Abstract :
A torque sensor employing amorphous ribbons (FeCoSiB) bonded to the rotor shaft for use in induction motors, is described. Magnetic field annealing is used to induce an anisotropy in the ribbons which were relatively Co-rich composition. By using more than one sensor head, the influence of magnetic fields generated by the motor can be suppressed. Output averaging yielded good linearity, high accuracy (±0.07 kg-m) and satisfactory sensitivity (22.4 mV/kg-m).
