Title:
MAGNETOELASTIC NON-CONTACTING TORQUE TRANSDUCER
Document Type and Number:
WIPO Patent Application WO/1995/027191
Kind Code:
A1
Abstract:
A 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 U 45°.
