What is an Electrical Machines ?
An electrical machine is a device which converts mechanical energy into electrical energy or vice versa. Electric Machines also include transformers, which do conversion between "mechanical and electrical form but they convert AC current from one voltage level to another voltage level".
Electric machines were developed beginning in the mid 19th century.E machines, in the form of generators, produce all electric power on Earth, and in the form of electric motors consume approximately 60-70% of all electric power produced. Developing more efficient electric machine technology is crucial effort for conservation andgreen energy.
