<h1>How to Protect and Maintain Electric Motors</h1><strong> Author: <a href='http://www.articleseen.com/profile_Ryan Hill.aspx'>Ryan Hill</a></strong><br /><p>Electric motor plays a vital role in the performance of the modern machines. It is responsible for the smooth performance of the machines. If the electric motors are maintained properly, then the machine can provide reliable service for several years. However, maintaining the motor is not an easy task because you need to frequently clean the motors. Always remember that electric motors are the heart of the machines. There are two types of threats such as external problems and internal faults in the motor that must be accounted while protecting the motors. External damages may be caused due to several reasons. Some important reasons are single phasing, unbalanced supply voltage, under-voltage, and reverse phase sequence starting. On the other hand, internal faults may occur due to internal faults, overload, and bearing failures. When overloading or prolonged operation on unbalanced supply voltage takes place then the first and foremost thing that gets damaged is the motor windings. Single phase operation and overloading are some of the faulty operations that cause the insulation of the motor to deteriorate until finally a fault occurs in the winding. Some effective tips that might help you to protect the motors from specific conditions are listed below: Overloading: This is one of the primary conditions that damage the motor. Furthermore, regular overloading reduces the lifespan of the motor. You can avoid overloading problems by strictly following the instructions that shows the maximum capacity of the motor. This problem mainly affects the windings which are very expensive. Friction: It is also an important contributing factor for the failure of the windings. If friction occurs, the motor puts additional efforts to restore which might damage the windings. So, use must use lubricants regularly for the smooth functioning of the motor. Heating: This occurs when the motor is used continuously for a longer period and when there are no cooling systems to get rid of the heat that is created due to the operation. However, thermal overload relay is used to determine the thermal capability of the motor. Do not exceed the limiting permissible value of bearing temperature. Maintenance: Regular maintenance is needed in the form of applying lubricating oil. You must also check the air coolers that are used to reduce the thermal heating of the motor. Examine the brushes and collector rings periodically because they are important for the effective functioning of the motor. Besides, if you need to perform electric motor repair then always opt for skilled professionals, because small faults that are left unchecked will cause severe damages to the motor. All these tips might assist you in maintaining the electric motors performance and lifespan efficiently. Most of the motor repairs take place due to mishandling and overloading, so while operating motors more care must be taken. </p><strong>About the Author:</strong><br /><a rel="nofollow" href="http://www.priestelectric.com">Electric motor repair</a> that are performed by experts will extend the lifespan of the motor for many more years.
