Problems solved by technology

[0004] In the existing commutator, due to the influence of factors such as environmental humidity and high temperature, short circuit or spark breakdown often occurs between the commutator segments, which affects the normal operation of the commutator and is not conducive to the development of related work. It may even cause serious consequences to the operation of the motor

Embodiment Construction

[0029] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0030] like figure 1 As shown, the improved commutator includes:

[0031] Body (not shown in the figure);

[0032] The commutation segments 10 are arranged in multiples and evenly distributed around the outer peripheral side of the body. An insulating sheet 20 is inserted between two adjacent commutating segments 10, and the insulating sheets 20 are closely attached to the two adjacent commutating segments 10 respectively. .

[0033] Further, there is only one insulating piece 20 between two adjacent commutating segments 10 and the insulating piece 20 is tightly connected to the corresponding commutating segment 10 .

[0034] In the existing commutator, due to the influence of factors such as environmental humidity and ...

Abstract

The invention provides an improved commutator, belongs to the mechanical technical field and solves the problem that an existing commutator is liable to be short-circuited. The improved commutator comprises a body and commutator segments, wherein the number of the commutator segments is more than one, the commutator segments are uniformly arranged around the peripheral side surface of body, an insulating sheet is inserted between two adjacent commutator segments, and each insulating sheet is tightly attached to two adjacent commutator segments. The improved commutator is prevented from being shorted and is prevented against an electric spark breakdown.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an improved commutator, in particular to an improved commutator with insulating sheets. Background technique [0002] The commutator, commonly known as the commutator, is a part of the DC permanent magnet series motor in order to allow the motor to continue to rotate. The commutator is installed on the motor and equipped with brushes to convert the external DC power into the alternating current in the armature coil, so that the direction of the electromagnetic torque remains constant. [0003] The commutator is a cylindrical component formed by a plurality of commutator segments surrounded by a circular trajectory, and the commutator segments are respectively connected to each tap on the rotor. According to its shape and structure, the commutator can be divided into plane type commutator, slot type commutator, hook type commutator and so on. [0004] In the existing commutator, ...
