Description

Technical Field

[0001] The utility model relates to the technical field related to commutators, in particular to a commutator. Background Art

[0002] The commutator, also known as the "rectifier", is an important component on the armature of a DC motor and an AC commutator motor. It is composed of many copper sheets separated by mica sheets and is cylindrical or disc-shaped. Each copper sheet is connected to several armature winding elements. When the armature rotates, the copper sheets contact the fixed brushes one after another. In a DC motor, the AC power in the armature winding is converted into DC power between the brushes through the brushes and the commutator. In an AC commutator motor, the frequency of the AC power between the brushes is made to meet the working requirements.

[0003] The traditional commutator is a hook-type commutator. The longitudinal groove of the hook-type commutator is shallow and the groove is an inward-concave structure. The wear of the carbon brush will cause carbon deposits in the groove, which is difficult to clean, resulting in poor contact or short circuit, thus affecting the normal operation of the motor. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] The technical problem to be solved by the utility model is: since the traditional commutator is a hook-type commutator, the longitudinal groove of the hook-type commutator is shallow, and the groove is an inwardly concave structure, the wear of the carbon brush will cause carbon deposition in the groove, and the cleaning of the carbon deposition is more troublesome, thereby solving the problem of poor contact or circuit breaking, thereby affecting the normal operation of the motor.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a commutator, comprising a commutator segment body, an insulating sleeve, an insulating groove, a wiring groove ring, a welding wire block and a groove, the insulating sleeve being arranged inside the commutator segment body, the insulating groove being arranged on the surface of the commutator segment body, the wiring groove ring being arranged on the outer ring of the commutator segment body, the welding wire block being arranged on the outer ring of the wiring groove ring, and the groove being arranged between the welding wire blocks.

[0008] Furthermore, the insulating groove and the commutator segment body are an integrated structure, and a plurality of the insulating grooves are provided, and the structural specifications of the plurality of insulating grooves are the same.

[0009] Furthermore, the groove is a ladder-shaped structure.

[0010] (III) Beneficial effects

[0011] The utility model provides a commutator with the following beneficial effects: novel structure, the groove adopts a ladder-shaped structure, so that the carbon deposits in the groove can be easily and quickly cleaned, thereby avoiding the phenomenon of poor contact or short circuit, and can ensure the normal operation of the motor.
