Method for manufacturing stator core for linear motor

Abstract

The invention discloses a method for manufacturing a stator core for a linear motor, comprising the following steps: step S1: spraying an epoxy resin adhesive layer on the surface of a steel plate; step S2: sending the steel plate in step S1 into a constant temperature environment for heating ; Step S3: making the steel plate in step S2 into multiple pieces of iron core base material for forming the stator core; step S4: stacking and extruding multiple pieces of the iron core base material; The multiple iron core substrates in the process are sent to a constant temperature environment for heating; step S6: the iron core substrates heated in step S5 are placed in the air to solidify to obtain a stator core. Using the method of the present invention to make the edge of the stator core will not have glue overflowing, the size of the iron core will not change, the distance between the core base materials is basically the same, and the mutual conduction between the iron core base materials can be prevented, and the magnetic field can be cut independently. Making a linear motor with a core can greatly increase the output value of the motor.

Description

technical field [0001] The invention relates to the technical field of linear motors, in particular to a method for manufacturing a stator core for a linear motor. Background technique [0002] The existing stator cores for linear motors are mostly stacked with multiple iron core base materials, and then the multi-layer iron core base materials are connected and fixed by riveting, resulting in some iron core base materials being closely adhered to each other. As we all know, The stator core of the motor and the rotor cut the magnetic field to generate magnetic induction lines after electrification, and on the stator of the same volume, the core substrates are not close to each other, and the number of core substrates that independently cut the magnetic field is large, which will eventually make the motor More effort. However, it is obviously difficult to make the stator core form the above-mentioned structure by the existing riveting method. Therefore, in the prior art, ep...

AI Technical Summary

Problems solved by technology

The problem caused by this process is that after the glue melts, part of the glue will be squeezed out from the edges of the two adjacent iron core base materials during the hot pressing bonding process, thus affecting the dimensional tolerance of the final iron core teeth

If the tolerance of the teeth of the iron core is too large, it will make it difficult to install the enameled wire coil with the stator core of the original model. The number of enameled wire coils decreases, which affects the output power of the motor
