The maintenance of The The maintenance of any electric equipment requires much planning and inspecting. The potential breakdowns of any machinery is only discovered though planned and periodic inspections.  An observant workforce can help identify problems with machinery. The smell of burning insulation, excess heat in bearings, unusual sounds or vibrations, mechanical flaws and sparks, etc. can be diagnosed through an early inspection of the machinery by an expert workforce.

The operation of electric motors can be controlled through certain devices called motor controls. Motor controls have a number of critical functions, including starting and stopping the electric motor, moving forward or reversing the path of rotation, selecting and regulating the speed of rotation, controlling or modifying the torque/force, and protecting the motor against electrical overloads and errors. Monitor control command sets (MCCS) have evolved, through the years, from cabinets with basic electromechanical devices like circuit breakers, contactors and overload relays, to computerized centres that include variable frequency drives.

To help you improve the performance of your electric motors, we have enlisted some noteworthy tips below:


Infrared thermography is a non-invasive form of inspection which employs an infrared camera to observe the temperature and thermal patterns when the equipment functions at full load. A varied range of machinery, including MCCS uses infrared thermography to function and it is also helpful in predicting equipment breakdowns and planning corrective actions. It can also be used to detect various electrical fault conditions such as loose connections, hot spots, poor contacts, unbalanced loads, overloading and overheating. Safety is the most important aspect when it comes to handling electrical equipment. Just one careless step and you could put your life in danger. The personnel must always follow proper safety measures and wear personal protective gear before engaging in any work related to electrical equipment.


A lot more training is required for this type of maintenance than just visual examinations. Engineers must follow specific guidelines for de-energizing, isolating and preparing the equipment for inspection. This mainly includes inspecting and repairing equipment before placing it back into service. It is also necessary to verify that whether the replaced equipment has the correct rating and is suitable for the application or not.


In case of any error, excessive current may damage the MCCS structure, components, bus or conductors. If a fault occurs, all the required equipment should be disconnected and isolated to prevent contact with live components. It is also very important to confirm whether the power has been cut off or not.

The life of your electric motors depends a great deal on proper maintenance. It can trace potential problems and correct them before a massive breakdown or delay in production. Hence, saving you from any major collapse. Make sure to always follow the manufacturer’s guidelines for maintaining the equipment, lubricating the motor bearings and keeping the motor running smoothly. Also, be sure that your equipment is well-ventilated and confirm the right voltage and current when performing maintenance checks on your motors to get satisfactory results.
