本文介绍的退磁机是由铁芯和线圈组成,它象一只具有空气隙的铁芯匝扼流圈,铁芯通常由厚度0.35毫米的矽钢片叠成C字型式。当线圈通以正弦50赫芝的交流电时,在空隙处产生强度较大的交变磁场,轴承零件通过这一磁场将受到一个数值上递减而方向上不断变化的磁场的作用,使其剩磁随之减弱直至某个最低限度,从而完成退磁目的。退磁机的主要参数为:窗口尺寸80×350×130毫米;冷却方式为空气自冷式;二个线圈并联,每个线圈匝数为135—150;电压为50赫芝380伏的交流电;磁感应强度为900～1000高斯。退磁机可连续工作8小时。附图4幅,表1个。
This article describes the demagnetization machine is composed of iron core and coil, it is like an air-gap iron core choke, the core is usually the thickness of 0.35 mm laminated silicon steel into C-shaped. When the coil through the sinusoidal 50 Hertz AC, in the gap to produce a larger alternating magnetic field, the bearing parts through the magnetic field will be subject to a numerical decrease in the direction of the changing magnetic field, the residual magnetism Then weakened until a certain minimum, thus completing the purpose of demagnetization. The main parameters of the demagnetizer: window size 80 × 350 × 130 mm; cooling mode is air-cooled; two coils in parallel, each coil turns 135-150; voltage of 50 Hertz 380 volts AC; magnetic induction Intensity 900 ~ 1000 gauss. Demagnetizer can work continuously for 8 hours. Figure 4, Table 1.
