である。[Means for Solving the Problems and Their Effects] The electric machine of the present invention has permanent magnets arranged tangentially between the pole terminals, and these pole terminals have magnets on the surfaces in contact with the permanent magnets. A groove is formed, and wedge members are inserted into the groove, the length of these wedge members is longer than the above-mentioned terminal, and the ends of these wedge members are connected to each other with a non-magnetic material and are connected to the shaft of the electric machine. It is installed.

本発明によれば、永久磁石の径方向の長さが長くなり、
磁束密度が高くなる。また、極ターミナルの内側端部は
軸への磁束の漏洩が小さくなるように形成できる。According to the present invention, the radial length of the permanent magnet is increased,
Magnetic flux density increases. Additionally, the inner end of the pole terminal can be formed to reduce leakage of magnetic flux to the shaft.

［実施例］ 以下図を参照して本発明の詳細な説明する。[Example] The present invention will be described in detail below with reference to the drawings.

Further, as shown in FIG. 2, the ends of the wedge members 2 are mechanically coupled to each other by a non-magnetic member 3, and these are attached to a shaft 4 of the electric machine.

Therefore, the increased length of this permanent magnet increases the magnetic flux density and improves the performance of this electric machine.

また、このような構成によってこの電機の軸への磁束の
漏洩が減少し、磁石の効率が向上する。Additionally, such a configuration reduces leakage of magnetic flux to the shaft of this electric machine, improving the efficiency of the magnet.
