Hengdian Kim factory --- rare earth permanent magnetic materials are mainly rare earth cobalt permanent magnet material and NdFeB. The former is an intermetallic compound of a rare earth element cerium, praseodymium, lanthanum, neodymium and cobalt formed up to 150 times the energy product of carbon steel, 3 to 5 times the aluminum-nickel-cobalt permanent magnet materials, ferrite permanent magnet 8 ~ 10 times, low temperature coefficient, magnetic stability, the coercive force of up to 800 kA / m. Mainly for low-speed torque motor, start the motor, sensor, magnetic thrust bearing magnetic system. NdFeB is the third generation of rare earth permanent magnet materials, its remanence, coercivity and the maximum energy product higher than the former, non-friable, have good mechanical properties, low alloy density, magnetic components in favor of light , thin, small and ultra-miniaturization. Hengdian Dongyang City, Kim Dae-magnetic magnet failure and treatment plant --- phenomenon: multi-axis, leakage vehicles, magnetic steel indicator light phenomenon. Reasons: 1) interference and cause. 2) is caused by outdoor rail high current, high-voltage power line near substations, locomotives; "prohibit double bow" section magnet manufacturers address, will produce great interference locomotive commutation. 3) large interfering signals may cause the device to be locked magnets Which is good, the whole column leaking car phenomenon. Find and treatment methods: 1) CANTON or Guanghan Kefeng systems may be appropriate to increase the threshold voltage, the system Jaco adjustable input resistance and gate resistance. 2) Check the device and the rail side piping magnets embedded within this distance cable insulation is good. 3) Check the device and the inner rail side pipes embedded magnet cable shield is grounded; check the equipment itself is grounded magnet suppliers, the ground is good, if the equipment is not properly grounded, but will cause greater interference, temporarily grounding choose , and other ground handling and re-grounded. Magnet manufacturer, Wenzhou magnet, Kim Dae-magnetic factory trusted by Kim Hengdian magnetic plant. Hengdian Dongyang City, Kim Dae-magnetic Factory (www.jjdct.cn) strong, credible, Zhejiang Jinhua electronics, electrical products manufacturing equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Kim Dae-magnetic plant into the brilliant and you work for a better future!
