Induction motors are one of the most popular and common types of electric motor on the planet. These types of motors don’t have brushes or commutators and thus are simpler than other types of engines. The simpler the engine, with less moving parts the longer in general it will last. People love induction motors because they are fast, efficient and powerful. These motors work in industrial applications, compressors, newer diesel trains, dishwashers, fans, swimming pool pumps, and other types of pumps.
Usually induction motors run well at a given torque and stable speed. Some have started using them with a variable-frequency drive to increase their uses. These are great little engines that don’t have to worry about brushes that will wear out and can go very high speeds. The rotor can come in the form of a squirrel cage or packed into a cylinder as a heavy set of coils. The stator is an electro magnet that is place around the outside of the motor.
If something happens to your induction motor, you must troubleshoot and diagnose the problem. Always keep a safe work environment. Always follow safe procedures and wear proper safety equipment. Always maintain safe electrical safety precautions and watch what you are doing. Do not be reckless when dealing with electric motors.
The most common issues are motor overheating, unbalanced voltage, motor overload, lack or torque or low speed, excessive vibration, misaligned or unbalanced loads, low voltage or pump cavitation.
Most of these motors will have a long life span if you take care of them and do the basic maintenance required. Always check the environment that they are in. When the engines are running, they produce heat. Most of these engines need to cool to remove some of the heat. If they are in an environment that are dusty or dirty then the dust can further insulate the already hot motor. Motors in an environment that has a high temperature or other heat source, need to move somewhere else. Further heat from the environment or heat source may transfer to the motor and cause overheating.
