How do armatures and field magnets differ in dynamos and alternators?
This board contains all indicating instruments for alternators and feeders.
The principles of alternators have been considered also transformers and their applications.
The alternators have forty field poles and operates at seventy-five revolutions per minute.
The alternators, of course, are separately excited, the potential of the exciting current used being 250 volts.
It must have been a terrible job to synchronize those two alternators, commented Joe.
Generators are designed either to give steady streams of electrons, that is for d-c currents, or to act as alternators.
Three-wire transmission systems, alternators, construction, and action.
The several phases may be entirely independent, and such was the case with the early polyphase Quarter-phase alternators.
If the current in coil A (fig. 41) is flowing away from the centre, and has its maximum value, the Three-phase alternators.
