たりの出力も十分でないものが多かつた。 The above magnetic poles can be manufactured by machining as designed, but when melting non-magnetic materials, the magnetic poles are melted, so when the magnetic poles are cut after manufacturing is completed and the cross section is viewed, the lines of the magnetic poles are not straight lines but irregular curves. It's getting old. Fourth
The figure shows the shape as designed, and FIG. 5 is an example of this method. (1) is the magnetic pole and (2) is the non-magnetic material. That is, the designed shape cannot be maintained. Therefore, a rotating electric machine using a two-pole rotor manufactured in this way has an unstable magnetic flux distribution, which causes a lot of vibration, does not exhibit the electrical characteristics as designed, and does not have sufficient output per weight. There were many things that were not.
更に溶融盛金する作業時間が多くかかり保温に
注意をしないと割れが入ることがあつた。 Furthermore, it took a lot of time to melt and deposit the metal, and cracks could occur if care was not taken to keep it warm.
本発明はこのような事情に鑑みてなされたもの

電子ビーム溶接部１７にて接合する。 Two magnetic poles 1 manufactured in this way are installed on the axis A so as to face each other, and a central non-magnetic material 2a is manufactured to be embedded in the center of the space between both magnetic poles, and is embedded between both magnetic poles. The parts in contact with both magnetic poles are joined by an electron beam welding section 17.
