The magnetic loop consists of a conductive loop that is separated at one end by a capacitor, thus forming an LC circuit that has to resonate at the operating frequency of the antenna. A smaller loop is positioned towards the opposite end of the capacitor within the area of the main larger loop.
Half-open type thrust magnetic levitation bearing
The invention discloses a half-open type thrust magnetic levitation bearing. The bearing comprises a first magnetic ring, a second magnetic ring and a third magnetic ring, wherein the first magnetic ring, the second magnetic ring and the third magnetic ring are arranged in annular and laminating manners so as to form an annular magnetic pole; the magnetic pole of each of the magnetic rings is different from that of the adjacent magnetic ring; a first winding and a second winding of the annular magnetic pole are wound according to a predetermined half-open way, the lower part of the middle magnetic pole is recessed inwards so as to generate a winding space which meets predetermined conditions; and the magnetic pole arranged at the upper end extends, and thus, a complete circle of magnetic pole is formed after splicing. Based on the bearing, continuity and consistency of magnetic field strength of the magnetic poles of the half-opened axial thrust bearing can be basically reserved, and the half-open type thrust magnetic levitation bearing can be applied to high-speed rotation machines; and moreover, a more flexible mounting way can be obtained, particularly to large-size rotation machines.
