摘要： A fixing structure of the present invention is capable of fixing permanent magnets to an internal peripheral surface of a cylindrical yoke in a short time without producing a positional deviation. The fixing structure has magnet receiving pieces which are projected on the internal peripheral surface of an internal cylinder, and magnet holders each having elastically deformable magnet pressure pieces formed therein, so that permanent magnets are respectively held between the elastically deformed magnet pressure pieces and the magnet receiving pieces and pressed against the side of the magnet receiving pieces in a normal direction due to the elastic restoring force on the magnet pressure pieces. The permanent magnets can thus be integrally fixed to the internal peripheral surface of the internal cylinder.

摘要： A method which permits easy fusion of commutator risers to armature coils of an electric motor. When there are 20 risers, for example, 10 through-holes are formed in the boss portion of the armature core of the motor, each through-hole being so sized that the back surfaces of two adjacent risers are exposed through each through-hole. Sub-electrodes are inserted into the through-holes such that each sub-electrode supports the back side of the two risers exposed through the through-hole which receives this sub-electrode. First and second main electrodes are so arranged that the first electrode contacts with the first riser of the first riser group exposed through the first through-hole while the second main electrode contacts the second riser of the sixth riser group exposed through the sixth through-hole. After conducting fusing on these risers, the main electrodes are shifted into contact with the risers which are the second as counted from the risers which have just been fused, and fusion is conducted on these risers. This operation is repeated until all the risers are fused.
