Adjustable Speed Drives For Energy Saving Costs
Are you still searching for the most effective way so as to lessen your energy expenditures to your industrial setting? As a plant or store manager and even plant owner, perhaps, you realize that a large quantity of the energy on your facility is utilized to large power fanatics, heavy duty equipment, machinery, pumps and other energy supply equipment’s. Your facility perhaps utilizing a DC to power motors, and it’s expected that claimed motors are functioning in full speed despite the fact that the speed is just not neccessary. Unluckily, this brings a strain in the motor that decreases the life time and results in in wasting way more energy. Hence, what if you may redirect some of this energy in order to use in an alternative site in the plant? For this instance, variable speed drives can aid you a lot in saving your energy costs to your producing setting.
Variable speed drives make it more possible and have the abilities to be regenerative in feed. The regent drives essentially retrieve the energy towards supply system. In this way, the energy just isn't wasted in a technique of inertial heat loss or load loss. Using variable speed drives furthermore leads on to cutting down heat, which discharges the air conditioning in commercial setting, somewhat in production areas additionally reduces the carbon dioxide emissions. Imagine by just adding a flexible type of variable speed drive to power motors in working area in your cooler facility, this may decrease the energy expenses in supplementary means and as well make the working area be more comfy as well as manageable for workers.
The variable speed drives not just lessens the energy price of your commercial settings yet also lessens the overall fees in production. The operational cost consistently consists of the energy cost in manufacturing. Once the commercial producing minimizes the costs in energy and raises the excellence of the product, the commercial manufacturing is actually lessening the entire expenses in generation. The saving costs may be used by the firm in raisingthe profits and the quantity of the merchandise, upgrade all industrial facility, step up the marketing efforts in addition to use as an benefits to your workers.
So how do variable speed drives work for your commercial facility? 1st, you need to communicate to a qualified engineer about the application necessities. Most of manufacturers always work with to their clients in order to determine the clients require as well as on how it need to work, even if you purchase through supplier. Variable speed drive may be modified if you've an older kind of power motor. This can assists you to avoid the costly job of replacing the old motor with a brand new one. Because variable speed drives control and operation is more upfront than another type of motor drive, the degree of the speed torque and loading are simpler to judge. This make the whole process of installation run smoothly in several type of application, thusly reduce the expenditures even if it takes numerous upgrading.
You must take into account that variable speed drives are energy saving equipment. The variable speed drives also present numerous advantages; hence you'll be saving time, cash and effort in various means as refining the general operation of your industry.

Variable Frequency Drivse and its Know-How
What is frequency drive? Variable-frequency drive is a device that helps in saving energy in terms of electronic is various kinds of machines and devices that operate with electrical energy. It works as a controller. Frequency drive actually controls the electrical energy, and this leads to control of AC motors with controlling or reducing rotational speed. Frequency drive known with different names such as AC drives, Inverter drives, adjustable frequency drives, etc. Nowadays, variable frequency drive is a very important aspect of manufacturing industries and different kinds of machines. It is widely used in cranes, hoists, elevators, pumps, etc. Frequency drive is really helpful in saving energy by maintaining frequency in electronic devices.
How Frequency drive works? I said earlier that frequency drive helps save energy and very useful in electronic devices. Now let me tell you that how frequency drives do this. Variable frequency drive uses IGBT in order to control or reduce power. IGBT works like a switch in electronic equipments that ultimately control the voltage or frequency of electronic equipment s output power. Are you still confused? Let me explain you how it functions? Generally, without frequency drive when induction motors draw many times when initially it comes in contact with heavy voltage at the time of starting device. At the time when the load of the device increases the torque drop and rise to pick a speed and then device reaches the full speed with acceleration where as during this process, current remains high. However, with the frequency drive the action is totally opposite. When the frequency drive is used in a motor and when it starts frequency drive asserts very low application voltage and frequency which lead to minimum inflow of current.
Benefits of frequency drive I have already mentioned that frequency drive or AC drive helps in saving energy. However, there are numbers of other benefits and putting forth few for your knowledge. Earlier motors used to be in need of softer required as AC drive controls the frequency and voltage softer starter is no longer required. Using a frequency drive means low maintenance and longer life of devices or electronic equipments. The maintaining and using AC motors also give you rid of choking valves and dampers. It also solves the water hammering problem as it asserts increment of speed gradually and steadily rather suddenly. There are few types of equipment that is not capable of tolerating over torque in such a situation frequency drive helps a lot as it allows to select different level of torque by the user itself.

تكنولوژي الكترونيك قدرت و درایوهای AC
تکنولوژی الکترونیک قدرت (Power Electronics) ، بهره وری و کیفیت فرایندهای صنعتی مدرن را بی وقفه بهبود میبخشد. امروزه با کمک همین تکنولوژی امکان استفاده از منابع انرژی غیرآلاینده بازیافتی (ReneWable Energy ) ، نظیر باد و فتو ولتائیک فراهم شده است. تخمین زده میشود که با استفاده از الکترونیک قدرت، حدود 15 تا 20 درصد امکان صرفه جوئی انرژی الکتریکی وجود دارد [1]. در واقع با کاهش بیوقفه قیمت ها در عرصه الکترونیک قدرت زمینه برای حضور آنها در کاربردهای صنعتی، حمل ونقل و حتی خانگی فراهم میگردد. نیروی محرک بيشتر پمپها و فن ها موتورهاي القائي هستند که در دور ثابت کار میکنند. ليكن در سالهاي اخير با پيشرفتهاي انجام گرفته در زمينه تكنولوژي الكترونيك قدرت ، استفاده از موتورهاي القائي قفس سنجابي همراه با كنترل كننده دور موتور (AC DRIVE يا اينورتر يا بطور ساده درايو) رو به گسترش است . درایوها دستگاههائی هستند که توان ورودی با ولتاژ و فرکانس ثابت را به توان خروجی با ولتاژ و فرکانس متغیر تبدیل میکنند. باید توجه کرد که دور یک موتور تابعی از فرکانس منبع تغذیه آن است. برای این منظور یک درایو نخست برق شبکه را به ولتاژ DC تبدیل کرده و سپس آنرا با استفاده از یک اینورتر مجددا به ولتاژ AC با فرکانس و ولتاژ متغیر تبدیل میکند. در شکل(1) قسمتهای اصلی یک درایو ولتاژ پائین نشان داده شده است. همانطور که مشاهده میکنید قسمت اینورتر متشکل از سوئیچهای قدرتی است که در سالهای اخیر تغییرات تکنولوژیک زیادی پیدا کرده اند. در واقع با معرفی سوئیچهای قدرتی چون IGBT با قیمتهای رو به کاهش، زمینه برای عرضه درایوهای با قیمت مناسب فراهم شد. در هر حال خاطر نشان میکنیم که شکل موج خروجی درایو ترکیبی از پالسهای DC با دامنه ثابت است. این موضوع موجب میشود که خود درایو منشا اختلالاتی در کار موتور شود. برای مثال کیفیت شکل موج خروجی درایو میتواند سبب اتلاف حرارتی اضافی ناشی از مولفه های هارمونیکی فرکانس بالا در موتور شده و یا موجب نوسانات گشتاور Torque Pulsation در موتور گردد. با این حال درایوهای امروزی بدلیل استفاده از سوئیچهای قدرت سریع این نوع مشکلات را عملا حذف کرده اند.
Variable Speed Drives (VSDs) in few words
A variable frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor. A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives. Since the voltage is varied along with frequency, these are sometimes also called VVVF (variable voltage variable frequency) drives.
For reason of energy savings, reduction of operating costs, reduction of machine down time, maximizing productivity and the ability to provide adjustable speed control with standard squirrel cage induction motors, variable speed drives are becoming the essential components in every modern automation system.
The acceleration , deceleration, high speed, low speed, foreword, reverse operation, preset speed, jogging can be programmed by the VSD, it has breaking system that uses DC injection, it’s breaking mechanism use the following principal. First is disconnect the all three phases to motor. Then its supplied 230V DC to two phases. Which operate permanent magnetic field, which hold the motor preventing motor. The speed controlling is done in VSD by changing the value V/F ( Voltage/ Frequency) in the supply to motor
An electric motor uses electrical energy to produce mechanical energy. The reverse process, that of using mechanical energy to produce electrical energy, is accomplished by a generator or dynamo. Traction motors used on locomotives often perform both tasks if the locomotive is equipped with dynamic brakes. Electric motors are found in household appliances such as fans, refrigerators, washing machines, pool pumps, floor vacuums, and fan-forced ovens. Motors operated by small batteries, while technically electric, are often called battery motors.
Most electric motors work by electromagnetism, but motors based on other electromechanical phenomena, such as electrostatic forces and the piezoelectric effect and thermal motors, also exist. The fundamental principle upon which electromagnetic motors are based is that there is a mechanical force on any current-carrying wire contained within a magnetic field. The force is described by the Lorentz force law and is perpendicular to both the wire and the magnetic field. Most magnetic motors are rotary, but linear motors also exist. In a rotary motor, the rotating part (usually on the inside) is called the rotor, and the stationary part is called the stator. The rotor rotates because the wires and magnetic field are arranged so that a torque is developed about the rotor's axis. The motor contains electromagnets that are wound on a frame. Though this frame is often called the armature, that term is often erroneously applied. Correctly, the armature is that part of the motor across which the input voltage is supplied. Depending upon the design of the machine, either the rotor or the stator can serve as the armature.
Low Voltage AC Drives
AC drives are used to control the speed and torque of a standard induction motor, the workhorse of the industry.
AC drive technology extends the motor speed range from zero to high above the rated speed, increasing the productivity of the driven process. When a low capacity is enough, the drive reduces the machine speed and saves energy. VTdrive can offer the industrial drives which are available both as complete AC drives and as modules to meet the requirements of the users, OEMs and system integrators. These drives are highly flexible AC drives that can be configured to meet the precise needs of industrial applications, and hence order-based configuration is an integral part of the offering.
Industrial drives
VTdrive can offer the industrial drives which are designed for industrial applications, and especially for applications in process industries such as the pulp & paper, metals, mining, cement, power, chemical, and oil & gas.

Compressed air is not only one of the most important utilities in industry today, but one of the largest consumers of energy. Generating compressed air can account for up to 10% of total industry energy consumption, increasing up to 40% in certain applications. Any savings that can be made in compressed air systems can therefore have a significant impact on costs and on the environment. In view of this Atlas Copco has been continuously innovating in energy efficient compressed air solutions for many years.
Our commitment to reduce the carbon footprint of our equipment at every stage of a compressors' lifetime, from cradle to grave has drastically reduced our carbon emissions. As a result of this, today more than 99% of the carbon footprint of a compressor is now in its operation, with less than 1% generated from its design, manufacture and distribution.
Energy is the most important factor in the total cost of ownership of Atlas Copco products. Through continuous innovations such as our Variable Speed Drive technology, Atlas Copco sees it as a duty to get these costs down. As energy consumption typically represents over 80% of a compressor's lifecycle cost, energy savings in compressed air systems will have a significant impact towards preserving not only the environment but also your bottom line.
Our latest innovation can be found in our Carbon Zero range of compressors, where our customers can recover up to 100% of the input energy, by converting the input electrical energy into heat through our unique built-in energy recovery system. Stephan Kuhn, President of Atlas Copco's Compressor Technique business area says: "Today our customers face stringent targets to reduce carbon dioxide emissions. With the Carbon Zero compressor, customers can get compressed air virtually for free, which has significant impact towards preserving the environment and also on their bottom line."
Our passion for efficiency is not limited to industrial applications and equipment; our FuelXpert™ option intelligently regulates the engine speed and air intake of our portable diesel-driven compressors, optimizing fuel consumption. This results in direct savings of 10%.

Atlas Copco is committed to sustainable productivity
By Michael Sagermann
What does it mean to be committed to sustainable productivity? At Atlas Copco productivity is at the forefront of all our business activities; it means helping our customers get more out of every investment.
One of the most important drivers affecting productivity and subsequently lifecycle cost is energy efficiency. Typically in terms of our products lifecycle cost, energy represents up to 80% of the total investment, especially considering air compressors. While compressed air systems on average account for about 10% of industrial electricity consumption, it can be as high as 40% of a plant's electricity bill. For these reasons, Atlas Copco has been innovating for energy-efficient solutions for many years. This has resulted in some of the most innovative and efficient air and power systems on the market today.
There are many ways to increase efficiency and productivity. Directly through technological innovations or indirectly through greater reliability, longer maintenance intervals, eliminating the risk of product contamination and recalls. Our history of energy efficient innovations reaffirms our commitment to sustainable productivity.
Atlas Copco was the first to offer a certified 'net zero energy consumption' air compressor - the Carbon Zero range. The built-in energy recovery systems in the ZR range are the first in the world to be TÜV-certified for 'net zero energy consumption', where it had been proven and independently verified that 100% of the electrical power input could be recovered in the form of hot water. This is most beneficial to those industries with a constant need for hot water and steam in their processes.
We were also the first manufacturer to offer TÜV-certified 100% oil-free compressed air, setting a new industry standard for air purity ISO 8573-1 Class 0, which safeguards industries processes and end products. Industries who risk contaminating their products with oil may expose themselves to product recalls, legal action and the negative consequence these have on a company's reputation and brand equity. 100% oil-free air also minimizes your maintenance cost and frequency as you no longer have to change oil filters.
Atlas Copco was also the first manufacture to offer air compressors powered with our innovative VSD (Variable Speed Drive) technology. Through varying the speed of the drive motor, the compressor output closely mirrors the air consumption over a wide range, without load-unload switching, meaning that fluctuating demand no longer means high energy costs. This results in an average energy saving of at least 35% and a reduction in overall lifecycle cost by 22%.
Our FuelXpert™ technology intelligently regulates the engine speed and air intake of our portable diesel-driven compressors, optimizing fuel consumption. This results in direct savings of 10%. It has been estimated that is all Atlas Copco's portable compressors were fitted with the FuelXpert™ option we would save more than 150 million liters of fuel per year.
Indirectly, regular maintenance not only keeps your production process running at its peak efficiency but can also significantly reduce your operating costs. Maintenance typically accounts for only 10% of the total lifecycle cost of an air compressor, whereas electricity alone can account for as much as 80%. A well planned maintenance program with regular servicing can significantly improve the energy efficiency of your compressed air or power system and drive down your operating costs.
Despite the exceptional reliability of Atlas Copco systems, the replacement of filters or lubricants, the periodic check of moving components and even a planned major overhaul are vital to ensure reliable efficient performance. Reactive interventions cannot avoid the cost of production losses caused by a breakdown which are often much more costly as you may have to replace, rather than repair major components. Atlas Copco's service plans are not only the lowest cost and most reliable solution in the long run but are very easy to budget for; as there are no surprises.
Atlas Copco aftermarket services are not limited to maintenance. True peace of mind only comes about in the knowledge that your compressed air or power system is optimally sized, installed, maintained and operating efficiently. Atlas Copco's air audits, remote monitoring and energy optimization solutions perfectly compliment our service plans.
For the fifth consecutive year, Atlas Copco has been named one the World's most sustainable companies. The Global 100 list of the world most sustainable corporations was announced at the World Economic Forum in Davos, Switzerland.
