Superconducting Cable-Excited Linear Motor Proposed for Long-Stroke Applications
Researchers have proposed a linear motor with superconducting cable excitation as a potential solution for long-stroke and large-capacity linear motor drives . The motor employs an alternately positioned C-shaped and T-shaped core configuration for direct current excitation, offering a more straightforward and stable excitation system structure.
Key Innovations:
Superconducting DC cable low-temperature cooling system: Addresses complex structural design challenges associated with superconducting linear motor low-temperature systems
Alternating C-shaped and T-shaped core configuration: Enables stable DC excitation
Research Findings:
Three-dimensional finite element analysis was used to investigate the impact of secondary structure parameters on motor thrust
Operating environment of the superconducting cable was analyzed
Force on the cable and magnetic field environment were discussed
Relationship between maximum thrust and secondary parameters, cable force during operation, and optimal shield thickness were established
