Description

technical field [0001] The invention relates to the field of commutator technology, in particular to a commutator processing technology. Background technique [0002] The commutator is an important component of the armature of DC motors and AC commutator motors. When the motor rotates, it plays the role of commutation. It is a component used for current commutation on DC motors and AC series motors in order to allow the motor to continue to rotate, commonly known as a commutator. [0003] However, in the process of the existing commutator, most of the stamping dies are used to connect the commutator piece and the bakelite base. Changing the structure and size of the commutator will also reduce product quality, which is not conducive to production and use. Contents of the invention [0004] The object of the present invention is to propose a commutator processing technology in order to solve the shortcomings in the prior art. [0005] In order to achieve the above object...
