ABSTRACT:
A torque sensor has a contoured magnetoelastic element that generates a magnetic field having a shape that exhibits gradual changes rather than sharp peaks in the axial direction, making the torque sensor less sensitive to positional changes between the magnetoelastic element and a magnetometer in the sensor. The element is contoured in any desired shape to modify the magnetic field generated by the element when it is deformed through applied torque. In one embodiment, the element is a magnetic material coating applied to a contoured shaft.
