分を示す。Fig. 1 is a longitudinal cross-sectional view of a portion of a conventional disc-type eddy current brake, Fig. 2 is a side view taken from line ■-■ in Fig. 1,
Figures 3a and 3b are diagrams showing the magnetic pole arrangement, both are cross-sectional views taken along the line ■-■ in Figure 2, Figure 4 is a diagram showing the braking torque characteristics according to the magnetic pole arrangement, and Figure 5 is the FIG. 1 is a partial vertical sectional view showing an embodiment of the invention. In the figure, 1 is a rotating shaft, 2A is a disk, 3 is a magnetic pole, 4 is an excitation winding, 5 is a magnetic pole holding frame, 6 is an annular slot, and 7 is a magnetic resistance adjuster. Note that the same reference numerals in the figures indicate the same or corresponding parts.

Claims

[Scope of utility model registration request]

(1) In a disc-shaped eddy current brake that has a disc, a plurality of magnetic poles that are oppositely polarized while sandwiching the disc, and a magnetic pole holding frame that holds each magnetic pole on both sides of the disc, the outer circumferential surface of the disc is 1. A disk-shaped eddy current brake, characterized in that it has an annular slot for adjusting magnetic resistance and is equipped with a magnetic or non-magnetic magnetic resistance adjuster that can be inserted into the annular slot in a non-contact manner.

(2) The disc-shaped eddy current brake according to claim 1, which is a utility model, in which an annular slot is provided in the center of the outer peripheral surface of the disc in the thickness direction.

(3) The disk-shaped eddy current brake according to claim 1 or 2, wherein the magnetic resistance adjuster is a magnetic plate having a length in the circumferential direction of the disk that spans all magnetic poles.
