Title: Cyclic magnetic field generating device
Inventor: TANAKA TOSHIJI
IPC: H01J23/087
Filed: 1988-12-21
Abstract: PURPOSE:To easily provide a uniform on-axis mag. field distribution by arranging a plurality of shims having a body in specific shape at a certain spacing in the axial direction, and using permanent magnets in the same shape which allows tight fit in the space between adjoining shims. CONSTITUTION:A plurality of shims 12 are arranged at a certain spacing on one axis with spacers 13 interposed. The body 12A of each shim 12 reduces its thickness in axial direction from the internal end toward the external so as to assume a taper. A plurality of ring-shaped permanent magnets 11 in an identical form are fitted between adjoining shims. The permanent magnets 11 are in close contact with respective shims. Thereby the magnetic resistance to the flux leaking to the outside can be increased compared with the case in which the thickness in the axial direction is uniform, and accordingly the leak mag. field is reduced. This lessens the influence of the leak mag. field upon the on-axis mag. field distribution, which will thus be more uniform.

Abstract: PROBLEM TO BE SOLVED: To provide a submergible magnetic bearing device of simple construction and low cost by using a cable covered with a metallic sleeve through insulating material for a coil, and using a seal member at the through part of a casing for taking out the cable outward. SOLUTION: A projection 4a projecting from a stator 4 toward a rotor yoke fixedly secured to a rotary shaft is wound with a cable 6 covered with a metallic sleeve through insulating material such as magnesium oxide, so as to constitute a coil 5. Because the cable 6 is covered with a metallic sleeve through the insulating material, it can be used in water as it is without covering with a cover and the like. A seal member is used at the through part of a casing for taking out the cable 6 outside a casing, and hence water and the like is not leaked outward from the part for taking out the cable 6 outside the casing.
