摘要： The invention relates to a position sensor which is intended, in particular, for detecting a steering column torsion. The invention consists of: a first magnetic rotor structure (10) comprising a plurality of radially-oriented magnets; a second stator structure comprising two rings (23, 24) which extend into axially-oriented overlapping teeth (25, 26); and a third fixed collector structure (30) comprising two flux-closing parts which define at least one air gap in which at least one magneto-sensitive element is placed. The invention is characterized in that the flux-closing parts and the stator rings (23, 24) define therebetween a constant collection surface that is independent of the relative radial position of the two structures.

A relation between the magnetized width Y.sub.a measured on the mean diameter of the magnets, the width of the angular arc C through which the rotor passes on the mean diameter of the magnets, the width S measured on the mean diameter of the magnets between two adjacent stator poles, the radial length of the magnets L, and the constant length E of the air gap is:Y.sub.a =C+S +2 E'where E' is between E/2 and E. Furthermore, C+2 E'/E >6 and L/E>0.75.

摘要： A method for controlling a polyphase actuator includes supplying each phase with a periodically varying voltage having a periodic sequence of steps Pi that have a constant duration and an amplitude An,i, where n corresponds to the rank of the phase and i to the rank of the step. The method further includes determining a target position PCi of a rotor of the actuator, in order to define a sinusoidal voltage envelope. The actuator further includes a movable member, a stator equipped with electrical coils and a sensor detecting the mechanical position of the movable member with respect to the stator, as well as a microcontroller. The microcontroller determines, at times Tcapteur, a mechanical position of a mechanical member, the microcontroller calculates, at each of the times Tcapteur, a difference between the mechanical position and a target position PCi corresponding to the step Pi and the microcontroller calculates a coefficient k as a function of the difference. The microcontroller also weights the amplitude of a power supply applied to the phases by a coefficient k in order to supply the phases with weighted amplitude voltages An,i*k.

摘要： The disclosure relates to a valve for controlling the circulation of a fluid, having a valve body and a housing containing an electric motor composed of a stator and of a rotor, a needle, a sealing bell and also a fixed screw or a fixed nut. The fixed screw or the fixed nut is secured to the valve body, and the stator is secured to the valve body via the housing. The sealing bell is positioned at the interface between the rotor and the stator in such a way that the screw/nut, the rotor and the needle are within this bell and submerged in the fluid, the stator being isolated from the fluid. Furthermore, the rotor has the function of a nut or of a screw, and has a helical movement imposed by the fixed screw or the fixed nut and drives the needle axially. The motor is a brushless polyphase motor with radial principal magnetic flux.
