Description

Technical Field

[0001] The utility model relates to the technical field of commutator production, in particular to a multi-station commutator automatic pressing machine. Background Art

[0002] The commutator is typically a cylindrical or disc-shaped structure composed of numerous copper plates separated by mica sheets, each of which is connected to certain elements of the armature winding. It is a critical component in the armature of DC and AC commutator motors. The commutator operates through a set of brushes and metal plates (segments). As the motor rotates, the brushes slide along the surface of the commutator segments, contacting only a fixed set of segments at any given moment. By changing which set of brushes contacts the commutator segments, the magnetic field is reversed, allowing the motor to rotate continuously. Commutators are widely used in the automotive industry. For example, electric vehicles and electric bicycles require commutators to convert current. Commutators are also widely used in various DC motors and generators.

[0003] However, in practical use, commutators are key components in motors, electrical appliances, and other devices, used to change the direction of current or switch circuits. Traditionally, commutator production involves manual or semi-automatic pressing, resulting in low production efficiency and high labor costs. Utility Model Content
