disrupts the operation of some of the system’s components. On the other hand, air is essential in dealing with vacuum conditions and pressure surges. Effecti...
