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 said shaft, can rotate, and comprises a stationary coil to be connected to a meter said coil being magnetically coupled to the field produced when the drum is rotated, by the eddy currents produced therein, characterized in that the drum can rotate with a small intermediate space inside a cylindrical box and because two poles are provided inside the drum. magnetized permanents arranged relatively symmetrically and because the coils are arranged on a non-permanent magnetic core, whose axis is at right angles to the axes of the poles and the ends thereof are at a small distance from the inner side of the drum.
