The operation of the circuit currents refer directly to the fusion of an element by means of the Joule effect, which is duly caused by the sudden rise of current in a specific circuit. The fuse component has physical properties such that its melting point is less than the melting point of copper, and it is the most sought after material used in conductors of different applications. Therefore, through a transient resistance, the current becomes higher than the operating current. Thus, the equipment and part of the plant may undergo a thermal stress, ie, a short-time withstand current, or electrodynamic, which is an excess impulse rated current.
It is then concluded that circuitry refers to a connection without resistance, existing between conductors under voltage or in some cases can be considered as an intentional or accidental connection between two points of an electrical system or equipment, or an element , through an unsatisfactory impedance. Fuses refer to components used for the purpose of performing their main function, which is to limit the current of a circuit, providing its interruption in case of short circuits or long overloads. https://www.mrosupply.com/speed-reducers/motor-multiplier/223803_707069l_leeson/
It is important to note that the main purpose of the motor housing is to fix it in the working environment and protect it from external adversities in which it can be exposed where it will be properly applied. The motor housing is produced in such a way as to meet the different purposes of mechanical protection to ensure the requirements of the standards related to the installations and machinery for which the motors will be designed. It must be stated that the engines must be properly preserved and some specific care must be taken, both for the protection of those responsible for the service and against possible influences harmful to the engine, ensuring the safety requirements, and preventing accidents and fires.
In this way, the protection methods are used with the intention of promoting mechanical protection, since it fits into different categories. They are drip and splash proof, which are fully enclosed and explosion proof, all their rotating parts, or under tension, are preserved against dripping water from all directions, leaving no direct or indirect drops or drops. liquid particles or solid objects that spill over the engine.
Another category of protection consists of the fully enclosed motor, so that there is no possibility of exchange of the cooling medium between the exterior and the interior of the enclosure.
