In a serious situation, the damage of an electric motor partially or totally paralyzes an industrial process where it is installed, and needing the importance of it may have extreme consequences for the industry and third parties, generally involving heavy economic expenses.
In these cases, the malfunction is usually identified through a corrective maintenance action, however there are less obvious cases where failure occurs that gradually worsens with time and is only detectable when the performance is strongly affected or there is an evident manifestation of failure , Through an atypical behavior of the operating conditions. This is usually the scenario in most industries, which do not have a maintenance plan that invests in prevention, but merely fixes what has already deteriorated.
To prevent these events from occurring, some companies carry out a preventive inspection of the state of the machines working in their complexes, through an in-depth analysis of operation or even a disassembly to qualify their structural state. The expense associated with this maintenance action varies from location, time, and sometimes inaccessible situations where they occur, and will represent a respectable percentage of all company expenses. https://www.mrosupply.com/speed-reducers/worm-gear-reducer/2299329_237q56r50_morse/
