    • A cylindrical yoke of an electromagnet consists of two or more yoke elements, each of which is made of a number of yoke pieces made of magnetizable metal sheets and arranged radially around a cylindrical coil member of the electromagnet and of a filler member unifying the yoke pieces. The thickness of the yoke piece increases with increasing radial distance in order to improve the space factor of the yoke. The eddy current generated in the yoke is reduced due to the laminated construction of the yoke. The yoke disposed close to and coaxially with the coil member also contributes to the radial dispersion of the heat generated in the coil member and the yoke. The improved space factor results in the reduction of the leakage flux of the electromagnet and of the outermost size of the electromagnet for a certain available actuating power.
    • 电磁体的圆柱形磁轭由两个或更多个磁轭元件组成,每个磁轭元件由多个由可磁化金属片制成的轭件制成,并且围绕电磁体的圆柱形线圈构件径向设置,并且将轭片 。 磁轭的厚度随着径向距离的增加而增加,以提高磁轭的空间系数。 由于轭的叠层构造,在轭中产生的涡流减小。 设置在线圈构件附近并同轴的轭也有助于在线圈构件和轭中产生的热的径向分散。 改善的空间因素导致电磁体的漏磁通量的降低以及电磁体的最外部尺寸对于某些可用的致动力的降低。
