Abstract
The utility model provides a magnetoelectric coriolis force detection sensor which comprises a shell, a mass body and a magnetostriction-piezoelectric detection sensor mechanism, wherein the mass body and the magnetostriction-piezoelectric detection sensor mechanism are arranged in the shell. The magnetoelectric coriolis force detection sensor is capable of realizing low-speed or high-speed broadband rotating speed detection of a flat rotation body (shell) based on a coriolis force effect. As Fc=-2m (w*v), when m is constant, the value of coriolis force is decided by the moving speed v of a mass point (mass body) and the angular speed w of a rotating system (shell); when w is smaller (the rotating speed of the flat rotation body is slow), or w is larger (the rotating speed of the flat rotation body is rapid), the optimized corresponding frequency spectrum relationship between w and v can be obtained by correspondingly accelerating or slowing down the moving speed v of the mass point, so that the stable coriolis force can be obtained, and slow or rapid rotation detection of the flat rotation body can be further realized.
