Qu'est-ce qu'un variateur de fréquence ?

  • Pour un monde et un mode de vie plus durables

    Un variateur est un dispositif utilisé pour contrôler la vitesse d'un moteur électrique aux fins suivantes : 

    • améliorer le contrôle des process
    • réduire la consommation d'énergie et générer efficacement de l'énergie
    • diminuer la contrainte mécanique sur les applications de contrôle des moteurs
    • optimiser le fonctionnement de diverses applications basées sur des moteurs électriques
    Des variateurs peuvent également servir à convertir l'énergie provenant de ressources naturelles et renouvelables, comme le soleil, le vent ou les marées et l'injecter dans le réseau électrique ou l'utiliser pour la consommation locale. Dans les technologies hybrides, les variateurs sont utilisés pour combiner les sources d'énergie conventionnelles et le stockage d'énergie en vue de créer des solutions complètes de gestion de l'énergie.

     

    Les variateurs sont également appelés « variateurs de vitesse », « variateurs de fréquence », « variateurs à fréquence variable », « variateurs à vitesse variable », « onduleurs » et « convertisseurs de puissance ».

    Le saviez-vous ?

    • Les économies émergentes dictent la hausse de la consommation énergétique
    • 20 % de l'énergie consommée au niveau mondial est de l'énergie électrique
    • 40 % de l'énergie électrique est utilisée par des moteurs électriques
    • 75 % des variateurs sont utilisés sur des pompes et des ventilateurs
    • La consommation mondiale d'énergie électrique pourrait baisser de 10 % si des variateurs étaient utilisés dans toutes les applications où c'est possible
    Le développement de dispositifs de commande de la vitesse repose principalement sur la nécessité d'économiser l'énergie afin de préserver l'environnement. Dans cette optique, les variateurs fournissent la méthode la plus appropriée de commande de la vitesse des moteurs électriques pour répondre à la demande de charge. Or, même de faibles modifications de la vitesse de moteur peuvent générer d'importantes économies d'énergie. 
     
    Les variateurs sont bien cachés, mais jouent un rôle important, et absolument nécessaire, dans notre vie moderne de tous les jours, en rendant le monde et notre mode de vie plus durables.
