Claims

[Scope of utility model registration request]

A rotary body that has a built-in permanent magnet and is supported by a single axis and can rotate,
In a rotary display device comprising an electromagnet that cooperates with the permanent magnet to provide a rotational force to the rotating body, approximately 12
A rotating body with at least one permanent magnet painted in three colors at an angle of 0 degrees, 3 facing the surface of the rotating body.
The structure includes an electromagnet including two magnetic poles and a plurality of coils that selectively combine and excite the magnetic poles, and the pair of magnetic poles face each other at an angle of approximately 120 degrees with respect to the rotation axis of the rotating body. A rotary indicator characterized in that the other magnetic pole is disposed at approximately the same distance from the pair of magnetic poles.
