Description

Technical Field

[0001] The present invention relates to the technical field of motor processing, and in particular to a device for accurately aligning and placing insulating paper in motor manufacturing. 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. On the stator core of the motor, there are often multiple wire embedding slots and embedded excitation windings to ensure that the motor can work normally. Since the excitation winding is composed of 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, the main method currently used is to insert insulating paper. Motor insulating paper is an insulating material used in motors. Its main function is to prevent unnecessary current flow between different electrical components and ensure the safe and stable operation of the motor.

[0003] The insulating paper is inserted into the wire slot of the motor stator by using a paper insertion device. Since the wire slot has a certain shape structure, the insulating paper needs to be formed first. Generally, the shape of the mold is used to limit the shape of the insulating paper, but this method cannot achieve precise shaping, resulting in poor fit between the insulating paper and the motor stator slot. There is a risk of movement due to vibration or mechanical stress during motor operation, and short circuit or electrical breakdown between components with different potentials inside the motor. For this reason, we propose a precise positioning and placement device for insulating paper in motor manufacturing. Summary of the invention
