This paper presents drive performance possibilities of brushless synchronous machine with wound-field excitation using SMC core for HEV applications. The proposed machines have no brush or slip ring, rare-earth magnet and employs only wound-field excitation. The structures and the basic working principles for the machine are overviewed. The design target is the motor with maximum power more than 123kW and maximum power density more than 3.5kW/kg. The performance analyses of the designed machines based on 3D-FEA show that the machine meet the target requirements. Finally, some experimental results using a tested down scale machine are demonstrated.
