|1. General information about electrical machines|
The operation of electrical machines results from their incorporation into the process of energy conversion in the generation, transmission and consumption of electric power.
Thus, for example, in a power station the combustion heat of coal, natural gas, etc. is employed in boilers for steam generation. The energy flow of the steam drives the turbine which is coupled to a turbine generator that converts the flow energy into electric energy. The efficient transmission and distribution of electric energy is ensured through the high voltages generated by the transformers. Thereby, the high voltages are switched to consumer voltage and directed to a motor whose mechanical energy drives machines in industry, the home and traffic.
