Abstract (en)
[origin: WO2010106252A2] The invention relates to a rotation measuring device comprising at least one ball (1), each ball being magnetised or temporarily magnetised in such a way as to have a dipolar magnetisation. The ball (1) can rotate freely in a recess (6) of a frame (10), the device comprising means (5) for detecting a magnetic field created by the at least one ball (1), according to at least three non-coplanar axes extending in different directions.
