Design, Development and Testing of an HTS Pole Coil for 1 kW Superconducting Synchronous Generator

This work presents the comprehensive design, development, and testing of an HTS pole coil for 1 kW, 3 phase, 4 pole, and 120 V partially superconducting synchronous generator employing high-temperature superconducting (HTS) coils in the rotor. The generator is designed to operate in liquid nitrogen. Electromagnetic analysis was carried out to validate the design parameters. An HTS pole coil was fabricated and tested up to its critical current. The development of pole coil demonstrates stable superconducting performance and effective magnetic field generation. The developed prototype demonstrates and establishes the feasibility of integrating HTS pole coil in compact HTS electrical machines for future strategic applications.
