Abstract: La présente invention concerne une machine électrique comprenant un rotor (10) et un stator (12). Le stator (12) comporte plusieurs passages radiaux (28), plusieurs générateurs de flux magnétiques ou bobines (34), logés dans lesdits passages radiaux (28), et un manchon (24) tubulaire interne recevant ledit rotor (10). Lesdites passages radiaux (28) comportent les galeries de circulation d'un fluide (36) en regard des bobines (34).
