Claims

[Scope of utility model registration request]

A yoke in which an electromagnetic coil is installed is formed into a cylindrical shape with a stepped portion where the inner circumference is lower than the outer circumference, and a cylindrical adapter made of a non-magnetic material is fitted into the inner hole of this yoke. A rotor whose inner member is made of a non-magnetic material and whose outer member is made of a magnetic material is placed on the upper end of a rotating shaft that is supported via a bearing, and the lower end surface of the outer member is opposed to the upper end surface of the inner peripheral part of the yoke. The rotary body and the yoke are fixed in this state, and the rotary body and the yoke are covered with a cover made of a magnetic material, and an annular gap is formed above and below the outer member of the rotary body, and this annular gap is filled with magnetic powder. An electromagnetic powder brake characterized in that an upper end surface of the adapter is formed higher than a bottom surface of the lower annular gap.
