Definitions
- the present invention relates to a rotor of a brushed motor, particularly to a fixed part of a shaft and a commutator.
- the commutator has a structure in which a plurality of conductor parts integrally formed of resin are arranged in a cylindrical shape on the outer periphery, and the inner peripheral surface of the resin of the commutator is tapered. The diameter becomes larger as the diameter ⁇ of the intermediate portion is minimum and closer to the end portion.
- the commutator is made of resin, and the inner peripheral surface has a tapered shape in which the inner diameter is the smallest in the middle portion and increases toward both ends, and the shaft is press-fitted and fixed to the inner peripheral surface of the commutator.
- a motor is proposed.
- the inner diameter of the commutator is tapered so that initial breakage and creep breakage during press-fitting can be reduced and productivity can be improved.
- the problem to be solved by the present invention is to reduce the occurrence of contamination when the commutator is press-fitted into the knurling, thereby reducing the cause of defects due to contamination of the rotor and improving productivity.
- the present application includes a plurality of means for solving the above-mentioned problems.
