Title: MAGNETIC TRANSMISSION SYSTEM
Abstract:
The present invention relates to a transmission system between an input shaft and an output shaft consisting of a driving ferromagnetic portion 2, a driven ferromagnetic portion 1 and an intermediate ferromagnetic portion 3, these three portions 1, 2, 3 being movable with respect to one another; - one of said portions 1 having N pairs of magnetic poles interacting with a second of said portions 3 having M ferromagnetic parts, where M•N; - said second portion 3 interacting with a third of said portions 2 having P pairs of poles; - at least one portion of said parts including a permanent magnet; - and at least one portion of said parts being made up of a polar tooth bearing an electrical coil, characterized in that said system additionally includes a means for detecting forces applied between said input shaft and said output shaft that is made up of a means for measuring the electromotive force flowing through at least one of said coils, and a means for controlling the supply of power to said electrical coils in order to control the magnetic power delivered by said permanent magnets and the polar teeth excited by electrical coils, according to a setpoint value and to the signal provided by said force detection means.
