In order to achieve multi-objective optimization for a permanent magnet water pump motor in heavy commercial vehicles, we propose strategy based on response-surface methodology and the improved sparrow algorithm (CGE-SSA). Firstly, output capacity of during actual operation was tested with an experimental bench determine design parameters motor, then its modeling completed using Ansys Maxwell 2022r2 software. Secondly, model established by taking width, rib slot width as torque (Ta), ripple (Tr), back electromotive force (EMF) amplitude objectives. Meanwhile, three methods—namely, circular sinusoidal chaotic mapping, golden strategy, adaptive weight coefficients—were used improve convergence speed accuracy search (SSA). Finally, synchronous algorithm. A comparative analysis motor’s before after showed that pulsation reverse were significantly optimization.

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.
