Claims

[Scope of utility model registration request]

A disk-shaped rotor made of a hysteresis material is fitted onto a rotating shaft and supported to rotate freely, an annular core is provided that faces the rotor through an axial gap, and an axial gap end face of the core is provided. In an axial gap type rotating electric machine, in which coils are housed in slots radially provided to form a stator, and the stator is fastened to the frame via a flange at the bottom, a small gap is formed at the end face of the axial gap of the iron core. A plurality of radial slits are formed in an annular disc made of a non-magnetic and good conductor material that is separated from and covered with, and the core and coil are covered with an outer frame consisting of an inner cylinder part and an outer cylinder part that are integrated with the annular disc. An axial gap type rotary electric machine characterized by:゛
