COMMUTATOR
Document Type and Number:
Japanese Patent JP3343434
Kind Code:
B2
Abstract:
PURPOSE: To provide a commutator wherein there is no riser and no fusing nor soldering of a terminal of a winding is necessary and which can be easily connected to a coil at the winding terminal.
CONSTITUTION: This is a commutator S which is made by assemblying a segment 20 having no riser to a base 10. The base 10 has a plurality of arm sections 12 which are extended from one end of a cylindrical section 11. The segment 20 has a plurality of sharp, small projections 15 at its one face which faces the arm sections 12 when it is mounted on the base 10. A recess 12b is formed in the cylindrical section 11 at the arm section 12 side. The segment 20 mounted in the recess 12b and the arm section 12 form a winding supporting recess 14 which gets narrow as it comes near a basic end of the arm section. And a winding is fit in a narrow section of the winding supporting recess 14 which is smaller than the diameter of the winding 17 and a film of the winding is destroyed by the small projections 15 and thereby the winding is connected to the commutator.
