Methode der elektrischen Energieübertragung
Nikola Teslas Erfindung beschreibt eine neue und verbesserte Methode zum Starten und Betreiben von Elektromotoren, die synchron mit Stromgeneratoren arbeiten. Normalerweise können diese Motoren nicht von selbst mit Wechselstrom anlaufen und benötigen zusätzliche Geräte oder komplizierte Vorrichtungen, um in Gang zu kommen. Teslas Methode vereinfacht dies, indem sie vorübergehend eine spezielle Verbindung zur Erde herstellt, die es dem Motor ermöglicht, zu starten. Sobald der Motor die richtige Drehzahl erreicht hat, wird diese Masseverbindung abgeschaltet, und der Motor läuft gleichmäßig und synchron mit dem Generator weiter. Dieser Ansatz ist wertvoll, weil er einen flexiblen und effizienten Wechsel zwischen zwei verschiedenen Arten von Stromkreisen ermöglicht, was den Einsatz dieser Motoren in der Praxis erleichtert.

Dynamo-Electric Machine
Relates to class of machines referred to as "Unipolar" machine (i.e., a disk or cylindrical conductor is mounted in between magnetic poles adapted to produce a uniform magnetic field); Construction of a machine with two fields, each having a rotary conductor mounted between its poles; Discussed the disk form primarily; The direction of the magnetism or order of the poles in one field of force is opposite to that of the other, so the rotation of the disk in the same direction forms a field from the center to the circumference and another from the circumference to the center; Contacts applied to the shafts form terminals of a circuit to produce a sum of electromotive forces of the two disks; If direction of the fields are the same, driving the disks in the opposite direction will obtain the same results.
