Title
(EN) SMART ELECTRIC MOTOR WITH DECOUPLED MULTIPLE WINDINGS
(FR) MOTEUR ELECTRIQUE INTELLIGENT A MULTI-BOBINAGES DECOUPLES
Abstract
(EN)
A smart motor (10) comprising a permanent-magnet synchronous machine (12, 12', 12") and an electronic control unit (18), the synchronous machine (12, 12', 12") comprising one or two permanent-magnet rotor(s) (121, 1211, 1212) and at least one hexaphase stator (122, 1221 to 1224) per rotor equipped with at least two three-phase assemblies (123, 124) each formed of three coils (1230, 1240) that are electrically coupled in star configuration, said electronic control unit (18) comprising one control inverter (184) per stator provided with six independent arms (1840) each configured so as to drive a phase of a hexaphase stator (122, 1221 to 1224). The three-phase assemblies (123, 124) are magnetically and electrically decoupled from one another.
(FR)
Un moteur intelligent (10) comprenant une machine synchrone à aimants permanents (12, 12', 12") et une unité électronique de commande (18), la machine synchrone (12, 12', 12") comportant un ou deux rotor(s) (121, 1211, 1212) à aimants permanents et au moins un stator hexaphasé (122, 1221 à 1224) par rotor doté d'au moins deux ensembles triphasés (123, 124) formés chacun de trois bobines (1230, 1240) électriquement couplées en étoile, ladite unité électronique de commande (18) comportant un onduleur de commande (184) par stator muni de six bras (1840) indépendants configurés chacun pour piloter une phase d'un stator hexaphasé (122, 1221 à 1224). Les ensembles triphasés (123, 124) sont découplées magnétiquement et électriquement l'un par rapport à un autre.
