Title
(EN) TORQUE SENSOR
(FR) DETECTEUR DE COUPLE
Abstract
(EN) A torque sensor which can detect torque based on the variation of the magnetic reluctance of a magnetic circuit. At least one of the constituent members of the magnetic circuit is formed by molding a magnetic material prepared by dispersing magnetic powder in a base material composed of a synthetic resin.
(FR) L'invention porte sur un détecteur de couple fonctionnant sur la base des variations de réluctance magnétique d'un circuit magnétique. L'un au moins des éléments constitutifs du circuit magnétique se prépare en dispersant une poudre magnétique dans une base de résine synthétique.
