AI Technical Summary

Technical Problem

Existing alignment coil manufacturing methods struggle to maintain the orientation of segment coils when arranging them in an annular shape, leading to difficulties in alignment due to potential tilting and interference.

Method used

The alignment coil manufacturing apparatus employs a jig with radially arranged guides featuring protrusions and adjustable inner and outer diameter guides to align segment coils, ensuring proper orientation and alignment by using guides with protrusions to support the connecting portions of segment coils.

Benefits of technology

This approach effectively suppresses tilting and maintains the orientation of segment coils during alignment, allowing for the efficient assembly of annular alignment coils without significantly increasing manufacturing costs.

Abstract

This method suppresses the tilting of segment coils when aligning multiple segment coils in a circular pattern. [Solution] The aligned coil manufacturing apparatus according to the present disclosure forms an aligned coil by aligning a plurality of segment coils, each having two legs extending parallel to each other and a connecting portion connecting the two legs, in an annular shape. The aligned coil manufacturing apparatus comprises a jig formed by a plurality of guides arranged radially at predetermined angular intervals and having a plurality of slits into which the legs of the segment coils are inserted, the plurality of guides including a first guide and a second guide having a projection that protrudes from the first guide toward the connecting portion of the segment coil into which it is inserted.
