| Research Abstract |
In this study, we challenged realization of ultimate torque density of HTSinduction/synchronous machine, in which we have been carrying out pioneering work, by introducing the additional HTS reluctance torque. That is, we installed four pieces of HTS shield body in the rotor core, and then studied their characteristics based on analysis and experiment. We showed the possibility that the studied rotor possesses high efficiency induction/synchronous toque (magnet torque) in steady state. Furthermore、the reluctance torque is added to the above-mentioned magnet torque only at the starting and/or the overload condition, at which higher torque is necessary for adequate traction force.
