Abstract :
Starting with the theory of operation of a-c commutator machines, it is shown how either a single or polyphase generator can be built whose frequency is controllable and essentially independent of speed and whose general characteristics are similar to those of a d-c generator. Among the principal topics discussed are The generated voltage equation-Voltage regulation. Parallel operation. Compensating windings. Motor operation. Commutation. Compounding. Self-excited operation.
