[Purpose]
In this study, we propose the Cat's Cradle Winding Method for an HTS squirrel-cage winding of induction motor to reduce the number of solder joints.

[Method]
The rotation characteristics of an HTS induction motor that uses the Cat's Cradle Winding were verified by two-dimensional electromagnetic field analysis and experiments using a small prototype.

[Results]
Through electromagnetic field analysis and rotation tests, we have successfully demonstrated high mechanical output with the Cat's Cradle Winding Method.

[Consideration]
Our proposed Cat's Cradle Winding achieves the same or higher mechanical output than conventional squirrel-cage windings, despite requiring far fewer solder joints. Furthermore, the Cat's Cradle Winding may be applicable to superconducting joints.

[Conclusion]
The validity of the Cat's Cradle Winding proposed by us has been analytically and experimentally proven, and is extremely useful in practice.
