Definitions

  • a first object of the invention is a linear actuator comprising one or more coils mounted to a first coil back iron; one or more coils mounted to a second coil back iron; two or more magnets positioned in the centre between the first coil back iron and the second coil back iron; a first air gap between the first coil back iron and the magnets; a second air gap between the second coil back iron and the magnets; the first air gap and the second air gap being the same width; and a structure that holds the magnets in place, the structure having a first bushing mounted on a first fixed shaft and a second bushing mounted on a second fixed shaft; so that the structure glides along the first fixed shaft and the second fixed shaft from a first position to a second position and back when a current passes through the one or more coils.

Abstract

L'invention porte sur un actionneur linéaire ayant une ou plusieurs bobines 21a montées sur une première culasse magnétique de bobine 22a ; une ou plusieurs bobine montées 21b sur une seconde culasse magnétique de bobine 22b et au moins deux aimants 23a, 23b entre la première culasse magnétique de bobine 22a et la seconde culasse magnétique de bobine 22b. Un premier entrefer entre la première culasse magnétique de bobine 22a et les aimants 23a, 23b et un second entrefer entre la seconde culasse magnétique de bobine 22b et les aimants 23a, 23b ont la même largeur. Une structure 24 maintient les aimants 23a, 23b en place avec une première bague 25a sur un premier axe fixe 26a et une seconde bague 25b sur un second axe fixe 26b. Lorsqu'un courant passe à travers les bobines 21a, 21b, la structure 24 glisse en va-et-vient le long du premier axe fixe 26a et du second axe fixe 26b.
