Abstract

We studied a pulsed field magnetization (PFM) of bulk HTS assembled into a synchronous motor as a field-pole. The PFM is essential to apply bulk HTS inside the machine as a practical technique. In the present study, we developed a PFM technique that is a usage of Controlled Magnetic density Distribution Coil (CMDC). The coil is composed of inner vortex coil and outer solenoid. We successfully obtained the trapped flux density with 1.3 T by the step-wise cooling method with CMDC at 38 K in the motor. The bulk was cooled by a condensed neon. In addition, we studied the PFM for Gd-bulk of 140 mm diameter. By using the CMDC, we obtained the trapped flux density distribution with regular shape. In this paper we report these advanced PFM techniques for a practical machinery applications.
