WebThe exciter can be a dc generator or it can be an alternator that uses diodes to convert its output to dc. The net result is the required dc that is used to create the rotor field. Figure 2 …

For a machine using field coils, as is the case in most large generators, the field must be established by a current in order for the generator to produce electricity. Although some of the generator's own output can be used to maintain the field once it starts up, an external source of current is needed for starting the generator. In any case, it is important to be able to control the fiel… WebOct 24, 2024 · DAYTON AUDIO DAEX58FP Speaker Driver Exciter Bodyshaker 25W 8 Ohm Ø5.8cm - reviews - There are 2 reviews.
