20DAM-K - Linearschrittmotoren

20DAM-K

Der kleinste unserer Linearaktuatorreihe ist der 20DAM-K, ein Hochleistungs-Miniaturlinearaktuator mit Verdrehsicherung, der bis zu 30,6 N lineare Kraft aus einer 20-mm-Gehäusegröße liefert.

Motor Highlights

  • Für die Baugröße hohe kontinuierliche lineare Kraft

  • Digitale Steuerung - einfache Anwendung mit einem Mikroprozessor

  • Kosteneffektiv - kompakte Ausführung, niedrige Integrationskosten

  • Wartungsfrei - kein Bürstenwechsel erforderlich

  • Uni- und bipolare Wicklungsoptionen

  • Linearaktuatorausführungen mit und ohne Verdrehsicherung

  • Hohe Lebensdauer - Kugellagerausführung

Kundenspezifische Lösungen

  • Spulenmodifikationen - Widerstand und Induktivität.
  • Magnete - erzeugen eine höhere lineare Kraft oder reduzierte Rastmomente
  • Kunststoff mit höherer Festigkeit für höhere Stoßkräfte
  • Zur Anwendung passendes reduziertes oder erhöhtes Rastmoment
  • Gewindespindel - Spitze in metrischer oder imperialer Ausführung, Länge
  • Sonderflansche, Steckverbinder, Bewegungsende-Erkennungssensoren
  • Kabelbaum - Steckverbinder, Kontaktstifte, Leitungslänge, Schrumpfschlauch
