Stator iron core making method used for linear motor

The invention discloses a stator iron core making method used for a linear motor. The method comprises the following steps of stepS1, spraying an epoxy resin glue layer on a steel plate surface; stepS2, sending the steel plate in the step S1 into a constant temperature environment for heating; step S3, making the steel plate in the step S2 into a plurality of iron core base materials for forming astator iron core; step S4, stacking and extruding the plurality of iron core base materials; step S5, sending the plurality of iron core base materials in the step S4 into the constant temperature environment for heating; and step S6, placing the iron core base materials after heating in the step S5 in the air, solidifying and acquiring the stator iron core. By using the method of the invention,there is no glue overflow at an edge of the stator iron core, a size of the iron core is not changed, gaps between the iron core base materials are basically the same, mutual conduction between the iron core base materials can
