Claims

[Scope of utility model registration request]

A brake plate is provided to be slidable in the axial direction together with the movable core of the electromagnet, and a keep plate is provided with one end passing through the brake plate in the axial direction and fixed integrally with the movable core, and the other end of the keep plate is provided. was extended to near the position of the brake disc fixed to the rotating shaft, and a lining was placed in the area surrounded by the keep plate, brake plate, and brake disc at this extended part, so that braking was applied when no excitation was applied. In a product, a first lining and a second lining made of different materials are attached to both sides of a lining plate, and
The lining portion is configured such that the friction torque of the first lining on the brake plate side is smaller than the friction torque of the second lining on the brake disk side, and the lining portion is disposed in a free state. Electromagnetic brake device.
