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.
