Abstract

The Giant Magneto-Impedance (GMI) torque transducer module with frequency modulation (FM) transmitter is proposed for the first time to detect the torque from a rotating shaft. The proposed transducer module has advantages such as simple construction without the torsion bar, high accuracy, low power consumption and an easy installation. The operation of FM transmitters, which is based on Complementary metal Oxide semiconductor (CMOS) inverters, is analyzed. The proposed circuit design allows the module to be fabricated in a single Integrated Circuit (IC). Basic experiments for signal transmission were carried out. The linear frequency modulation with the applied torque is achieved in the torque range of – 5 Nm for a 13 mm diameter brass shaft..
