Description

Technical Field

[0001] The present application relates to the technical field of commutators, and in particular to a slot-type 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 in a cylindrical or disc shape. Each copper sheet is connected to several armature winding elements. When the armature rotates, the copper sheets successively contact the fixed brushes. 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 copper sheets of the common commutator are usually solidified together by pouring bakelite powder and mica sheets during installation. However, this fixing method lacks a limiting structure and has poor stability. The copper sheets may accidentally fly out due to the influence of centrifugal force, causing damage to the commutator.

[0013] Through the above solution, the installation pad is provided to improve the insulation of the retaining ring, so as to avoid the retaining ring being affected.

[0014] Furthermore, a plurality of stabilizing grooves distributed in a circumference are provided inside the base body, and the outer surfaces of the plurality of clamping plates are fixedly connected with stabilizing members, and the plurality of stabilizing members are clamped with the stabilizing grooves adjacent thereto.
