<p>This paper proposes a novel axial flux shaftless rim permanent magnet motor (ASPM) for new energy marine electric propulsion systems. The structure employs a 20-pole, 24-slot configuration, with the main magnetic flux path comprising a mixed magnetic circuit that includes axial, radial, and tangential directions. Helical windings are wrapped around the middle horizontal section of a U-shaped stator core. After power is supplied, the three-phase winding creates a stator magnetic field that rotates continuously in the tangential direction, rather than in a jump-type manner, to reduce torque ripple. The motor features a shaftless structure and is characterized by a high torque at low speeds. This paper describes the structure and operation principles of the motor, performs a three-dimensional finite element analysis of the magnetic field, and compares it with a radially magnetized permanent magnet synchronous motor of the same size. A prototype model was fabricated and its performance was tested.</p>
