Shaftless propulsion technology delivers high efficiency and low noise for subsea installations marine vessels. To enhance thrust performance, the streamlined aft-body contour imposes stringent demands on geometric compatibility between rim-driven thruster (RDT) motor hull. This necessitates advanced electromagnetic characterization of conical motors. paper proposes an equivalent magnetic circuit model (EMCM) that accounts end effects saturation in both stator rotor cores field analysis permanent magnet synchronous (CPMSM). A 3D EMCM is developed by decomposing air-gap flux into radial/axial/tangential components. End-field nonlinearities are addressed via lumped-parameter network modeling. Innovatively, a trapezoidal expanded layout magnet-pole-trimming adopted to ensure sinusoidal distribution. Finally, 10.5 kW prototype with angle 6.7 degrees designed using verified through finite-element (FEA) experiments. research provides theoretical framework rapid CPMSM.
