１．補助ヨーク２にて磁路が構成されている。As shown in Fig. 3, the magnet motor has a frame 1
and auxiliary yoke 2. The bracket 3 constitutes the outer shell. A magnetic pole magnet 4 is fixed to the frame 1. Iron core part 6 of amateur 5 and magnet 4. Frame 1. The auxiliary yoke 2 constitutes a magnetic path.
フレーム１はプレス絞り加工品で作られており、ヨーク
部分の肉厚を増すことが困難であるため、フレーム１の
外周に補助ヨーク２が取付けられる。The frame 1 is made of a press-drawn product, and since it is difficult to increase the thickness of the yoke portion, an auxiliary yoke 2 is attached to the outer periphery of the frame 1.

原因となっていた。Problems to be Solved by the Invention In such a conventional auxiliary yoke 3, in order to be attached to the outer periphery of the frame 2, the auxiliary yoke 3 has the shape of a thin plate wound cylinder or a C-shaped wound cylinder, and completely surrounds the outer periphery of the magnetic pole. Therefore, the magnetic flux passes through the frame 2 and the auxiliary yoke 3. Part of the magnetic flux from the center of the magnetic pole becomes leakage flux, causing iron loss.
本発明は上記課題を解決するもので、マグネットモータ
の鉄損を低減することを目的としている。The present invention solves the above problems and aims to reduce core loss of a magnet motor.

。フレーム１１は鋼板をプレス加工して作られている。EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2. As shown in the figure, the magnet motor consists of a frame 11, a magnet 14, and an armature 15.
A magnetic path is constituted by the iron core portion 161m and the auxiliary yoke 12. The frame 11 is made by pressing a steel plate.

によって磁束は補助ヨーク１２に流れ有効に働く分と漏
れ磁束になる分とになる。Due to deep drawing, it is thin and magnetically saturated. An auxiliary yoke 12 is attached to lower the magnetic flux density. A slit 12a is provided in the auxiliary yoke 12. The socket 12a and the opening of the auxiliary yoke 12 are attached to match the center positions of the N and S poles of the magnet 14, respectively. The magnetic flux generated from the magnet 14 passes through the frame 11 and reaches the auxiliary yoke 12. There is magnetic leakage from the auxiliary yoke 12 to the outer periphery. The magnetic flux from the magnet 14 causes the frame 11. Auxiliary yoke 12
Iron loss occurs. Slit portion 12a of auxiliary yoke 12
As a result, the magnetic flux flows into the auxiliary yoke 12 and acts effectively, and the other becomes leakage magnetic flux.
濁れ磁束になる分での鉄損をスリット部１２ａによって
減少させることが可能となる。The slit portion 12a makes it possible to reduce the iron loss caused by the turbid magnetic flux.
このように本発明の実施例の補助ヨークによれば、漏れ
磁束による鉄損を低減でき、主磁束分は減少させずに得
られるものである。As described above, according to the auxiliary yoke of the embodiment of the present invention, iron loss due to leakage magnetic flux can be reduced without reducing the main magnetic flux.
