<p>The proposed magneto-mechanical converter comprises a magnet system (2) and a core (3) at least one part (34, 36) of which is made of a magneto-strictive material. The magnet system (2) comprises a main magnetic field source (4) which in the example shown can be mounted on the magnetic circuit (21). The main magnetic field source is a permanent magnet (5). The magnet system (2) is mounted in the housing (1) in such a way that it can rotate about the core (3). The geometrical axis (15) of relative rotation of the core (3) and magnet system (2) is oriented in such a way that, during the relative rotation referred to, the magnetic flux in the magneto-strictive parts (34, 36) of the core alters and in turn causes changes in the linear dimensions of the core (3). In the example shown, the magnet system (2) includes an auxiliary magnetic field source (22) in the form of a permanent magnet (5') mounted on the magnetic circuit (33). The magnetic field sources (4, 22) consist of pairs of magnetic components (23, 24, and 25, 26). The core (3) in the example shown consists of three sections (34, 35, 36), the outer sections (34, 36) being made of magneto-strictive material. In the example shown, one (e.g. auxiliary) magnetic field source (22) is mounted immovably in relation to the core (3), while a second (e.g. main) magnetic field source (4) rotates about the stationary core (3).</p> |
