  Hereinafter, the permanent magnet rotation device 100 according to Embodiment-1 of the present invention will be described with reference to the drawings as appropriate.

  As shown in FIGS. 1 and 2, the permanent magnet rotation device 100 according to the present embodiment has N poles in the rotation direction at the outer diameter portion of a disc-shaped rotor body 1 that is a nonmagnetic material fixed to a shaft 21. The rotor magnets 11, which are a plurality of permanent magnets in which the S poles are alternately magnetized, are grouped together, and the rotor magnets 11 are fixedly attached at a rotor magnet mounting pitch θp.

  In this embodiment, the rotor magnet group setting angle θ1 is 90 °, the rotor magnet group mounting angle θa is θa> θ1, and there are seven set rotor magnets 11 in one group, and the rotation direction of the group Before and after, one rotor magnet 11 is arranged, and a total of nine are fixed. Here, the number of rotor magnet groups n1 ≧ 2 or more with respect to a circle of 360 °, the division number N = 2 · n1, and the rotor magnet group is arranged in a blank portion and a rotor without the rotor magnet 11. Magnet groups are arranged alternately.

  The shaft 21 is rotatably supported by bearings 22 arranged on both sides of the frame 100. Further, a disc-shaped rotating stator body 3 which is a non-magnetic material is fixed to a shaft 41 and is rotatably supported by bearings 42 arranged on both sides of the frame 10.

  Next, in this embodiment, two rotating stator magnets 31 are fixed to the rotating stator body 3 at equal intervals with the north pole magnetized in the radial direction from the center of the rotating stator body 3 at the same interval. The stator magnet mounting angle θ2 = 180 °.

  Here, as shown in FIG. 1, the large gear 25 is fixed to the shaft 21 on one side of the rotor body 1, and the small gear 45 that meshes with the large gear 25 is disposed on one side of the rotating stator body 3. 42 is fixed.

  Of the rare earth permanent magnets, neodymium (Nd) is preferably used for the rotor magnet 11 and the rotating stator magnet 31 because of its strong magnetic force.

  In this embodiment, the rotor magnet 11 is a square magnet. However, if the magnetization direction is the same, a cylindrical magnet can be used. Similarly, the rotary stator magnet 31 is a cylindrical magnet. However, if the magnetization direction is the same, a square magnet can be used, and if the magnetization direction is the same, other shapes can be used.

  FIG. 3 shows the principle operation of the permanent magnet rotating device according to the present invention. When the magnet 82 fixed to the fixed body 81 and the plurality of magnets 72 fixed to the moving body 71 are opposed to each other while maintaining the air gap S, the moving body 71 is caused by the magnetic action between the N pole of the magnet 82 and the magnet 72. It has been confirmed by experiments that the magnet 72 moves to the N pole side, that is, moves to the left. The moving distance stops at a point where the magnet 72 and the magnet 82 face each other with the moving body 71 at the right end. Here, if the magnet 82 is turned and the S pole is opposed to the magnet 72, the moving body 71 moves to the S pole side, that is, moves to the right.

  Next, when the magnet thickness of the magnet 72 is a, the magnet gap Cs = (0.5 to 0.8) a is preferable, and the length d ′ of the magnet 82 is preferably d ′ ≧ a to a + Cs.

  4 and 5 show the relationship between the rotor magnet 11 and the rotating stator magnet 31, and there is a gap S between the rotor magnet 11 and the rotating stator magnet 31 when they are close to each other. When the magnet thickness is a, the magnet gap Cs = (0.5 to 0.8) a is preferable, the rotating stator magnet diameter d ≧ a to a + Cs is desirable, b is the magnet width, and θp is the rotor magnet mounting. Is the pitch. Here, due to the magnetic force action of the rotating stator magnet 31 facing the rotor magnet 11, the large gear 25 on the rotor body 1 side and the small gear 45 on the rotating stator body 3 side are engaged with each other as shown in FIG. The rotor body 1 rotates to the left and the rotating stator body 3 rotates to the right.

  Here, in FIG. 5, if the north pole of the rotating stator magnet 31 is the south pole, the rotating direction of the rotating body 1 is clockwise.

  FIG. 6 is an explanatory view showing the relationship between the rotor magnet 11 and the rotary stator magnet 31 according to the embodiment-1 for carrying out the present invention. For convenience of explanation, nine of the rotor magnets 11a to 11i and 11j Two groups of ˜11r are arranged on the rotor body 1. The rotation angle of the rotor body 1 is 0 °, and is at a point where the rotor magnet 11b is arranged at the 0 ° position. Here, the rotor magnets 11a to 11i and 11j to 11r are arranged at equal intervals at the rotor magnet mounting pitch θp. Further, two of the rotating stator magnets 31a and 31b are arranged on the rotating stator body 3, and the rotation stator magnet 31a and the rotor magnet 11b will be described from the point where they face each other.

  In FIG. 6, the rotor body 1 is rotated to the N pole side of the rotor magnet 11a, that is, counterclockwise by the magnetic action of the rotating stator magnet 31a and the rotor magnets 11a to 11c. The rotating stator body 3 rotates clockwise by being accelerated by the gear mechanism. If the rotational force is expressed as large, small, and minute, the rotational force is “large”.

  Here, as shown in FIG. 6, in this embodiment, the rotor magnet group setting angle θ1 = 90 ° of the rotor magnet 11 on the rotor body 1 side, and two rotation fixings arranged on the rotating stator body 3 side. Since the rotation stator magnet mounting angle θ2 of the child magnet 31 is 180 °, the gear speed increase ratio i = 180/90 = 2. That is, when the rotor body 1 rotates 180 ° counterclockwise, the rotating stator body 3 rotates 360 ° clockwise.

  Further, the number of rotating stator magnets n2 = 2 is preferable. However, depending on the relationship between the rotor magnet mounting diameter D1 and the rotating stator magnet mounting diameter D2, n2 = 3 or 4 and the gear speed increase ratio i. It can be configured if it is ≦ 1 or more.

  Here, when the rotor magnet group setting angle θ1 = 60 °, the number of rotating stator magnets n2 = 2, and the rotating stator magnet mounting angle θ2 = 180 °, the gear speed increase ratio i = 180/60 = 3. Just do it.

  Further, when the rotor magnet group setting angle θ1 = 60 °, the number of rotating stator magnets n2 = 3, and the rotating stator magnet mounting angle θ2 = 120 °, the gear speed increasing ratio i = 120/60 = 2. It ’s fine.

  FIG. 8 shows a state in which the rotation angle of the rotor magnet 11b is rotated 45 ° counterclockwise, and the rotary stator magnets 31a and 31b are in an upright state in FIG. However, due to the inertial force of the rotor body 1 and the like according to FIGS. 6 and 7, the rotor body 1 rotates to the left and the rotating stator body 3 continues to rotate to the right.

  FIG. 9 shows a state in which the rotation angle of the rotor magnet 11b is rotated by 70 ° counterclockwise. The rotor body 1 is turned to the left rotor by the magnetic action of the rotary stator magnet 31b and the rotor magnets 11g and 11h. The rotating stator body 3 increases in speed and rotates to the right, and its rotational force is “small”.

  FIG. 10 shows a state in which the rotation angle of the rotor magnet 11b is rotated 90 ° counterclockwise, and the rotor body 1 rotates counterclockwise by the magnetic action of the rotating stator magnet 31b and the rotor magnets 11g to 11i. The rotating stator body 3 is increased in speed and rotated to the right, and its rotational force is “large”.

However, the rotor body 1 rotates to the left by the inertial force of the rotor body 1 and the like according to FIGS. 10 and 11, and the rotating stator body 3 continues to rotate to the right.

  FIG. 13 shows a state where the rotation angle of the rotor magnet 11b is rotated by 150 ° counterclockwise, and the rotor body 1 rotates counterclockwise by the magnetic action of the rotating stator magnet 31a and the rotor magnets 11j and 11k.
