回転子に界磁巻線を備えたハイブリッド界磁モータの基礎検討

抄録

　This paper presents design studies on a hybrid excitation motor (HEM) with a field winding on a rotor. This HEM has a reverse saliency, and in addition to using reluctance torque, it aims to reduce the cost of the inverter by improving the power factor and to eliminate the cost caused by the field winding power supply and slip ring. Using the IPMSM installed in the 3rd generation PRIUS as a comparison target, the efficiency in each operating region was compared by two-dimensional finite element analysis.
