Electric Motors Failure: Causes and maintenance

Electric Motors Failure: Causes and maintenance

What are electric motors?

Electric motors are used in almost every industry; we cannot picture life without them. It is used in many appliances, such as electric vehicles, machines, and power equipment. Looking around will reveal that electric motor power every device and machine in our homes and offices. Electric motors may convert electrical energy into mechanical energy. Electric motors, powered by electricity, may rotate and revolve any object visible to the human eye. Because they are so energy-efficient and practical in every part of life, electric motors are a great option. They provide a less expensive alternative compared to other gadgets. The electric motor size you need will depend on your various activities. If you manage a small business, a little electric motor will be adequate for you. Whereas, if you want to expand your business operations, you must select a large electric motor that operates swiftly. It is necessary to purchase a new electric motor to avoid frequent breakdowns.


Electric motors failures

If any of your tools or machines have an electric motor, you should be aware of what goes wrong and take precautions to avoid it happening again. And the best method to deal with a problem is to identify its potential causes and address them. The lifespan of the electric motors is fixed, and after that time, it will start to tear up, so make sure to notice the changes. Furthermore, regular care is essential for them to survive a long time. Your electric motor will likely not last very long if you don’t perform the necessary maintenance. Electric motor failure can have a wide range of causes. Let’s find some of the significant and major causes of electric motor failure.


Reasons for electric motor failure



An excessive current flow within the motor windings, beyond the design current that the motor can carry effectively and safely, causes electrical overload or over-current. A low supply voltage may be to blame, forcing the engine to draw a more significant current to maintain torque. Shorted conductors or an excessive voltage supply may also be at blame.


Low resistance

Low resistance is likely the most frequent and challenging factor in motor failure. Low resistance is brought on by the windings’ insulation deteriorating from issues like overheating, corrosion, or physical harm. Inadequate isolation between the conductors or motor windings results in leakages and short circuits, ultimately leading to motor failure. Low resistance is caused by the breakdown of the insulation in the windings, which is further fuelled by corrosion, physical damage of any type, or overheating. Replacements should also be done immediately, if necessary, to prevent complete failure. Regular checks should be made for wear on the insulation to identify when it needs to be replaced before low resistance can lead to loss.



Mechanical issues

The most frequent reasons for electric motor failure are other mechanical and electrical problems. Keep an eye on your motor, and the instant you see any warning signals, repair it right once. Otherwise, the engine will fail shortly. For the health of your electric motor, it is best to choose and follow a regular maintenance approach. Additionally, get routine motor checks performed because doing so will allow you to keep tabs on the health of your electric motor and prevent it from breaking down.


Electric motor maintenance

You must ensure that any machinery is maintained if you want it to endure longer. All the actions necessary to guarantee that the machinery operates effectively are considered maintenance. Both the machine’s internal and external parts must be taken care of as part of its maintenance.

  • Cleaning the machinery is the first step in the maintenance process that you would need to list down. After several hours of daily use, certain dust particles may inevitably become lodged in your machine. Such particles could cause rapid changes in the machine’s operation. For this reason, you should routinely clean the engine and its components.

The machine won’t operate if its components, especially the electric motor, are destroyed. The electric motor requires professional maintenance if you see outward signs of wear and strain. You would need to take the electric motor for maintenance to ensure that it operates effectively for extended periods.
