Circularly magnetized non-contact torque sensor and method for measuring torque using same

摘要: A torque sensor (2) comprises a magnetoelastically active element (4), and magnetic (6) responsive to the field of portion. The portion ring material (4) endowed with an effective uniaxial anisotropy such that circumferential direction is easy axis, magnetically polarized in substantially direction. attached torqued member (8), as rotating shaft, so application shaft transmitted ring. vector mounted fixed position relative oriented it responds maximally only due axial magnetization components (4). output thus proportional change orientation resulting from applied (8) may include two or more axially distinct, contiguous, oppositely regions (104, 105).
