How to Reduce Down-Time with Motor Repairing


One of the greatest hassles in any industry is unexpected machinery breakdowns. Downtime caused by faulty or outdated machinery can be particularly expensive for a business, as the whole operation is put on hold during the Motor Repairing process. It is vital, therefore, to find a repairs service that offers prompt completion of repair jobs, as well as other beneficial services such as free pick up and delivery and extended working hours for emergencies.

It is essential to take broken down motors to a professional service, whether your business is large or small. It is possible to learn DIY techniques onlinen to fix small problems with your machinery, but for major breakdowns, it is more economical to take your motor to a professional who can fix the system quickly and efficiently. It is also important to regularly service and perform maintenance checks on the machinery to prevent major disruptions to the operation of your business.

To prevent machinery breakdowns, always keep the essential tools close by to keep your motor at maximum working order. In the event of a breakdown, go to a specialist who will have all the necessary parts and tools on hand to fix your machinery in a day or two rather than in a week.

Choose a motor repairing service that has a good reputation for quality, enduring repairs and a quick turnaround. Remember that although you are trying to reduce down time in your factory or plant with efficient services, it is also vitally important that the work done is of a high quality and will counteract further disruptions.

How Do Electric Motors Help The Environment?


There are a lot of words and phrases tossed around when the topic of electric motors comes up. One of these phrases is ‘environmentally friendly’, but in what ways do these motors really help the environment?

They are becoming increasingly used in windmills, which, in turn, are used to generate wind-powered ‘clean’ electricity. Electric motors are used to rotate the windmill heads 360* so that the blades are always placed within the wind’s current, allowing for increased opportunities to collect energy.

Electric motors are also frequently used in gate-operated dams. These kinds of dams require the motors to open and close the gates, allowing water to flow through or be blocked when needed. Gate-operated dams are quite often used in the production of hydro electricity, another clean energy source.

The use of electric engines in cars and other vehicles helps to reduce the tailpipe emissions and overall carbon footprint that gas and petrol powered cars leave on the environment. Cars running solely on electricity do not release any pollution or tailpipe emissions, and even hybrid cars’ emissions are greatly reduced. Electric motors are also much more energy efficient than either gas or petrol engines – 90% of the energy produced actually makes it to the road, compared to the 15-20% that makes it in a gas or petrol model.

While the construction of electric motors, including the various batteries that are used to run them, quite often uses energy produced by coal (which is very environmentally damaging), this does not necessarily have to be the case. Motors and batteries created using ‘clean’ energy, such as wind-, hydro-, solar- and nuclear-power, are just as environmentally sustainable as the motors and batteries themselves.

What You cannot Ignore While Repairing Electric Motor

Electric motors are very common and can be seen in almost all equipments which are powered by motors. Be it a vehicle, airplane, pool pump in a swimming pool or a lathe in a woodshop, uses of motor is very common. Electric motors have become an integral part of business and factories. Hence, users have to be attentive about motors’ working. Time may come when you will find some part of motor is not working.

In such case when you are seeking electric motor repairs, make sure that you get qualified mechanics that are specialized in repairing electric motors. Electric motors are very complex and require skilled labors. If the motor you have is small, you can call technicians. However, if you have large motors and you really need electric motor repairs, contact companies which have motor repair divisions.

These companies provide mechanics and technicians who are well skilled in repairing both A/C as well as D/C motors. They are not just skilled but are also equipped with advance tools. Besides, you must also check if the company you are about to contact provides certified warranty repair facility in case, your motor in under warranty period. It is better to be on the safe side no matter if you have got small motor or a large motor. A small mishandling can lead to serious damage. No doubt, you have to be very careful while you are seeking electric motor repairs.

Why Three Phase Motors Are More Popular?


Before three phase motors were launched single phase motors were ruling the market. Three phase motors being compact, economical and more efficient soon replaced single phase motors having same voltage class and rating. Hence, single phase AC motors are rarely manufactured.

Three phase motors are designed very simple, yet have high starting torque and extraordinary efficiency. These motors distribute electric power in the form of 3-phase AC. It uses three conductors that help it to provide 173% more power compared to the two conductors of a single-phase system. Three-phase technique empowers heavy duty industrial equipments to perform more efficiently and effortlessly. Plus point with these three phase power that it can be transmitted over long distances using smaller conductor size.

These motors have large numbers of versatile applications in the industries. Three phase pumps, blowers, fans, compressors, conveyor drives, farm machinery, saws, machine tools and similar other types of three phase motor-driven devices. There are huge benefits of using a three phase electric motors if compared with a single phase electric motor. These motors save a lot of energy and helps equipments operate smoothly. One of the most common examples is the large air conditioning equipment units above 2.5 tons (8.8 kW) cooling capacity that uses three phase motors for saving money and better performance. Besides all, they require very less maintenance and are perfect for tool where dust is prevalent. They also last very long. If used under normal operating conditions, these motors last for at least ten years. Perhaps, these are the reasons that make three phase motors popular for industrial use.

Why You Should Choose an Experienced Mechanic for Electric Motor Repairs

An experienced mechanic can give your machinery all the specialised care it needs. It is vital to choose a mechanic for electric motor repairs who is familiar with all the different models and types of machinery to ensure that you get the most comprehensive service possible. Many manufacturers and distributors offer an additional maintenance and rewinding service which can prove to be very useful if your motor fails when it is needed most.

For many mechanics, rewinding electric motors has become second nature after years of experience in the industry. This means that by choosing an experienced mechanic you can be sure that your machinery will be diagnosed and fixed in the quickest time possible. An experienced mechanic will also be able to customise the service to your requirements, fine tuning the machine to work exactly as you need it to.

An experienced mechanic will be able to do electric motor repairs of all sizes, allowing you to ensure that your whole plant or factory is kept at optimum working pace at all times. By going to a well established repairs firm you can also be sure that the mechanic will have access to all the necessary tools and equipment, again reducing down time for your machinery and workplace.

Whether you need a large turbine generator or a small battery operated device fixed, it always pays to go to an experienced mechanic rather than a shoddy tradesman or an enthusiastic DIYer. For the best results with your electric motor repair, you should call a mechanic who has experience working with your particular machinery.

What are Electric Motors?


The 'AC' in AC motors stands for alternating current and indicates that these machines use an alternating current to provide power. An alternating current means that the electrons traveling along the conductor switch direction regularly, so that they flow first forwards and then backwards. AC electricity was first invented by Nikolas Teklas in the 1880s. AC electric motors can retain energy more efficiently than DC machines and they are also better able to transfer different amounts of power.

AC electric motors consist of two main parts: the external stator and the internal rotor. The stator is responsible for producing a rotating magnetic field which in turn produces the torque received by the rotor. There are two different categories of AC machines, the induction and the synchronous. Induction electric motors use an induced current to produce the magnetic field and will always runt at a slightly slower or faster speed than the supply frequency. Conversely, synchronous machines do not rely on an induced current and are able to run at exactly the same speed as the supply frequency.

Most AC machines use squirrel cage rotors, named for their resemblance to the exercise toy for rodents. These rotors have two ring shaped windings at either end with bars running along the length of the rotor. The squirrel cage rotors used in AC electric motors generally act as transformers, acting to bring the rotor into synchronisation with the stator's field. As the mechanical load on the machine increases, the rotor also increases the power used.

AC electric motors are used for a variety of applications, from washing machines and dishwashers to heavy industry.
