【実用新案登録請求の範囲】[Scope of utility model registration request] 筒状の磁性ヨークに永久磁石よりなるポールピースを固
着してなるものにおいて、上記永久磁石の径方向肉厚を
電機子反作用の増磁側に向うに従って薄くなる如く構成
し、上記永久磁石の厚さ減少量を補填する如く強磁性部
材を上記永久磁石と上記磁性ヨークとの間隙に装着する
ようにしたことを特徴とする直流機の界磁装置。A pole piece made of a permanent magnet is fixed to a cylindrical magnetic yoke, and the radial thickness of the permanent magnet is configured to become thinner toward the magnetization side of the armature reaction, and the thickness of the permanent magnet is A field device for a DC machine, characterized in that a ferromagnetic member is installed in a gap between the permanent magnet and the magnetic yoke so as to compensate for a decrease in the magnetic field.
