electric motor failure occurs due to overheating, phase unbalance, voltage unbalance, single-phasing, surge voltages, poor ventilation, lack of lubrication, overloads, over cycling, excessive moisture, improper belt tension, misalignment and vibration, loose connections, pests, etc. incorrect electric motor selection for the application and motor defects can also cause motor failure.
bearings are a critical element of electric motors. they facilitate even load handling, reduce friction, provide shaft support, and enhance the reliability and longevity of rotating components. however, without proper installation, operation, and maintenance, bearings can become damaged or fail. here, we’ll go over some of the most common causes…
electric motor failure can be caused by a variety of factors, ranging from simple wear and tear to more complex issues related to power surges or voltage drops. the most common root causes of electric motor failure incl...
most of the electric motor failures occur at the start up. most of them are caused by the over-heating of motor. there are also other factors which greatly affect the performance of electric motors such as low resistance, dirt, moisture, over-current and vibrations. electric motors should be installed very carefully and should be looked after at regular intervals.
in this article, we will learn the most common general reasons for industrial electrical motor failures.

keeping motors at peak performance is becoming more complex, which is why facility operators should be able to conduct a motor failure root cause analysis.
how is motor speed regulated (lets say a pm dc motor)? is the voltage kept constant, and current increased/decreased, or is current kept same and voltage increased/decreased or both? what about torque and speed? will giving a motor too much voltage or current damage it? i'm trying to...

first of two parts industry estimates assert that 50 percent of all electricity usage and up to 70 percent of electricity usage in industrial plants is the direct effect of the energy used by motors.1 in the petroleum and chemical industry, average downtime costs $87,000 per hour.2 given that the initial cost of a 60-horsepower motor, for example, is less than $6,000, the reliability of motors is much more critical than the initial cost.
the reasons for electrical motor failure can range from the commonplace to the bizarre. we’ll take a look at some of the most common ones here.

electric motors used in the petrochemical industry are specified and designed for a minimum of 25 years of service life and at least 5 years of uninterrupted operation for [1] induction machines and synchronous [2] machines. original equipment manufacturer engineers are designing to meet these requirements using modern design software, the latest materials, improved manufacturing processes and better mechanical configurations and cooling techniques, the reality is that many of these motors will fail prematurely in the first years of operation. this paper discusses the most common contributing factors of medium and high voltage induction and synchronous motor failures in the petrochemical industry. these contributing factors include; design flaws, manufacturing defects, incorrect selection of motor enclosures, maintenance issues and motor protection. this paper will help end users understand the importance of the mechanisms that lead to critical motor failure and maintenance practices designed to help keep equipment in optimum condition. this paper does not discuss specific original equipment manufacturing issues; but instead focusses on general mechanisms related to early motor failures based on root cause analysis, experience history and end-user feedback.
the electric motors drive the world. regular maintenance, diagnostics, and timely troubleshooting prolong their lifespan.

there are a number of reasons for electric motor failure. these failures can lead to costly downtime and production interruptions.
a broad comparative study of the causes of electric motor failure is difficult to accomplish. motor manufacturers are involved in failure studies, as such, but only as far as is appropriate to satisfy warranty requirements. once the warranty period has passed the motor manufacturer almost never is advised of the cause of failure and, as a result, an attempt by the manufacturer to continue a failure study beyond the warranty period would be extremely difficult and costly.
electric motors are found everywhere in modern industry. they can be used to drive pumps, fans, conveyors, or crushers. motors are often critical parts of operations, and in the event of a malfunction or failure, an entire production line can come to a halt, leading to enormous costs related to both lost production and damaged […]
most problems with single-phase motors involve the centrifugal switch, thermal switch, or capacitor(s). if the problem is in the centrifugal switch, thermal switch, or capacitor, the motor is usually serviced and repaired. however, if the motor is more than 10 years old and less than 1 hp, the motor is usually replaced. if the motor is less than 1/8 hp, it is almost always replaced.
the average lifespan of an electric motor is approximately 40.000 hours. whether it will hit that mark depends on several factors such as pollution, overload, resistance, heat, and vibration.
