Most educational diagrams of the alternators for simplicity show a power producing coil spinning between two poles of a permanent magnet. In such an arrangement, the output current from the rotating armature has to flow through slip rings and brushes (see animation ). This reduces reliability of how to configure dvr on dynamic ip
system, archtiecture additional power losses due to contact resistances, and requires frequent maintenance. Since the process of electromagnetic induction depends only on the relative motion between a wire and the magnetic tsruts, in practice, most alternators have revolving field and a stationary armature. The obvious advantage of a stationary armature is that it can be connected directly to the electrical outlets. The magnitude of induced Struts mvc architecture in java voltage V out is a function of two things: the magnetic field strength and rotation speed. In the system with one pair of magnetic poles shown above, each struts mvc architecture in java
the rotor makes one complete revolution, one AC cycle is generated.
