Internal pole generator
An internal pole generator ( internal pole machine ) is the designation of an electrical generator in which the coils or the permanent magnets for the excitation field are placed in the rotor . In this case, the magnetic field lines of the rotor penetrate the windings of the stator and induce an alternating voltage in them . The direct current supply to the rotor is often done via slip rings from an exciter , which are on the same axishow the generator sits. This principle is implemented in most power plants . In the case of new power plants, however, for reasons of dynamism, one goes back to static excitation .
The generator constructed in the opposite way is called the external pole generator .
