Abstract
Official abstract text for this publication.
A magnetic hysteresis brake includes a stator equipped with at least one control coil and a rotor mounted to be mobile facing poles of the stator, wherein the brake includes at least one magnet mounted on the stator facing the rotor and having a sufficient power to locally generate, in the rotor, a level of induction substantially equal to a maximum level of induction generated by the coil when the latter is powered.
First claim
Opening claim text (preview).
1 - 5 . (canceled) 6 . A magnetic hysteresis brake comprising a stator equipped with at least one control coil and a rotor mounted to be mobile facing poles of the stator, the brake comprising at least one magnet mounted on the stator facing the rotor and having a sufficient power to locally generate, on the circumference of the rotor, a level of induction substantially equal to a maximum level of induction generated by the coil when the latter is powered, the rotor having an annular form and being received to pivot about its central axis in a circular groove of the stator, the groove having flanks provided with reliefs forming the poles of the stator, the brake comprising at least one magnet mounted on one of the flanks of the groove, wherein the brake comprises two magnets each mounted on one of the flanks of the groove. 7 . The brake according to claim 6 , wherein the magnets mounted on the flanks of the groove are positioned substantially facing one another. 8 . The brake according to claim 6 , wherein the at least one magnet mounted on the stator is mounted between two poles of the stator.
