。Generally, in this type of electric motor and generator, sparks are generated at the moment the commutator contacts the brush and at the moment the commutator separates from the brush. As a result, noise is generated or the brush burns out and wears out, so as a means to prevent this, reduce the number of turns in the armature to reduce the induced voltage and suppress the generation of sparks.9 Or select the material of the brush. Therefore, methods were adopted to reduce its consumption. An object of the present invention is to provide a rectifying device for a motor and a generator that can prevent the generation of sparks by a new means in place of the conventional methods.

花の発生を防止することが可能となる。In the rectifier of the present invention, the relationship between the commutator and the brush is such that the rate of change in the area of the contact surface between the brush and the commutator in the direction of rotation of the commutator is gradually increased or decreased. The goal is to make it thicker and gradually make it smaller. That is, the contact resistance of the brush with respect to the commutator can be gradually decreased or increased, and the contact resistance of the brush can be gradually decreased and then gradually increased again. In this way, the contact resistance at the moment when the commutator comes into contact with the brush and the moment when the commutator separates from the brush is small, so that there is no sudden change in current, and it is possible to prevent the generation of sparks.

流子片との接触面積Ｓは次式で表わすことができる。Embodiments of the present invention will be described with reference to the drawings. In FIGS. 1 and 2, 2 is a rotating shaft, and 2 is a commutator, which is composed of commutator pieces ga, 9n%2C...2n. 8 is a cross-sectional hairstyle brush, and 4 is a contact surface with the commutator piece. Figure 8 shows the contact surface 4 between the commutator piece and the brush.
It shows. The contact area S between the brush and the commutator piece when the commutator rotates in the direction of the arrow and the contact between the brush and the commutator piece reaches point X from point a can be expressed by the following equation.
８＝Ａ、Ｚ’十Ｂχ十Ｃ

し、ｂｅ間においては同様に減少する。8 = A, Z' 10 B χ 0 C So, A, B, and C are constants determined by the shape of the brush, and S increases in proportion to the square of X between a and b, and increases between be and decreases as well.

に基づくものである。In the present invention, the reason why the rate of change in the area of the contact surface between the brush and the commutator is set to 057 to 3.47 or -057 to -3.47 is because the angles α and β of the rhombic brush are 80° to 120°. This is based on the practical range of the diamond-shaped brush shape.

たがって発明の目的を達成する効果を有する。[Effect of the invention] In the conventional rectifying device, as shown in FIGS. 4 and 5, the contact surface 4 between the brush and the commutator is rectangular.
The rate of change in the contact area was always constant and sparks were generated at the moment the commutator came into contact with or separated from the brush, but in the present invention, the above-mentioned configuration reduces the contact resistance when the commutator comes into contact with or separates from the brush. By increasing the amount of water, sparks are prevented from being generated, thereby preventing noise and brush burnout. Therefore, it has the effect of achieving the purpose of the invention.
