Device for measurement of the torque applied to a shaft, e.g. for determining the torque applied to a motor vehicle steering wheel shaft, has a stator arrangement with inner and outer fingers for increasing measurement sensitivity

摘要

Device for determining the torque between two shaft sections, which move relative to each other, comprises a multipolar magnetic ring (24) arranged around the first shaft section (14) and a stator support (30) with two stator elements (26, 32) fixed to the second shaft section (12). Each stator has axially extending fingers equally distributed around its circumference. The fingers (36) of a first stator element are arranged radially further out than those (34) of the second stator element.
