However, in the former case, the selection of the angle at which the permanent magnet is placed on the rotor, and the contact, disconnection, and polarity of the electromagnet to prevent the reaction when the permanent magnet enters the magnetic field of the electromagnet during rotation and to energize it. Synchronous control such as inversion is difficult, and there are many difficult aspects in implementation.
Further, in the latter case, when rotating, the structure for avoiding the reaction when the permanent magnet enters the magnetic field of the circumscribed permanent magnet and energizing it is "one semi-peripheral circular portion along the rotation axis of the rotor" The magnetic poles are equidistant in the circumferential direction, provided with a permanent magnet arranged so as to have a certain angle in a state of being directed radially outward, and a balancer made of a non-magnetic material on the other semi-peripheral edge, It is a magnetic rotating device comprising a rotating body fixed to a rotating shaft "
“An external permanent magnet is arranged in the vicinity of the rotating body so as to be movable in the direction of the rotating body and in the radial direction of the rotating body so as to have the same magnetic pole as the permanent magnet. When the leading permanent magnet enters the external permanent magnet, the side of the rotating body protrudes from the balancer portion to the range of the front half with respect to the rotational direction of the permanent magnet so that the distance from the external permanent magnet is increased. There are drawings, as examples,
The external permanent magnet always slides on the outer peripheral edge of the rotating body by the pressing force, and there are problems with resistance during rotation and durability of the sliding part of the permanent magnet due to wear. Even though the reaction can be avoided, the reactions of the many permanent magnets that follow cannot be avoided, and the problem is how much this part can contribute to rotation by inertial force and biasing force.
Further, the balancer portion extending over the latter half of the circumference contributes to the balance of the rotating body, but has no biasing force.
