Brake magnetic pole structure for linear eddy current brake device

The invention discloses a brake magnetic pole structure for a linear eddy current brake device. The transformer comprises an iron core, an insulating layer, a coil, a supporting layer, a fixing ribbon, a binding post and a packaging layer, a plurality of grooves in the axial direction are formed in the periphery of the iron core at intervals, the insulating layer wraps the periphery of the iron core, the fixing ribbon is fixed in the grooves of the iron core, and the coil is wound around the periphery of the insulating layer and used for generating magnetomotive force after being powered on; and the coil is tightened by the fixing ribbons, and the coil, the insulating layer and the supporting layer are fixed together and kept in the periphery of the iron core. According to the invention, the rectangular grooves in the periphery of the iron core are used for placing and fixing the ribbon, so that the aluminum flat wire has more winding space, the groove fullness rate is improved, and the ampere-turns number is
