Broken down generator sets can usually be taken to your regular electric motor repairs centre for rehabilitation, a process that usually involves replacing eroded and burnt out parts, with the complexity of the project depending upon the specific condition of the generator set. Generators can sometimes be fixed simply with the help of a problem solving kit that targets the most common problems that occur over time and extended usage.

Larger generator sets, however, often require a more in depth approach. This involves checking for cracks on parts under significant load pressure, and detailed electric motor repairs to parts such as the rotor and gears. These processes are always three-fold, as the mechanic first identifies the problem causing the generator to work under standard or break down completely, then fixes the problem by replacing, patching or reconditioning parts and finally makes recommendations on preventing the problem in the future.

Sometimes the problem with the generator can be improved or solved by changing other parts of machinery that support and work with the generator. Electric motor repairs such as these involve analysing the power capacities and requirements of the generator set, and checking all parts for compatibility. This is important because machinery that is designed to work with a low power generator will quickly burn out under pressure the pressure of a high voltage power supply. Selecting the right generator and parts for your particular application is essential to saving money and time in the long run.

Often the nature of the electric motor repairs required will change according to the application the generator is used for. Hobbyists and enthusiasts often use generators in unconventional ways to achieve new results, making a certain degree of experimentation necessary when it comes to fixing a broken down machine. These unconventional methods can include using high tech, light weight lithium batteries in electric cars, to provide more power and increase the potential speed of the vehicle.

Sometimes, when a generator set is working below par, all that is needed is a simple clean and reapplication of lubricant to the machine. These are the most simple of electric motor repairs, but also the most essential in the long run. Dust and debris caught in a generator set can be heated to extremely high temperatures, causing it to combust and possibly cause a disastrous explosion. Lubrication is also important to all mechanical processes as it can prevent friction between machine parts, thereby extending the operational life of the machine.
