Eddy current, electromagnetic damping, the difference electromagnetic drive Electromagnetic driving the opposite is the use of electromagnetic induction principle is that the electrical energy into mechanical energy (such as the magnetic levitation train) electromagnetic damping is the use of electromagnetic induction principle is that the mechanical energy into electrical energy and then make it as soon as possible discontinuities or balance The vortex is because ring induction electromagnetic induction current generated in the bulk conductor two is available after the Lenz theorem interpretation (stop magnetic flux change) Dongguan Jincheng Industrial Co., Ltd. is a research and development, manufacturing, sale of tension control, magnetic damper, as one of the professional manufacturers, the main production: tension device series, magnetic damper series, tension device, magnetic damper, magnetic damper damper, damper, and other goods.
