Apparatus for sensing position and/or torque |
摘要 |
An apparatus measures relative displacement between a first end and a second end of a shaft. The first and second ends being centered on a shaft axis. The apparatus includes first and second ferromagnetic plates. The first ferromagnetic plate has a first side and a second side and is connected to the first end. The first ferromagnetic plate is centered on the shaft axis and has a plurality of ferromagnetic teeth extending from the first side and in a first direction parallel to the shaft. The second ferromagnetic plate has a first side and a second side and is connected to the second end. The second ferromagnetic plate is centered on the shaft axis. The first and second ferromagnetic plates form a gap. The apparatus further includes a plurality of magnets having a magnetic field and a sensing device. The magnets are coupled to the first side of the second ferromagnetic plate. The sensing device is disposed within the gap for sensing a magnetic flux of the magnetic field.
