English: A rotating magnetic field is a magnetic field which periodically changes direction. This is a key principle to the operation of alternating-current motor. In 1882, Nikola Tesla identified the concept of the rotating magnetic field. In 1888, Tesla gained U.S. Patent 381968 for his work. ....
Deutsch: Elektromagnetischer Motor, U.S. Patent 381968 für Nikola Tesla. Zeichnung aus der Patentschrift. Links: Schaltung und Geometrie des Elektromotors (ringförmiger Eisenkern mit 4 Spulen, linearer Rotor). Rechts: Generator (Rotor zwischen Polschuhen eines Magnets, mit um 90° versetzten Induktionsspulen, kontaktiert über 4 Schleifringe (in der Zeichnung teilweise aufgeschnitten, um die Anschlüsse zu zeigen), Abgriff über 4 Bürsten). Darunter in 8 90°-Schritten (I–VIII): Positionen der 2 Generatorspulen und über die 2 (getrennten) Wechselstromkreise und 4 Motorspulen erzeugte Orientierung des Magnetfelds im Luftraum (!) innerhalb des Magnetrings. Anzunehmen ist das Fließen von zwei um 90° zeitverschobenen Wechselströmen in den 2 Stromkreisen und das Mitnehmen des linear erstreckten Motorrotors. Nicht dargestellt ist, ob dieser aus Weicheisen oder einem Permanentmagnet besteht. |
