The present invention proposes an axial flux reluctance motor with phase-to-phase coupling without a stator yoke, which includes a stator and an axial double-sided rotor. , the stator windings are wound radially around the stator teeth. The rotor adopts block or non-block structure. When the block structure is adopted, the rotor is composed of a U-shaped laminated iron core and a non-magnetic frame, which are evenly distributed on both axial sides of the stator teeth and embedded in the non-magnetic frame; when a non-block structure is adopted , the rotor is composed of a whole permeable core. The motor proposed in the present invention has coupling between two adjacent energized phases, which can not only shorten the length of the motor magnetic flux path, reduce the loss, volume and cost of the motor, but also increase the conduction time of each phase, improve the utilization rate of the winding, and reduce the torque ripple , to increase the power density and torque density of the motor; at the same time, the rotor structure on both sides of the axial direction can also effectively avoid unilateral magnetic pull, reduce operating noise, and improve the stability of motor operation.
