Abstract:
An electromechanical transducer comprising a stator and first and second rotors controlled independently of each other and comprising respectively first and second bipolar permanent magnets having radial magnetisation, said stator defining first and second stator holes within which are respectively situated said first and second permanent magnets,wherein said stator comprises a first part defining first, second and third magnetic poles, said first and second magnetic poles entirely defining said first stator hole and said second and third magnetic poles entirely defining said second stator hole, said first, second and third magnetic poles being respectively connected to the first ends of first, second and third magnetic cores respectively bearing first, second and third independent coils, the second ends of said first, second and third magnetic cores being connected to a second part of the stator used for closing the magnetic circuits of said electromechanical transducer, andwherein said first and third coils are connected to supply means arranged for supplying said first and third coils so as to actuate respectively said first and second rotors andsaid second coil is connected to means for selectively detecting the rotation of said first and second rotors.
