Description
This paper focuses on the design of a Vernier machine with HTS bulks on Flux Modulation Pole(FMP) and HTS field winding. Vernier machine gained importance in recent years for low-speed and large- torque (LSLT) applications, such as wind power generation. Despite the Low-speed high-torque capability, Vernier machine have lower Power factor than the power factor of conventional HTS Field Winding synchronous machine. The key of improvement is introduction of HTS bulks which decrease the flux leakage on the Flux Modulation Pole. In the analysis, Finite Element Analysis(FEA) was used to obtain the magnetic flux field distribution and the performance of the Vernier machine which is resulted by the magnetic gearing effect of the FMP. The voltage harmonic components of Vernier machine with HTS bulks was also investigated. Based on the design, we investigate the advantage of the HTS field winding Vernier machine with HTS bulks comparing to the one without HTS bulks.
