Rotational electric machines play a vital role in industrial facilities in order for them to be able to run continuously. The two most common types of machines used in industrial applications are the Induction motor and the asynchronous motor. Both types of motors are also used to operate various types of process equipment, including pumps, compressors, blowers, conveyors and many other heavy items.<\/span><\/p>\n

To mitigate unexpected failures as much as possible, the industry utilises RUL study analysis. <\/span>RUL study<\/span><\/a> refers to an estimation of how many years a motor can operate before it will reach its designated functional failure limit. The Remaining Useful Life of a motor is derived from current operating conditions, as well as current operational stresses, which predict how much useful service life remains in a motor based on the motor’s current working environment. A structured RUL Study will utilise a variety of data sources, such as inspection reports, diagnostic test results, historical data and analytical models to make a true-to-life estimate of a motor’s RUL.<\/span><\/p>\n

Why is an RUL Study important for motors?<\/h2>\n

A RUL study analysis of your motor is critical for enhancing the dependability and utilisation of your motors and decreasing the overall maintenance cost related to your motors.<\/span><\/b><\/p>\n

  • Prevent Unplanned Downtime<\/b>
    \nUnforeseen issues with an induction motor could result in the obstruction of production immediately. Unplanned downtime leads to the loss of production, inefficient use of labour and late or missed deliveries. The predictive nature of RUL predictions helps to provide advance notification of potential issues. The maintenance is, therefore, scheduled during previously planned shutdowns.<\/span><\/li>\n
  • Decrease the Maintenance Cost<\/b>
    \nUsing a time-based maintenance program may yield an overabundance of spare parts being replaced ahead of their useful life. In some instances, parts fail before they can be inspected and thus are not available for replacement. As you align your maintenance program to the actual conditions of the parts you are maintaining (RUL), unnecessary replacement is eliminated, and there are no emergency repair expenses.<\/span><\/li>\n
  • Increasing Safety<\/b>
    \nElectrical motor failure is a major reason for electrical fires and mechanical accidents so early identification through RUL Study protects personnel and facilities from fire hazards and accidents due to mechanical failures.<\/span><\/li>\n
