Superconducting Multistack Inductor for Synchronous Motors Using the Diamagnetism Property of Bulk Material

An original superconducting synchronous motor topology is presented. The inductor combines both bulk materials and wires to create an alternating magnetic field in the air gap of the motor. A prototype that uses NbTi superconducting wires and YBCO bulks has successfully been designed and constructed...

Description
Summary:An original superconducting synchronous motor topology is presented. The inductor combines both bulk materials and wires to create an alternating magnetic field in the air gap of the motor. A prototype that uses NbTi superconducting wires and YBCO bulks has successfully been designed and constructed. Test results are presented. In the second part of this paper, the possibility of higher power motor is discussed. To do so, the active length needs to be increased. In this paper, a multistack structure is proposed, and computation results show the effectiveness of the suggested approach.
