The utility model discloses a short stroke DC electromagnetic brake, including spring adjusting device, the clearance adjusting device and the base, which comprises the drive mechanism and the electromagnetic mechanism, including two groups of electromagnetic mechanism for the electromagnetic coil, were installed in the stator, stator and a hinge; the transmission mechanism the two group includes brake shoe, brake short arm, long brake arm and the link, two sets of brake shoe which are respectively fixedly connected with the long arm and short arm brake brake, the brake arm of the central end of long and short brake arms are respectively connected with the base; one end of the connecting rod is connected to the brake arm length, free end the activities and the other end of the short arm connected with the brake. The electromagnetic coil is energized, the moving core is attracted and deflected to the left, the left brake shoe left brake wheel, while pulling the right brake away from the brake wheel, complete brake open; conversely, when power on the brake spring to push the brake arm long turn to the right, to realize the brake. The utility model has the advantages of simple structure and quick action.
