Multifunctional torque sensor |
摘要 |
A multifunctional torque sensor comprises a torque transmission shaft, a rectangle-shaped or parallelogram-shaped magnetic material strip bonded on the surface of the torque transmission shaft so that opposite sides of the rectangle or parallelogram face each other with a gap interposed therebetween, a first coil concentrically wound around the magnetic material strip, amagnetic core disposed outside of the magnetic material strip in no contact therewith through a space, and a second coil wound around the magnetic material strip. A change in magnetic characteristic caused by a stress transmitted from the torque transmission shaft to the magnetic material strip is detected by the first coil, thereby detecting a torque. The rotation of the shaft is detected through the detection of the gap by the second coil upon rotation of the shaft. A power can be operationally determined from the detected torque and rotation.
