A heat exchange cooling system with 10kW cooling capacity was also developed. The armature is cooled by subcooled LN2 at 65-70 K. The rotating filed is cooled by GHe at around 65 K. As a first step, the 400 kW fully superconducting synchronous motor was pretested by using LN2 at 77 K and three bipolar power supplies. We cofirmed that the installation and connection were done correctly. In near future, we plan to make a full test using a cooling unit and the prepared inverter and conventional synchronous motor. 收起
