Abstract:
1. A system, especially adapted for high-power motors comprising at least one rotor ( 1 a ; 1 b ) and means ( 4 a , 4 b ; 5 a , 5 b ) comprising active elements ( 7 , 8 ) capable of rotating the rotor(s) ( 1 a ; 1 b ) by their synchronized deformation, said rotating means of the rotor(s) comprising at least one petal ( 6 ) comprising a hot top ( 11 ), characterized in that the material of each hot top ( 11 ) is such as that it has a mass thermal capacity (Cp 22C ) of greater than 0.35 [J/g/K], and/or the material of each rotor ( 1 a ; 1 b ) is such that it has a thermal capacity of greater than 2 [J/cm 3 /K].
