Description

Technical Field

[0001] The present invention relates to the technical field of press-in devices, and in particular to a micro commutator press-in device. Background Art

[0002] The commutator, also known as the "rectifier", is an important component on the armature of DC motors and AC commutator motors. 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 successively contact the fixed brushes. In DC motors, the brushes and commutator convert the AC current in the armature winding into DC current between the brushes. In AC commutator motors, the frequency of the AC current between the brushes meets the working requirements.
