Abstract
The present disclosure relates to a dual-armature flux-switching electrically excited machine, including a stator and a rotor. The stator includes a stator core, field windings, and stator armature windings. The rotor includes rotor armature windings. When the windings are in a working state, the field windings are fed with a direct current, the stator armature windings and the rotor armature windings are fed with an alternating current, a current phase angle of the stator armature windings can be adjusted between 0° to 90°, and a current phase angle of each of the rotor armature windings can be adjusted between −90° to 0°. Through the dual-armature topology and the cooperation of the current phase angles of the armature windings, the torque density of the electrically excited machine is significantly improved.
