The invention discloses an electromagnetic magnetic rail
brake and a control method of the electromagnetic magnetic rail
brake. 2n electromagnets distributed in the vertical direction of a rail at equal intervals are arranged between the rail and a vertical beam, each
electromagnet respectively consists of a
magnetic core and at least two groups of excitation coils, the excitation coils are arranged in the axial direction of the
magnetic core and have the same winding
modes, the adjacent two electromagnets sequentially form one pair, a closed work magnetic path is formed by each pair of electromagnets, the vertical beam, the rail, and air gaps between each pair of electromagnets and the rail, all of the closed work magnetic paths have loop directions in sequential arrangement at intervals in opposite directions, in addition, axial lines of the closed work magnetic paths are respectively vertical to the vertical direction of the rail, all excitation coils in one closed work magnetic path are respectively connected with the same excitation module, all of the excitation modules are respectively connected with an
electronic control unit (ECU), two sets of power supply circuits with a storage battery connected in parallel with a
contact network are adopted for control, high braking reliability of high-speed rail vehicles during the emergency braking can be ensured, and the rail vehicles can reliably stop through consuming little energy during the parking.
