Summary
Fractionation of electrical machines, materials used in electrical machines, fundamental laws for electrical machines. Fundamental principles are studied for transformers, inductions and synchronous machines, DC machines and commutator machines. Education deals also with principles of reluctance, stepping and linear motors. Laboratory education is concentred on measuring on these machines.
