ELECTRIC MACHINES

An electrical machine is a device capable of transforming any form of energy into electrical energy or vice versa, and machines that transform electricity into the same form of energy but with a different presentation more convenient for transport or use are also included in this definition. . They are classified into three large groups: generators, motors and transformers. Generators transform mechanical energy into electrical energy, while motors transform electrical energy into mechanical energy by turning a shaft. The motor can be classified as DC motor or AC motor. Transformers and converters preserve the form of the energy but transform its characteristics. An electrical machine has a magnetic circuit and two electrical circuits; Normally, one of the electrical circuits is called excitation, because when it is crossed by an electric current, it produces the necessary ampere-turns to create the flux established in the whole of the machine. From a mechanical vision, electrical mac...
