Patentanspruch:Claim:Anordnung zur Unterdrückung von Oberwellen an Drehstromxeibenschlufimotoren
mit Zwischentransformator und Sechsbüirsitenschaltung, dadurch gekennzeichnet,
daß die den Kommuitatorstrom
führenden einzelnen Phasenleitungen mit den Wicklungen einer dreiphasigen Eisendrosselspule
in Reihe geschaltet sind, die derart bemessen und geschaltet sind, daß die magnetischen Wirkungen der normalen
Mehrphasenströme sich infolge ihrer gegenseitigen Phasenverschiebungen an der Drosselspule aufheben, während die
magnetisichen Wirkungen ein oder mehrerer Oberwellensitröme sich addieren.Arrangement for the suppression of harmonics on three-phase external motors
with intermediate transformer and six-office circuit, characterized in that
that the commuitator current
leading single phase lines with the windings of a three-phase iron choke coil
are connected in series, which are dimensioned and connected in such a way that the magnetic effects of the normal
Multi-phase currents cancel each other out due to their mutual phase shifts at the choke coil, while the
Magnetic effects of one or more harmonic currents add up.
