The service life of electric motors is dependent on two (2) main components: Electrical components (i.e. windings & insulations); Mechanical components (i.e. core, shaft, bearings, frame and cooling system). The …
A Junction Box Is Required
In this article, I mentioned that a small change in the later stages of the project execution has a massive impact in cost and schedule. Another good example is what …
Open Circuit Faults
The majority of textbooks disregard open circuits when presenting unbalance faults in a power system. Almost always, only short-circuit faults are considered. In the following circuit diagrams, it is assumed …
Importance of Design Documentation
Design strategies should always allot time for design documentation. Almost always, this is the least priority in any project, may it be Engineering design or software design. Side Note: A …
