電磁ドラムブレーキ。 A pair of cores are located inside a bottomed cylindrical case fixed to the equipment side and are rotatably supported near the outer periphery of the bottom plate of the case, and a hollow core is formed with the free end surfaces of each core facing each other. an excitation coil inserted into the case and fixed to the case; a bottomed cylindrical brake drum fixed to a rotating shaft in the center of the case and inscribed in the case; and a brake drum interposed between both cores. A pair of release pins protruding outward from the case in an electromagnetic drum brake comprising a braking spring that applies rotational force to the core in a direction to press an arc-shaped friction plate outside the core against an inner circumferential surface of the brake drum. is implanted in each of the cores, and a release lever formed in a semicircular arc shape with a diameter slightly larger than that of the case is attached to both leg ends so that the free end pressing portion contacts and separates from each of the release pins. An electromagnetic drum brake characterized in that it is rotatably supported on the outside of the cylindrical portion of the case.
