    Abstract: PROBLEM TO BE SOLVED: To provide a torque converter capable of selecting the material of converting shaft independently from the magnetic characteristics of the material. SOLUTION: The torque converter whose magnetoelastic region 2 formed in a cylinder shape is permanently magnetized in the azimuth direction and has a converting shaft 1 arranged together with a magnetoelastic region 2 formed in cylinder fixed around the cylinder of the converting shaft 1. The converting shaft 1 provided with the magnetoelastic region 2 formed in cylinder is surrounded by a winding 4 supplied by alternating current. The winding 4 is connected to a phase detector 5. With this invention, magnetism and a nonlinear ferromagnetic material 3' physically contact the magnetoelastic region 2 formed in cylinder.

    Abstract: PCT No. PCT/SE95/00289 Sec. 371 Date Sep. 4, 1996 Sec. 102(e) Date Sep. 4, 1996 PCT Filed Mar. 22, 1995 PCT Pub. No. WO95/27191 PCT Pub. Date Oct. 12, 1995A magnetoelastic torque transducer for measuring, in a non-contacting manner, the torque in a stationary or a rotating shaft. The transducer comprises a shaft (1) with surrounding excitation windings (2, 3) and measuring windings (10, 11). Concentrically with the windings, anisotropic measuring zones are created by applying layers (8, 9), for example in the form of copper strips, on the surface of the shaft. The angle between the strips and a generatrix to the cylinder surface of the transducer shaft is in a preferred embodiment chosen to be +/-45 DEG (FIG. 5).

    Abstract: The present invention relates to a magnetostrictive sensor for measuring a torque in a shaft. The sensor comprises at least one active magnetostrictive region on the shaft, a surface pattern in the magnetostrictive region such that it obtains anisotropic properties, a first means arranged to generate a magnetic field varying in time in the magnetostrictive region and a second means arranged to sense variation in the permeability in the magnetostrictive region. Said magnetostrictive region comprises a first layer of a magnetostrictive material which is provided on the surface of the shaft and that said surface pattern is formed by a second layer of a non-magnetostrictive material comprising a low resistivity.

    Abstract: The present invention relates to a sensor for measuring stresses induced by a force applied to a load-carrying member. The sensor includes a layer of a magnetoelastic material formed on the load-carrying member. The layer is inhomogeneous and comprises a first phase with an average grain size below 100nm and a first chemical composition, and a second phase (17) of a distinctly different chemical composition, the first phase being divided by the second phase into regions (18) having an average size in the range of 100 - 10 000nm, and a plurality of the regions have an oxygen level less than 1wt%. The present invention also relates to a method for producing such a layer. The method comprises accelerating particles of a soft magnetic and magnetoelastic material having an average size in the range of 10-50µm towards the surface of the load-carrying member at a velocity of at least 300m/s such that the average temperature of the accelerated particles is not higher than 500°C above the melting temperature of the magnetoelastic material, but not lower than 500°C below the melting temperature of the magnetoelastic material.
