AC motors are highly flexible in many features including speed control VSD - Variable Speed Drives and have a much larger installed base compared to DC motors, some of the key advantages are:. The current trend for VSD is to add more features and programmable logic control PLC functionality, which are advantages for the experienced used, but require greater technical expertise during maintenance. In this type of motor, the rotation of the rotor is synchronized with the frequency of the supply current and the speed remains constant under varying loads, so is ideal for driving equipment at a constant speed and are used in high precision positioning devices like robots, instrumentation, machines and process control. Click here for an example Synchronous Motor from RS. This type of motor uses electromagnetic induction from the magnetic field of the stator winding to produce an electric current in the rotor and hence Torque.

Energy-efficient motors, which can be two to eight percent more efficient than standard motors, owe their premium performance capabilities to new technologies. Energy-efficient motors, which can be two to eight percent more efficient than standard motors, owe their premium performance capabilities to new technologies and design manufacturing improvements. Motors are found in a variety of industrial applications, powering everyday tools such as fans, blowers, and pumps. According to the U.

These energy efficient motors are based on new patented designs and are essentially permanent magnet based brushless DC motors with very low electronic component count. The new designs have been developed for low torque ripple and quiet operation. The new motors are attracting growing commercial interest worldwide.
Power Quality in Power Systems and Electrical Machines, Second Edition helps readers understand the causes and effects of power quality problems and provides techniques to mitigate these problems. Power quality is a measure of deviations in supply systems and their components, and affects all connected electrical and electronic equipment, including computers, TV monitors, and lighting. In this book analytical and measuring techniques are applied to power quality problems as they occur in central power stations and distributed generation such as alternative power systems.

Last updated: October 31, D o you ever hear people talking about using a sledgehammer to crack a nut? Using too much force where only a little would do is obviously a waste of energy —but it's something we all do, all the time, where electricity is concerned. Broadly speaking, voltage is the electrical equivalent of force and we often power electrical appliances and gadgets with far more volts than they actually need. Using an "electric sledgehammer" to crack an electrical nut wastes money as well as energy and can dramatically shorten the life of expensive equipment. If you're running something like a factory with lots of huge machines powered by electric motors , using too much voltage might be adding an unnecessary 10—20 percent to your electricity bill; multiply that across the whole of the industrial world and you get a big problem that's bad for the economy and bad for the planet. One solution is to use voltage optimization equipment also known as voltage correction, stabilization, or reduction , which constantly regulates your electricity supply so you get precisely the voltage you need. Let's take a closer look at how it works!
Efficient Electrical Machines
Power electronics is the engineering study of converting electrical power from one form to another. A lot of energy is wasted during this power conversion process due to low power conversion efficiency. It is estimated that the power wasted in desktop PCs sold in one year is equivalent to seventeen MW power plants! It is therefore very important to improve the efficiency of these power conversion systems. Research Showcase. Researchers at North Carolina State University have created a high voltage and high frequency silicon carbide SiC power switch that could cost much less than similarly rated SiC power switches. The findings could lead to early applications in the power industry, especially in power converters like medium voltage drives, solid state transformers and high voltage transmissions and circuit breakers.

By: Kendall Jones on February 22nd, For years, the Environmental Protection Agency EPA has been enacting stricter emissions standards for nonroad diesel engines like those used in construction. Using a progressive tiered approach to reduce emissions, with Tier 4 Final being the most recent, the EPA limits new diesel engines to near-zero levels for emissions of nitrogen oxides NOx and particulate matter PM.
Стратмор наклонился и, зачерпнув воды, смыл со своих рук частицы плоти Чатрукьяна. Его мечта о Цифровой крепости рухнула, и он полностью отдавал себе в этом отчет. Теперь у него осталась только Сьюзан.
- Я снова его запустила. Посмотрим, вернулся ли. Разумеется, на ее экране замигал значок, извещающий о возвращении Следопыта.
Такая архитектура стала популярной в те времена, когда церкви одновременно служили и крепостями, защищавшими от вторжения мавров, поскольку одну дверь легче забаррикадировать. Теперь у нее была другая функция: любой турист, входящий в собор, должен купить билет.
