A Brief about Traction Motors

Being an electric motor, the traction motor is used for the propulsion of vehicles like hydrogen or electric vehicles, locomotives, etc. Finding use in electrically powered rail vehicles, traction motors are also utilised in other electric vehicles such as elevators, conveyors, trolleybuses, roller coasters, etc. Even battery electric vehicles and vehicles with electrical transmission systems (electric hybrid vehicles, diesel-electric locomotives) use traction motors.

The oldest type of traction motor is a direct-current motor which contains series field windings. Today, there are several traction motor manufacturers in India offering various types of products, which makes it easier to find the right type of motor for your application. Here is some more information about traction motors:

What is a Traction Motor?

Traction motors generate power that helps in the rotation of the wheels of a train. These motors generate a turning force that transfers to the wheels with the help of driving gear unit and axle.

Mechanical Features

Here are two of the many mechanical features of a traction motor:

• A traction motor should be robust and should have the ability to withstand constant vibration.
• The traction motor’s weight should be low so as to increase the vehicle’s payload capacity.

Electrical Characteristics

Here are the main electrical characteristics that a traction motor should show:

• Able to develop high starting torque: A traction motor should be able to develop high starting torque, particularly when the train has to accelerate at a rate that is reasonably high. 
• Able to withstand voltage fluctuations: Traction motors should have the capability to endure fluctuations in supply voltage without any undue impact on the performance. This is because when it comes to traction work, rapid voltage fluctuation because of heavy current inrush in the beginning is very common.
• Overload capacity: As a traction motor is subjected to arduous duty, it should be able to take the excessive load.
• Should have the capability to withstand temporary supply interruptions: A traction motor should be able to withstand temporary supply interruptions without an unwarranted current rush.

Given the numerous benefits traction motors provide, they find numerous applications in this day and age.

3 Things You Need to Keep in Mind Before Installing an Elevator

With multi-storey buildings being made all over the world, elevators have become the spine of every such structure. They provide structural support and ease the going up and coming down for people. Bangalore too is one of the fastest-growing economies in India, where the number of high-rise buildings is growing as well. However, when it comes to installing an elevator in a Bangalore high-rise, there are several factors that one must keep in mind before choosing one.

Safety

There are different grades and types of elevators available in the market. The first thing that you need to keep in mind while choosing an elevator is the safety of the people using it. With careful planning and proper installation, choosing the right type of elevator for your building is also important. For choosing the right type of lift, you will have to factor in the number of people who would use it and whether a particular type of elevator would be enough to bear the footfall of the building without causing long wait times.

Design

Though safety is always going to be the first priority for the builder, one should also keep the aesthetic aspect in mind. If you have built a new and modern office, you will have to check for the latest and trending designs, so that the lift does not take away the charm of your office or building. There are a lot of manufacturers that offer some of the best designs for elevators in Bangalore. So, you will have a lot of choice when it comes to choosing.

Capacity

This is also a very crucial factor that cannot be neglected. One should always install an elevator based on the footfall of the building. Every building has a different footfall, and this becomes a very critical point to keep in mind. This factor impacts a lot of things, from the design to the type of lift that will be best suited for your establishment.

Keep these 3 major aspects in mind while planning on installing a lift in any building for unhindered convenience and durability in the long term.

Reasons Why You Need an Air Curtain at Your Restaurant

As a restaurant owner, you may face many challenges, some of which are being able to keep your customers safe, being able to save energy, and keeping pests outside your premises. While there will be many other challenges for you to solve, the aforementioned are some that can easily be dealt with if you install an air curtain by Mitsubishi Electric India. An air curtain is placed over a door in order to create a powerful air seal over the opening.

Here are some of the top reasons why you should consider getting an air curtain by Mitsubishi Electric India installed at your restaurant:

Increases Customer Comfort

Keeping the customer happy is something that is imperative for any business. Maintaining a comfortable temperature inside the premises is a very important part of ensuring customer satisfaction and an air curtain can help you do that. The strong air-flow ensures that the warm or cool air inside remains inside. At the same time, the temperature is not affected by the outside weather.

Reduces Energy Costs

Keeping the door open is a proven way of attracting customers, but the open door can also lead to the hot or cold air outside getting in. This makes it very difficult for the restaurant’s air conditioning system to maintain the temperature it is supposed to. This, in turn, leads to the system overworking and generating high electricity bills. An air curtain, on the other hand, creates an invisible barrier, preventing the inflow and outflow of air, which protects the temperature inside. This means less wear and tear for your heating or cooling system and lesser electricity costs.

Promotes a Clean Environment

Air curtains restrict flying insects and other pollutants like traffic fumes, pollen, and dust from getting inside the restaurant. Creating an effective seal by re-circulating the facility air across a doorway, they make it harder for the outside air and pollutants to penetrate the air curtain.

Reduces Strain on Existing Heating or Cooling Systems

As mentioned before, with an air curtain, there is less stress on your heating or cooling system, which helps it last longer. Less usage of the air conditioning system also helps increase the lifespan and functionality of the same.

Choose from the range of air curtains by Mitsubishi Electric India and help your restaurant grow!

The Different Types of Elevators

Elevators form an integral part of our lives. In our society, which is replete with sky-high buildings, elevators are not only symbolic of luxury but an absolute necessity. Nowadays, there are various types of elevators available in the market, with each of them designed to suit a particular requirement.

Elevators can broadly be classified into two categories, which are mentioned below-

Traction Elevators

Traction elevators are the most commonly used and highly reliable elevators, in which the car is raised and lowered by steel ropes or belts on a pulley system. In comparison to other elevators, they use lesser energy and ride smoother. They are primarily designed to serve mid-to high-rise buildings and are driven by alternating current (AC) or direct current (DC) electric motors. They are further classified into three types-

• Geared Traction Elevators: These use a large-sized motor with a reducer and gears.
• Gearless Traction Elevators: These use permanent magnets for their operations.
• Machine-Room-Less (MRL) Traction Elevators: These elevators do not have a dedicated machine room above the elevator shaft.

Hydraulic Elevators

Hydraulic elevators are highly efficient elevators that are powered by a hydraulic jack, which are fluid-driven pistons travelling inside a cylinder. These elevators use the compression of fluids to generate movement. The sole objective of using hydraulic elevators is to transport heavy industrial loads such as machinery and other equipment. These reliable elevators are quicker and less expensive to install and occupy much less space in a building. They can further be divided into the following types-

• Holed Hydraulic Elevators: In holed hydraulic elevators, the hydraulic cylinders are placed inside a drilled hole.
• Hydraulic Elevators devoid of holes: This type of elevator doesn’t make use of drilled holes.
• Roped Hydraulic Elevators: Roped hydraulic elevators use cables and a piston attached to a sheave for transporting the load.
• Machine Room-Less (MRL) Hydraulic Elevators: In these types of elevators, the hydraulic lift mechanisms are located in the hoist-way instead of a separate machine room.

Further, with the advancements in technology, the costs involved in the manufacture of elevators have reduced considerably, making them quite affordable. Thus, you can install them easily without worrying much about your budget.

Circuit Breakers and Fuses: Definition, Working, and Advantages

Circuit breakers and fuses are used to prevent a high amount of current from overloading a circuit and to avoid the occurrence of an electric fire. They also intervene at the time of a ground fault or short circuit that can harm your electronic appliances. Read on to know more about the working and advantages of circuit breakers and fuses:

Understanding the working of circuit breakers and fuses

Fuses are constructed with a piece of metal. The metal melts when too much power passes through a fuse. These devices are the best option for over-current protection. On the other hand, circuit breakers contain moving and fixed contacts. These contacts touch each other and carry the current when the circuit is closed under regular conditions.

At the time of regular operating conditions, the circuit breaker’s arms can be closed or opened for maintenance and switching of the system. When a fault occurs in any section of the system, the trip coils becomes energized and the moving contacts move apart from one another because of a certain mechanism and in turn open the circuit.

Advantages of circuit breakers

Circuit breakers are circuit protection devices. There are many types of circuit breakers in the market, such as air circuit breakers, miniature circuit breakers, moulded case circuit breakers, earth leakage circuit breakers, etc.

• There are many advantages of using circuit breakers, such as:
• They are reliable circuit protection devices.
• They are sensitive in nature and respond very quickly.
• These devices can be reset.

Advantages of fuses

Fuses are protection devices against short circuits. They are used in both high and low voltage circuits that have a capacity ranging from moderate to high. Here is a list of advantages a fuse offers:

• It is the cheapest type of protection that can be used in an electrical circuit.
• They have a simple operation.
• They require zero maintenance.

These protection devices are extremely useful in electric circuits and can help you avoid an electrical fire.

Benefits of an Elevator in a Commercial Building

Many establishments such as big offices, hospitals, and shopping malls out there contain multiple floors. Because of this very reason, elevators have become a prerequisite for them. The elevators that you typically find in a commercial building are different from the ones you will find in a residential space as they have different designs.
Installing elevators in a commercial building with several floors offers numerous benefits, take a look:

1. Increases Productivity

A workplace is always buzzing with activity; office employees are constantly working to meet deadlines. When an elevator is installed in a workplace, a lot of time gets saved and the employees of an organisation get to be more productive and can save the energy they would have spent climbing stairs to reach different departments.

2. Helps in Moving Heavy Loads

An elevator is highly beneficial in a building where the shifting of heavy objects takes place between different floors. Using elevators to move heavy loads increases the efficiency of people working in the building and also saves a lot of time in day-to-day tasks. It also saves people working in the building from any potential injury or health risk.

3. Increases Mobility

An elevator helps increase mobility in a commercial building. For instance, an establishment where elevators find immense usage are hospitals. Right from moving patients on wheelchairs and stretchers to helping people who are not able to physically use the stairs, elevators offer numerous benefits in such a setting.

There are many elevator manufacturers in India that offer elevators according to the function needed in that building. For instance, the elevator of a hospital is designed for carrying the weight for plenty of people and with wider doors.

4. Does Not Take Up Space

Elevators only need a shaft to move up and down. Staircases, on the other hand, take a lot of space. You will have more room because of the space that is getting saved due to the elevator and can use it for something else.

So, you can see the several benefits of installing elevators in a commercial building. Specifically, places like airports, hospitals, terminals, depots, and malls should have elevators installed for the numerous benefits they offer.

Types of Air Conditioning Systems for Commercial Uses

To meet diverse needs, air conditioning systems come in various setups. Different air conditioning units come with different cooling and heating capabilities and are therefore used in varied settings like offices, factories, retail outlets, and other such commercial places. Following are the three major types of air conditioning systems that are used for commercial purposes:

Single Split Air Conditioning System

These types of air conditioning systems are the most inexpensive as compared to any other system. A single split system is commonly used in small commercial buildings as they are only capable of conditioning the air of an individual room. This makes them an ideal pick for shops, small offices, and server rooms. Mid-sized commercial spaces can also use more than one single split air conditioners so that they can serve a larger space.

Multi-Split Air Conditioning System

Multi-splits work in the same way as single splits do. But, depending on the model, one can link up to nine indoor units to a single outdoor unit. Such air conditioning systems are most commonly used in restaurants, offices, and departmental stores.

VRF Air Conditioning System

Medium to large commercial spaces like hotels, factories, and skyscrapers often employ VRF air conditioning systems. While VRF systems can easily meet the heating/cooling requirements of huge buildings, they are also quite efficient and easy to manage. Most businesses prefer this air conditioning system as it has lesser installation time which ensures the least disruption.

There are two types of VRF systems – heat pump and heat recovery. Heat pump VRF systems are used to provide either heating or cooling to a building which makes them a great pick for areas that are based on an open plan concept. On the other hand, heat recovery VRF systems can effectively provide heating and cooling simultaneously to different areas. This makes them an ideal pick for buildings that have a number of individual rooms.

These are the most common types of air conditioning systems that are used in commercial spaces. So, the next time you are planning to buy one, you can either search for commercial air conditioner systems online or visit your nearby electronic store.
