| Outline of Final Research Achievements |
In this study, a flux-modulating synchronous machine (FMSM) for EV/HEV that does not use rare-earth magnets has been developed. Using a small experimental machine, the operating mechanism and characteristics in a motor mode of the FMSM were investigated. In addition to this, a 50-kW FMSM was designed and its characteristics were compared to those of an existing interior permanent magnet synchronous machine (IPMSM). As a result, the FMSM was found to operate only with the magnet torque. Moreover, it was revealed that, in the 50-kW FMSM, the maximum torque of about 90% of the IPMSM can be generated.
