CA 2322851
An induction machine (20) adapted for variable speed operation, including low and zero speed, comprising: a polyphase stator having two separate stator windings (abc, xyz) with separate input terminals for each winding by which drive power may be applied separately to the two windings, wherein the two windings have different number of poles that are in the ratio 1:3 and a squirrel cage rotor mounted within the stator.
L'invention concerne une machine à induction (20) conçue pour fonctionner à vitesse variable, notamment à une vitesse faible ou nulle, cette machine comprenant: un stator polyphasé pourvu de deux bobinages statoriques séparés (abc, xyz), qui présentent chacun des bornes d'entrée séparées permettant d'appliquer séparément une puissance de commande à ces deux bobinages, qui comportent par ailleurs un nombre différents de pôles, selon un rapport 1:3, un rotor en cage d'écureuil étant en outre monté à l'intérieur dudit stator.
