Paper Abstract
In order to raise the stress measurement sensitivity based on magnetoelastic effect, a new kind of whole differential
magnetoelastic stress sensor with five magnetic poles is designed. First the author introduced the basic sensor structure,
the size parameter and the choice of the magnetic core material, and then according to the magnetoelastic effect carried
on analysis to the work principle of the sensor, making use of electromagnetism and principle of superposition again
inferred the sensor voltage output equation as well as the current sensitivity formula. Finally, the author make a actually
measure, and the test result indicated that the actual torques tested by using the magnetoelastic stress sensor made by
author with the result of calculation is consistent. Compared with other magnetoelastic stress sensors, the sensor
designed by author has simple structure, is easier to manufacture, more precise and sensitive. These characteristics can
satisfy the request of engineering application and it is the worth to popularize.
