Electrical motor are devices that turn the mechanical power to electrical power or the other way, it also changes the alternating current from one level to other level. It can additional be divided into three parts i.e. A motor, generator and transformer. There are discrete type of these electrical machines which are employed in industrial, power stations, domestic and commercial appliances.
A generator is a dynamic electrical power motor which converts the mechanical power to electrical energy. It can be additional classified as two types: an Ac generator and a Dc generator depending on the type of electricity being generated. Motor is the second type electrical motor which converts the electrical power to yield mechanical energy. It is also additional classified as Ac motor and Dc motor. The Ac motor is one which has an Ac electrical power as its input ad converts it to mechanical energy. In a Dc motor the Dc electrical input gets converted to mechanical energy. The third type of electrical motor is the transformer. It converts the alternating current from one lever to a higher or lower level without changing its frequency. A transformer basically works on the principle of mutual induction development the power and frequency remain constant.
Electric Motors And Drives Fundamentals Types And Applications
The modern studies and advances in power electronics and microprocessors have led the focus on electrical machines with respect to its application in commercial drives. The major study areas comprise power electronics and control and electric traction. A lot of work has gone in designing discrete types of these machines, their operations, application and ways of determining their parameters. New ways of protecting these machines against any overloads or mechanical faults are also being done to ensure a exquisite application, maintenance and its protection for a long life.
There are many other study projects going on to get advances in the building organize and material used in these machines. Things like advances in magnetic material and its impact on electricity, advances in brush less permanent magnet Dc motors, synthetic intelligence based machines and drives, advances in powder metallurgy soft magnetic composite material etc are taking these machines to new heights meeting all demands. Today a wide range of electric motor products meet all the diversified demands and needs of energy, industry, infrastructure and domestic needs.
