Abstract
Variatore di velocità elettrico controllato che comprende un primo albero che supporta un primo pacco lamellare di materiale ferro-magnetico conformato a campana con cava assiale cilindrica, dotato di avvolgimenti di eccitazione, ed un secondo albero, in asse e consecutivo al primo albero, su cui è calettato un rotore lamellare inserito entro la cava assiale definita dal primo pacco.Il detto rotore può essere a gabbia di scoiattolo o di tipo avvolto.Il primo pacco lamellare costituisce statore rotante per il detto rotore cui impone una velocità angolare relativa in funzione delle caratteristiche elettriche e della frequenza di alimentazione del campo magnetico statorico.La velocità angolare del campo magnetico statorico si somma, algebricamente alla velocità angolare applicata al primo albero.Convenientemente sono previsti mezzi di ventilazione.Electric controlled speed variator that includes a first shaft that supports a first lamellar pack of iron-magnetic bell-shaped material with a cylindrical axial slot, equipped with excitation windings, and a second shaft, in axis and consecutive to the first shaft, on which a lamellar rotor inserted inside the axial slot defined by the first pack is keyed. The said rotor can be squirrel-cage or wrapped type. The first lamellar pack constitutes a rotating stator for the said rotor to which it imposes a relative angular speed according to the characteristics. and the frequency of the stator magnetic field supply. The angular velocity of the stator magnetic field is added algebraically to the angular velocity applied to the first shaft. Ventilation means are provided.
