いる。 An embodiment of the present invention will be described below with reference to FIG. A support shaft 3 is fixed to the inside of one of the two base plates 1 and 2 arranged in parallel.
A magnet mounting shaft portion 3a is formed on the support shaft 3 on the ground plate 1 side, and a vortex disk mounting shaft portion 3b is formed protruding from the magnet mounting shaft portion 3a toward the ground plate 2 side. An inner diameter portion of a magnetic induction plate 5 to which a permanent magnet 4 is fixed is fixed to the magnet mounting shaft portion 3a. A non-magnetic pipe shaft 7 to which an eddy current disc 6 is fixed is rotatably inserted into the eddy current disc mounting shaft 3b.
are vertically positioned by a collar 8 fixed to the tip of the swirl disk mounting shaft portion 3b. Further, a gear portion is provided on the outer periphery of the vortex disk 6,
A gear 9 rotated by a drive source (not shown) meshes with this gear portion. A permanent magnet 10 is disposed on the other base plate 2 to face the permanent magnet 4.
A magnetic induction plate 11 to which is fixed is rotatably inserted and fixed to the base plate 2 by engaging a fixing spring 12 such as a speed nut with a portion projecting outward from the base plate 2. In addition, a groove 11 for engaging a screwdriver etc. is provided at the outer end of the main plate 2 of the magnetic induction plate 11.
a is formed. Further, the two permanent magnets 4 and 10 are multipole magnetized on opposing surfaces, for example, as shown in FIG. 2, so that the NS poles are arranged in the same manner.

で回転する。 Now, the opposing magnetic poles of the permanent magnets 4 and 10 that are arranged opposite each other are set so that the different poles N and S are opposed to each other as shown in FIG. 1, and a drive source (not shown) is started to rotate the gear 9. As a result, the eddy current disk 6 rotates, and an eddy current is generated in the eddy current disk 6 by the magnetic flux of the permanent magnets 4 and 10, and a braking force is applied to the eddy current disk 6. It is controlled and rotates at a constant speed.

く、渦流円板６は制動されなく高速で回転する。 Next, a screwdriver is engaged with the groove 11a of the magnetic guide plate 11 to rotate the magnetic guide plate 11. This causes the permanent magnet 10 to also rotate. When the opposing poles of the two permanent magnets 4 and 10 are adjusted so that they are the same, that is, N and N, and S and S, the magnetic fluxes of the permanent magnets 4 and 10 are repelled, so that the eddy current disk 6 Even when the eddy current disk 6 rotates, almost no eddy current is generated in the eddy current disk 6, and the eddy current disk 6 rotates at high speed without being braked.

The rotational speed of the vortex disk 6 can be freely controlled to a desired rotational speed. In addition, permanent magnets 4 are placed on both sides of the vortex disk 6.

Although the permanent magnets 4 and 10 are provided so as to be rotationally adjustable, both permanent magnets 4 and 10 may be provided so as to be rotationally adjustable. Alternatively, the pipe shaft 7 may be formed long so as to protrude outside the base plate 2, and a pointer or the like may be fixed to this protrusion.

The permanent magnet is rotatably arranged concentrically with the eddy current disk, so
The rotational speed of the vortex disk can be easily fine-tuned to a desired rotational speed. Further, the rotational speed of the vortex disk can be freely adjusted within a range of low speed or higher than 0, and the adjustment range of the rotational speed of the vortex disk is very wide. In addition, since the permanent magnet is adjusted by rotating concentrically with the eddy current disk, the distance from the eddy current disk is always constant, and the magnet can be made thin and compact. Moreover, since the structure is extremely simplified, it can be made at low cost.
