のローター。 A rotor is fitted to one end of the rotating shaft, and a support ring with a plurality of permanent magnets surrounding it so that the polarities of adjacent magnets are opposite to each other is attached to the rotor in the axial direction of the rotating shaft. In a speed reducer, the length of which can be freely moved back and forth from a position where the pole faces are completely magnetically opposed to the rotor to a position where they are completely separated from the rotor when the pole surface is empty is the rotor's outer circumferential surface, which has a large number of cooling fins circumferentially arranged. A rotor for an eddy current speed reducer with a cylindrical wall that has a hollow outer circumferential surface and a thin wall overall.
