Embodiment 1
Hereinafter, a permanent magnet motor 100 according to an embodiment of the present invention will be described with reference to the drawings as appropriate.

  As shown in FIGS. 1 and 2, the permanent magnet motor 100 according to the present embodiment includes a plurality of magnets magnetized in the rotational direction on the outer periphery of a disc-like rotor 1 that is a nonmagnetic material fixed to a shaft 21. The rotor magnets 11 which are permanent magnets are arranged at equal intervals. In this embodiment, there are four rotor magnets 11.

  The shaft 21 is rotatably supported by bearings 22 disposed on the front and rear surfaces of the frame 10.

  As shown in FIG. 2, the stator 3a, 3b, which is a semi-cylindrical non-magnetic member divided into two along the rotor center line, has a V-shaped rotor magnet 11 from both sides as shown in FIG. A stator magnet 31, which is a plurality of permanent magnets magnetized radially from the center of the rotor 1, is radially fixed to the inner periphery of the stators 3a and 3b so as to be sandwiched between them. In this embodiment, as shown in FIG. 2, the case of 9 × 2 surfaces is shown, the mounting angle θ1 of the rotor magnet 11 is 90 °, the mounting angle θ2 of the stator magnet 31 is 40 °, and the rotor magnet length The length a is smaller than the stator magnet mounting pitch P, but it can be configured to be equal or larger.

  As the rotor magnet 11 and the stator magnet 31, neodymium (Nd) having an isotropic magnetic force among rare earth permanent magnets is preferably used because of its strong magnetic force, but it can also be a ferrite or samaba magnet.

  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, although the stator magnet 31 is a cylindrical magnet, a square magnet can be used as long as the magnetization directions are the same.
