When electric motors drive your business, it is important to make sure that they are fully operational at any given time. Like any piece of mechanical equipment, however, there are issues that can occur which would result in electric motor failure and perhaps some significant downtime in your operation. Being able to identify the early warning signs of electric motor failure allows you to head off many of the problems before they occur. Here are five different issues that you should watch for.
Electric Motor Running Hot
One of the most common issues that can result in motor failure is if the electric motor is continually running hot. In many cases, a problem with a hot running motor is self-induced and results from too much lubrication being applied.
Although providing adequate lubrication is important for the operation of the motor, providing too much causes it to overheat and significantly shortens the life of the unit. Be sure that you pay attention to the proper maintenance of the unit in order to provide adequate lubrication without overdoing it.
Sludge in the Reservoir
When lubrication is added to the electric motor, it is important to add the proper type of lubricating oil and to continue to use it consistently. Mixing different types of lubrication results in the sludge that shows up at the bottom of the reservoir.
Another issue that could result is a reaction that occurs between water and the detergents in the unit. This can result in soap sludge, which can shorten the lifespan as well. If it is necessary for you to clean the electric motor with water, ensure that the breathers and fill caps are in place before cleaning. Oxidation is another reason sludge can show up in the bottom of the reservoir. Having the oil analyzed to determine if it is breaking down may help to avoid this problem.
Excessive Energy Usage
Although there are a number of ways to determine if an electric motor is about to fail, it can often be seen in an excess usage of energy. This issue may occur for a number of different reasons including the use of synthetic lubricants or if the motor is running hot. If you notice a spike in energy usage or if you have one motor that is consistently using more energy, it is a good idea to provide the necessary maintenance so that you can avoid an expensive repair bill.
Excessive heat is always going to be a problem and it will likely shorten the lifespan of the electric motor considerably. One of the areas that can experience an increase in heat is the gearbox. One common reason the gearbox may be running hot is if there is a problem with the lubricant. Perhaps the lubricant isn’t topped off to the proper level or you may be using the wrong lubricant viscosity. If you notice that there is a lot of dirt that is on the gearbox, it can also result in excessive heat because it doesn’t allow the heat to escape properly.
