ther as are the primary andthe secondary of an alternating-current transformer. The result is,that when the field coils have many turns of wire, a dangerouslyhigh electromotive force may be induced in them. This production of high voltages in the field coils of a self-started polyphase synchronous… … ALTERNATING-CURRENT MACHINERY 223 stationary field of an alternator (synchronous motor) with the ter-minals of each field spool brought out to convenient switches onthe frame of the machine. During starting these switches are open,and when the machine has reached synchronous speed, they are…
