Description

[0002] Commutator, also known as "rectifier". An important part of the armature of DC motors and AC commutator motors. Many copper sheets separated by mica sheets form a cylindrical or disc shape, and 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 DC motors, the AC in the armature winding is converted into DC between the brushes through brushes and commutators. In AC commutator motors, the frequency of the AC between the brushes meets the working requirements;

[0003] At present, during the operation of the slot-type commutator, as the speed continues to increase, the segment difference between the commutator segments increases rapidly. Long-term high-speed operation is prone to internal movement, which affects the stability of the motor. Utility Model Content
