Plant and Process Engineering will be the backbone of any plant, chemical, or process engineer's library. This is a broad area in which engineers need to be familiar with a wide array of techniques, technologies and equipment. Its focus on providing a broad introduction to key systems make the book the first point of reference for engineers who are involved with designing, specifying, maintaining or working with plant, process and control technologies in many sectors, including manufacturing, chemical process, and energy.

Replacing your DC motors? Think AC
Motors and Generators
Electric motors are a primary means for furnishing motion on modern industrial machinery and equipment, but designers cannot bolt on the cheapest version that fits. Implemented properly, electric motors are a cost-effective and reliable method to create rotational motion, and they also can couple with gearboxes and other mechanisms to achieve varying levels and types of force. Motors that are not properly sized will be inefficient and can cause operational and maintenance problems. Designers are, at times, overwhelmed by the wide variety of motor manufacturers, styles and sizes available. Typical motors may be ac or dc, for fixed or variable speed, with steppers and servos as options for high-precision applications.
The war of the currents , sometimes called battle of the currents , was a series of events surrounding the introduction of competing electric power transmission systems in the late s and early s. It grew out of two lighting systems developed in the late s and early s; arc lamp street lighting running on high-voltage alternating current AC , and large-scale low-voltage direct current DC indoor incandescent lighting being marketed by Thomas Edison 's company. Using high voltage allowed an AC system to transmit power over longer distances from more efficient large central generating stations.
Considerations for keeping motors up and running with proper design and lubrication. Electric motors convert electrical energy to mechanical energy. Many types of electric motors for processing applications exist.SEE VIDEO BY TOPIC: How does an Induction Motor work ?
DC motors were first developed in the early 19th century and continue to be used today. The DC motor reigned alone in the factory for only 11 years. So, the question remains — why has the DC motor continued to be used from until today? An induction motor, on the other hand, always runs at full speed. If a speed other then this is desired, it must be achieved via belts and pulleys, hydraulic pumps and motors, or gear boxes and clutches. These devices provide for rotation at a speed something less or greater then the design speed, but adds mechanical complexity.
War of the currents
To understand how an alternating current ac induction motor works, it helps to look into the basics of magnetism and electromagnetic induction and how they impact the functions of ac induction motors. Magnetism refers to the force that attracts or repels two objects from each other. This action takes place because of a magnetic field that exists with the movement of electrically charged particles. Magnets, for instance, have a strong magnetic field which attracts certain ferrous materials to them such as nickel, steel, cobalt, and iron. Identical poles of two magnets repel, while opposite poles create an attraction. A magnetic field surrounds the space surrounding a magnet.
Bharat Bijlee is one of the leading Electrical Motor manufacturers in India. It offers a comprehensive range of highly reliable and energy efficient 3 Phase AC Electrical Rotating Machine from 0. This indicates that the electric motors consume more energy than any other application. With a steadily increasing installed base of electric motors, our nation has a tremendous opportunity to save energy. Minimum Energy Performance Standards MEPS was voluntary in the past but as per the recent mandate by the Indian government, the minimum efficiency of 3 phase squirrel cage induction motors that can be manufactured and sold in the country needs to be IE2 efficiency level conforming to IS standards.
Alternating-current AC and direct-current DC motors have traditionally served distinctly different applications due to their construction and inherent operating characteristics. In general, AC motors were smaller, less expensive, lighter and more rugged than DC motors. DC motors, on the other hand, operated better in variable-speed applications, particularly those requiring wide speed ranges, and provided more precise speed control. DC motors have been the workhorse of industry in many applications where variable-speed operation is needed.
2-3-2. Rotation Principle of Induction Motor
VFDs are used in applications ranging from small appliances to large compressors. Systems using VFDs can be more efficient than those using throttling control of fluid flow, such as in systems with pumps or fans. However, the global market penetration for all applications of VFDs is relatively small. Over the last four decades, power electronics technology has reduced VFD cost and size and has improved performance through advances in semiconductor switching devices, drive topologies, simulation and control techniques, and control hardware and software.
This chapter discusses power motors used at plants Fig. An introductory book to motors explains the principle of rotation of induction motor using Arago' disc see Fig. The rotor of general induction motors has the structure shown in Fig. If you disassemble the rotor, you will see that it is not a disc and that it is composed of a silicon steel plate and a cage-shaped aluminum part as shown in Fig. Such a rotor is called a squirrel-cage rotor.
