Mechatronics Engineering
A formal definition of mechatronics is “the synergic integration of mechanics, mechanical engineering, electronics, computer technology and IT to produce enhanced products and systems.
Mechatronics is a vast subject which has deep roots in the fields of mechanical, electronic, computer and control engineering. Mechatronics is exceptionally useful in design engineering to create new products. Actually it is a combination of mechanics, computing, controlling etc. This combination made possible the invention of more versatile systems.
A robot is the typical example for a mechatronic system. It includes all the aspects of above said subjects. The collaboration of mechatronic molecules gives rise to new different formats of designs. Mechatronic is such an advanced field of technology which makes possible new creations with the help of almost all the major branches in technical field. Hybrid systems important to mechatronics include production drives, synergy drives, planetary exploration rovers, automotive subsystems, auto focus cameras, hard drives and CD players.
It has applications on automation and robotics, servo mechanics, sensing and control systems, automotive engineering, biomedical engineering, computer aided design, manufacturing systems etc. So this topic is much relevant to discuss about.
Electrical equipment is an appliance powered by electricity. This includes an enclosure, several electrical components, power switch etc. A machine which is the part of an electrical distribution system can be put under the category of electrical equipment. The components in this include switch board, distribution board, circuit breakers, energy meters, transformers etc
Let’s have a look at some significant electrical equipment. Electrical switch board is a major appliance. It directs electricity from one form to another. These switch boards contain large number of panels and each of it contains switches to redirect electricity. Actually the control of electricity to this switch board is carried out by electrical generators. As the power law defines the amount of power entering and leaving the switch must be equal. So generators make this stable. While going to the technical side of switch boards, it contains bus bars inside the case to isolate the switch board from the connections before it gets opened.
Distribution board is key electrical equipment. The main function of a distribution board is to divide the electric power feed into subsidiary circuits. It provides a safety breaker and fuse for each circuit in a common enclosure and hence the distribution board is sometimes called as power breaker.
An unavoidable part in electrical equipment section is circuit breakers. Basically it is an electric switch. It is designed to protect a device from over current or short circuit. It detects the fault if any and stops the flow of current to it. It incorporates manual as well as automatic control for switching operations. The latter control employs relays and operates only under fault conditions.
Its known to every one, transformer holds the top slot in the priority list. It’s a static piece of apparatus by means of which electric power from one circuit is transformed into electrical power of the same frequency in another circuit. It can raise and lower the voltage according to the need with the increase or decrease in current. The physical basis of a transformer is mutual induction and it works under the principle of Faraday’s laws of electromagnetic induction.
The above explained are some of the main electrical equipments which hold the key place in this section.
ELECTRICAL ENGINEERING
It is commonly known as Electrical & Electronics engineering. Electrical engineering has as much relevance as electricity has in our life. So it is considered as one of the major and basic branches in engineering field. We can’t even think of an earth with out electricity.
At first this branch dealt with electricity, electronics and electromagnetism, now power electronics, power systems, digital signal processing, control systems are all handled by an electrical engineer. The major advancement in this field was emerged by late 19th centaury. By 17th centaury the work on electricity got started. It includes the famous works done by George Ohm on the relationship between current and potential difference, Michael Faraday’s Electromagnetic induction, James Clerk Maxwell’s theory on electricity and electromagnetism. These all made the advancement of an electric era so fast.
Major and noticeable inventions in this field are Cathode Ray Oscilloscope by Karl Ferdinand Baum, Diode by John Fleming, Triode by Robert Von Lieben and Lee Deforest, Albert Hull’s Magnetron which eventually lead to the development of Microwave oven by Percy Spencer. These inventions made our life as wonderful as we wish. We know how well these all take parts in our life.
In the field of education, an electrical engineer covers Maths, Physics, computer science, specific topics in electrical engineering. They should have detailed knowledge in Electrical machines, signal processing, power systems, power electronics, and control systems
An electrical engineer has to work in the development of wide range of technologies. They use to design, test and supervise all electric systems. They are destined to work in electric power stations, telecommunication systems, and satellite communications, in the fields of power generation, transmission and distribution. It includes work on transformers, motors, alternators, generators etc.
Electrical engineer has a key role in the field of space flight. Control system is a major topic in electrical engineering; this plays an exceptionally strong role in space flight. Electronics is the sub discipline of electrical branch. It involves the testing of electric circuits, properties of resistors, capacitors, diodes etc. It deals with the study of radar, commercial circuits, microprocessors and its applications on different fields.
Digital signal processing is an unavoidable section in electrical engineering. It deals with the analysis and manipulation of signals. Another markable feature is in the field of computer technology. This involves the designing of computer and computer systems.
In short, in every walk of our life we can feel the importance of electricity and hence electrical engineering.
