IPC: H01F7/06
Filed: 1992-06-26
Abstract: PURPOSE:To minimize the effect of the saturation of the end parts of magnetic poles or the effect of an eddy current, which is made to flow through the end parts of the magnetic poles, and to realize a low-cost electromagnet device by a method wherein the end parts, which are easily saturated, of the magnetic poles or roughly the whole of the magnetic poles are/is constituted of a material, such as pure iron, which is hardly saturated. CONSTITUTION:The end parts only of magnetic poles 1 are respectively constituted of a block 7 consisting of pure iron or the like, which is hardly saturated, but it is high in cost, and the other parts of the poles 1 and a return yoke 2 are constituted of a low-cost low carbon steel or the like. Or, the end parts only of the magnetic poles 1 are manufactured of a high-cost thin laminated steel plate and the other parts are manufactured of a low-cost thick laminated steel plate. Thereby, the effect of the saturation of the end parts of the magnetic poles is little and the cost of an electromagnet device is not only made low but also becomes possible to suppress the effect of an eddy current, which is made to flow through the end parts of the magnetic poles, to the minimum.
