Superconducting synchronous motors and generators have the field coil composed of superconductor have the field coil composed of superconductor with almost zero resistance at superconducting state. Therefore, copper loss at the conventional field coil is eliminated and the superconducting machine gets higher efficiency. The armature coil of the superconducting machine is compose of copper wire and supported by non-magnetic material such as FRP (Fiber Reinforced Plastic). Although a fully-superconducting machine with superconducting armature coil has been reserched, it was not developed toward industrial application because of AC transporting loss and difficulty in construction of the cooling structure and so on. This paper contains the design procedure of a 1 MW superconducting synchronous motor using high-tenperature superconductor only for the field coil. Especially, the armature coil is designed by water-cooling in order th dissipate Joule heat easily. Moreover, 3-dimensional electromagnetic design is conducted to get a proper design result and reduce design errors from 2-dimensional approach.
