Description
Technical Field
The utility model relates to the field of commutators, in particular to a copper sheet of a commutator.
Background
Commutators are an important component of dc and ac commutator motor armatures. The main structure is that a plurality of commutator copper sheets are arranged on a commutator support, each commutator copper sheet is connected with a plurality of armature winding elements, and when the armature rotates, the commutator copper sheets are sequentially contacted with a fixed electric brush. In a direct current motor, alternating current in an armature winding is changed into direct current between brushes through brushes and a commutator; in an AC commutator motor, the frequency of AC power between brushes is made to meet the operating requirements.
The commutator copper sheet is an important conductive component in the commutator, and the problem is mainly solved by increasing the thickness of the commutator copper sheet in order to avoid the phenomenon that edges are warped on the left side and the right side of the existing commutator copper sheet, so that the material cost of the commutator copper sheet is increased, the centrifugal force of the commutator copper sheet is increased, and the commutator copper sheet is easily separated from a commutator support.
