摘要 |
Projections 30 of a commutator unit 23 formed on the radial line of slit center positions of commutator piece 26 arranged radially are inserted into through holes 22 made on the center axes of salient poles 19 arranged radially in an armature core 15 and a rotator with high position accuracy of center points with respect to the salient poles 19 is formed. A projection tip face 30c is positioned on a shaft 14 to accurate predetermined dimension A from the rear end of the shaft, whereby accuracy of play gap D can be improved. The commutator unit 23 is reinforced with the projections 30 and wrong form dimensions made due to heat deformation at the soldering treatment time can be prevented.
