Abstract

A device for measuring the angular acceleration of a rotary shaft, comprising a magnetic circuit provided with an air gap in which a drum of conductive material, mechanically coupled to the shaft, is designed to rotate and which comprises a stationary coil to be connected to a meter, said coil being magnetically coupled with the field that is produced in the rotation of the drum due to the parasitic currents produced therein, characterized in that the closed magnetic circuit comprises one or more permanent magnets and is provided with two poles, of magnetic material non-permanent, which limit a cylindrical space in which a cylindrical core of non-permanent magnetic material is arranged so that a cylindrical space is left in which the rotor is intended to rotate, while the coil (s) is ( are) disposed in one or more slots disposed in a substantially symmetrical position in the pole system, such as The transverse field essentially closes completely through the non-permanent magnetic material.
