<p>The invention relates to a mono-phase magnetostrictive micromotor meant for the conversion of the vibration movement, produced by a vibratory motor, into a continuous rotation or linear movement. According to the invention, the micromotor consists of a disk-shaped rotor (1), integral with an axle (2), supported by means of some slide bearings (3 and 3'), said rotor (1) having a friction ring (4) attached on its surface, on the said ring there are supported some friction spurs (5, 5' and 5'') which are driven by means of some magnetostrictive vibratory motors (A, B and C), with the axes shifted in space, at 2π/3 radian, each vibratory motor consisting of a terfenol bar (6, 6', 6'') which is under the action of some magnetic fields, shifted in time, generated by some coils (7, 7', 7''), made on some casings (8, 8', 8'') made of electro-insulating material, each casing being mounted on a terfenol bar, the magnetization system of each terfenol bar being provided with a cup-shaped ferromagnetic armature (9, 9', 9'') closed at the upper side by a cover (10, 10', 10'') wherein there is embedded the corresponding terfenol bar.</p> |
