涡流式的钢轨制动由于能够在钢轨与车辆(车轮)间直接产生制动力,所以,可以不依赖于车轮与钢轨间的粘着而产生制动作用。而以往的直流励磁式制动还存在需要确保断电时的励磁电源和制动时钢轨升温较高等问题。因此,日本铁道综合技术研究所将无需电源的线性电机型钢轨制动列为开发目标。该制动方式是
The eddy-current rail brake can generate a braking force directly between the rail and the vehicle (wheel), so that the brake can be applied independently of the adhesion between the wheel and the rail. In the past, DC excitation braking still had some problems such as the need to ensure the excitation power when the power was cut off and the rail temperature rise during braking. Therefore, the Japan Railway Institute of integrated technology will be no need to power linear motor type rail brake as a development goal. The braking method is
