AI Technical Summary

Technical Problem

The manufacturing process for stators of axial gap motors is complicated and costly due to the need for integrating a substrate and coil with a molding resin, which requires a dedicated mold and increases the risk of high costs and complexity.

Method used

A method involving a preparation step with first and second substrates and a blocking member, followed by an integration step where molding resin is injected into overlapping holes to integrate the substrates, coils, and blocking member, eliminating the need for a dedicated mold.

Benefits of technology

This method reduces manufacturing costs and ensures strength by integrating the stator components without a dedicated mold, simplifying the process and maintaining structural integrity.

Abstract

To provide a method of manufacturing a stator for an axial gap motor by which cost of manufacture is reduced and a strength is secured, and a stator for an axial gap motor.SOLUTION: A method of manufacturing a stator for an axial gap motor includes: a preparation step of preparing a first substrate including a first hole in which a first coil is disposed, a second substrate which includes a second hole in which a second coil is disposed and overlaps the first substrate in such a manner that the second hole at least partially overlaps the first hole, and a closing member which overlaps the second substrate so as to close the second hole from an opposite side of the first substrate; and an integration step of injecting a mold resin from the side of the first substrate into the first and second holes after implementation of the preparation step, thereby integrating the first and second substrates, the first and second coils and the closing member.SELECTED DRAWING: Figure 6
