Description

Technical Field

[0001] The present application relates to the technical field of motor commutators, and in particular to a motor commutator. Background Art

[0002] The commutator is an important part of the armature of DC motors and AC commutator motors. It is composed of many copper sheets separated by mica sheets, forming 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 DC motors, the AC in the armature winding is converted into DC between the brushes through the brushes and the commutator. In AC commutator motors, the frequency of the AC between the brushes meets the working requirements.

[0003] Most existing commutators are connected to the wires by welding or other bonding methods, which makes it difficult to disassemble them during subsequent maintenance and is very inconvenient when replacing wires of different specifications. Utility Model Content

This arrangement makes it possible to connect the wire and the connecting piece without welding, and when the wire needs to be replaced, the position of the pressure ring can be moved to the other side, driving the limit block to reach the other end of the special-shaped clamping piece to release the clamping of the wire, so that the free clamping of the wire can be achieved, and the connecting wire does not need to be welded, which makes it more convenient to replace the wire, thereby improving the practicality of the device.

At the same time, connecting plates are provided to separate each group of pole pieces to prevent interference between each group of pole pieces during operation, thereby greatly improving the stability of the device operation.

[0016] By adopting the above technical solution and setting the wire opening, the movement of the pressing ring driven by the extrusion rod can be more stable, thereby improving the practicality of the device.

[0017] As a preferred technical solution of the present application, an anti-corrosion oxide layer is sprayed on the outside of the pole piece.

[0018] By adopting the above technical solution, the service life of the pole piece can be effectively prolonged by setting an oxide layer, preventing the pole piece from having problems during operation due to oxidation.
