Fundamental of electrical machine

           ELECTRICAL MACHINE In Electrical engineering , electrical machine is generally refers to machines using electromagnetic force it means electrical machines needed electromagnetic induction to operate and work, such as electrical motor, generators, transformers etc.  Basically if we see rootly then electrical machine are basically electromagnetic energy converter. It changes electromagnetic energy in one form to another. For example. Generators produces Electricity by using mechanical induction and it converts it into electrical energy.  For optimised or practical operations of electrical machines, today's electrical machine are complemented by electronic control.        TYPES OF ELECTRICAL MACHINE On the basis of movement electrical machine can be categorized in following two types.  1-rotatonary electrical machine.  2-static electrical machine.  On the basis of supply used...

Electrical machines

         ELECTRICAL MACHINE Electrical machines are such devices or apparatus which converts energy in one form to another to make the task easy.  Such as transformers., motors, generators,    TYPES OF ELECTRICAL MACHINE electrical machines are various types but in the basis of supply use we can categories in following two types.  1-AC Machine 2-DCMachine From the above categorization the first one means actually machines are more utilized in this time, because of nature of generation supply is totally ac type, that's why ac machines are more familiar to all of us.  In beginning time first DC machines were arrived but due to it's high initial and operating costs, maintenance costs and poor efficiency in comparison to ac machines, ac machines won the race, which results we can see in our today life.  It will be said worthful that now we are totally surrounded and depended on machines.  Well, it was ...
