Several small-scale SC rotating machines have been developed based on HTS bulk materials. Up to now, the role of the SC has been restricted to the rotor where no coil has been required. Despite the difficulty of building classical coils with ceramic materials, we have developed suitable geometries which can be built by machining melt textured YBCO pellets. In this work, we describe a multiphase armature designed to be made starting HTS ceramic pellets. The field created is designed to interact with a disc-shaped rotor producing both the torque and the forces to maintain it in working conditions. Calculations of the field in the rotor cavity generated by the armature in the working conditions are also reported. © 2002 Elsevier Science B.V. All rights reserved.
