Claims

[Scope of utility model registration request]

An outer pole that is movable in the axial direction and fixed in the torsional direction via a biasing member, is provided with a friction plate on the front edge, and includes an excitation coil, an inner pole, and a permanent magnet on the attached body. and a magnet portion having an opening in the center, a shaft extending through the opening of the magnet portion and the object to be attached, and the shaft being fixed to the shaft with the shaft passing through the center portion. and an armature portion having an armature plate provided at a small distance from the friction plate at a portion of the magnet portion facing the friction plate, and when the excitation coil is not energized, the permanent magnet is The magnet portion is moved in a direction away from the mounting body against the biasing force of the biasing member to bring the friction plate and the armature plate into contact with each other to brake the shaft, and when the excitation coil is excited, The magnetic force generated by this excitation coil in the opposite direction to the permanent magnet releases the contact and releases the braking of the shaft, and further penetrates the symmetrical position of the flange portion of the outer pole to attach the pair of attachments. A bolt is fixed to the object to be attached, and the leg of a manual opening handle having a pair of legs split into a forked shape is supported by the mounting bolt from a grip located at the center, and when the excitation coil is not energized, By operating a grip portion of a manual release handle, the outer pole is moved in the axial direction against the elastic force of the biasing member, and the contact between the friction plate and the armature plate is released. An electromagnetic brake characterized by being equipped with a manual release device for releasing the brake.
