Abstract
The rotating windings of the conventional contra-rotating propulsion machine (CCRPM) bring some bottleneck problems like poor heat dissipation, decreased reliability, and difficult dynamic balance. Therefore, a transverse-dislocated magnetic-field modulated brushless double-rotor machine (TDMFM-BDRM) is proposed. The TDMFM-BDRM operates based on three dimensional (3D) magnetic-field modulated principle, and its stator is not subjected to circumferential force since windings are distributed along the axial direction. Correspondingly, the real-time equal and opposite torques can be generated, which is suitable for contra-rotating propulsion. Moreover, the TDMFM-BDRM employs ring winding with no end winding, which saves a lot of space. The structure, operating principle and characteristics are introduced and analyzed. Then, the 3D air-gap magnetic-field modulated behavior and electromagnetic characteristics are analyzed by FEA. Finally, compared with the structural characteristics and electromagnetic performances of the CCRPM, the TDMFM-BDRM has more robust torque output capability and higher reliability.
