Motors – Mechanical Protection

Electric motors must be preserved, taking into account the protection of the persons performing the service, as well as external influences that may be harmful, and it is extremely important to consider all safety and accident and fire prevention requirements.

The motor housing has the purpose of securing it in the workplace, ensuring the protection of the same, according to the local environment where it will be installed. The casing must be designed in such a way as to encompass the different types of mechanical protection, in order to promote compliance with the requirements of the plant and machinery standards for which the engines will be designed.

In this way, the mechanical protections can be classified into three categories, they are resistant to drips and splashes, completely closed and explosion proof.

TE2533433S

Engines resistant to dripping with all rotating parts, or under tension, are protected against water. In fully enclosed motors there is no exchange of the cooling medium between the exterior and the interior of the enclosure. And the explosion proof are built for service in environments saturated with gases and dust. Its enclosure is resistant to explosions of gases or explosive mixtures specified inside, preventing a surrounding flammable atmosphere from being ignited.
