Description

Technical Field

[0001] The present application relates to the technical field of motor stator processing, and in particular to an insulating paper insertion device for a stator core. Background Art

[0002] A motor refers to an electromagnetic device that realizes electrical energy conversion or transmission based on the law of electromagnetic induction. The motor consists of a rotor and a stator. The stator core of the motor is often provided with multiple wire embedding slots and embedded with excitation windings to ensure that the motor can work normally. Since the excitation winding is composed of conductive wires, in order to avoid conductivity between the excitation winding and the stator core, even if the stator core and the excitation winding are insulated, it is usually necessary to insert insulating paper into the wire embedding slots of the stator core.

[0003] At present, the operation of inserting insulating paper into the stator core is generally done manually, which is time-consuming and labor-intensive. It takes about 20 minutes to insert insulating paper into a single stator core slot. In addition, manual insertion may cause damage or cracking of the insulating paper due to factors such as non-verticality, and the quality cannot be guaranteed. Summary of the invention
