the magnet. The frequency of the induced EMF will depend upon the number of magnetic poles
confronted by the coils per revolution. Normally, the number of magnetic poles and the speed
of rotation of the magnetic poles by a drive, usually a turbine, are kept constant. The number
of coils and number of turns used in each coil are kept as per design and are constant once
the machine is constructed. That is the reason why the magnitude of the induced EMF and its
frequency are constant. Thus, we get a single-phase voltage from the single-phase windings
that can be used to supply an electric circuit comprising ...
