... is the magnitude of the fundamental component of the line currents flowing through the stator windings [8]. When the output current increases, currents flowing through the stator windings and the diode rectifier increase. Accordingly, when the alternator speed increases from 1000 to 3000 r/min, powe ...

... For example, when a magnetic field is applied to a normal magnetic material like Iron, the material's magnetization increases smoothly as the atomic spins come into alignment with the field. But in 2004, researchers in Japan found that in spin ice this relationship was more complex. Instead of incre ...

Electric machine

The academic study of electric machines is the universal study of electric motors and electric generators. By the classic definition, electric machine is synonymous with electric motor or electric generator, all of which are electromechanical energy converters: converting electricity to mechanical power (i.e., electric motor) or mechanical power to electricity (i.e., electric generator). The movement involved in the mechanical power can be rotating or linear.Although transformers do not contain any moving parts they are also included in the family of electric machines because they utilise electromagnetic phenomena.Electric machines (i.e., electric motors) consume approximately 60% of all electricity produced. Electric machines (i.e., electric generators) produce virtually all electricity consumed. Electric machines have become so ubiquitous that they are virtually overlooked as an integral component of the entire electricity infrastructure. Developing ever more efficient electric machine technology and influencing their use are crucial to any global conservation, green energy, or alternative energy strategy.
