。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a hybrid stepping motor,
More specifically, the present invention relates to a hybrid stepping motor in which a cylindrical superconducting material is installed on the side surface of a cylindrical soft magnetic material constituting a rotor, thereby increasing the efficiency of the magnetic flux of the magnet.

いる。A perspective view of the rotor in a conventional hybrid stepping motor is shown in Fig. 3, and a structural diagram of the flow of magnetic flux is shown in Fig. 4. It consists of a rotor formed by sandwiching a permanent magnet 12 between the stator core 15 and a stator core 15 made of laminated silicon steel plates with similar gear cutting on the surface facing the rotor, and an excitation coil 17 wound around the stator core 15. .
近年、ステッピングモーターは、ハードディスク及びフ
ロッピーディスクなど多量に使用され、年々小型化軽量
化要求が強くなってきた。In recent years, stepping motors have been used in large quantities in hard disks, floppy disks, and the like, and demands for smaller size and lighter weight have become stronger year by year.
しかしながら従来の技術では、ハイブリッド形ステッピ
ングモーターの電気性能をあげようとするとローターに
使用しているマグネットの性能をあげる必要があった。However, with conventional technology, in order to improve the electrical performance of a hybrid stepping motor, it was necessary to improve the performance of the magnet used in the rotor.

トの性能を上げるとコスト高になってしまう。However, on the other hand, there was a major drawback: magnetic flux leaked from the rotor, which had an adverse effect on the peripheral equipment used, and the material of the flange had to be changed and demagnetized in order to suppress the leaked magnetic flux. In addition, increasing the performance of the magnet increases the cost.

モーターができる。FIG. 1 shows a perspective view of the rotor of the hybrid stepping motor of the present invention. It is composed of laminated disc-shaped silicon steel plates, and a superconducting material 14 is installed in a cylindrical shape on the side surface of the column-shaped soft magnetic body. Figure 2 is a structural diagram for viewing the flow of magnetic flux.As shown in Figure 0, when the rotor magnet is magnetized, the superconducting material installed in the rotor has a magnetic shielding effect. All magnetic flux passes through the teeth of the rotor, avoiding the superconducting material, forming a magnetic circuit. Not only is this similar to the magnetic circuit of a conventional rotor, but because the magnetic shielding effect of the superconducting material is high, there is no leakage of magnetic flux compared to conventional motors, making it possible to create a highly efficient motor.

多さに比べると格段に高性能な物が製作できる。Methods for installing the cylindrical superconducting material include a method of fixing the cylindrical superconducting material obtained by a sintering method to a soft magnetic material using an adhesive, a method of etching a film formed by sputtering, and a method of etching a film formed by sputtering. A method of mixing thermoreversible resin and superconductor powder and then forming it into a columnar shape by screen printing or the like is considered, and either method can produce a product with much higher performance than the conventional method, which has a large amount of magnetic flux leakage.
