間することを特徴とする、電磁ブレーキ。 It has an annular field core that is a fixed member in which an excitation coil is installed, and an annular groove into which an axially protruding annular portion of the field core is inserted,
A first movable disk made of a magnetic material is supported by the field core so as to be movable only in the axial direction; a second movable disk made of a magnetic material that is supported in a permissible manner, and a magnetic material that is disposed with a slight gap between the first and second movable disks and is integrally fixed to the braked member. Equipped with a fixed disk made of
The magnetic flux generated by the excitation coil causes the first and second movable disks to pinch the fixed disk against the restoring force of the elastic member, while the disappearance of the magnetic flux causes the fixed disk to move away from the fixed disk. Due to the restoring force of the elastic member, the first
and an electromagnetic brake, characterized in that the second movable disk is spaced apart from each other with the gap.
