形電磁ブレーキ。A concentric ring-shaped inner pole and an outer pole are connected to each other on the back side, and a permanent magnet and a depolarizing electromagnetic coil are provided between the inner and outer poles. In a negative actuation type electromagnetic brake comprising an armature that can freely move away from the core in an axial direction and is attached to the side of a rotating member to be braked, the outer pole of the field core is connected to an outer pole that is spaced apart from each other in the front and back at an intermediate portion in the axial direction. It consists of a front pole part and a rear part of the outer pole, and an annular member made of a magnetic material that is movable in the axial direction and comes into contact with the other part is screwed into a male threaded part formed on one of the two parts. Negative action type electromagnetic brake.
