Abstract: The underwater propulsion motor suffers from low power density due to constraints such as size,voltage,and rotational speed. The introduces a practical multi-objective design method for permanent magnet synchronous motor that integrates Maxwell′s equations with MotorCAD software. The initial design scheme is determined through magnetic circuit analysis calculations,followed by design implementation using Ansoft software and verification through MotorCAD software, ultimately yielding an optimal electromagnetic design for high-power-density underwater propulsion permanent magnet synchronous motor. Experimental results demonstrate remarkable consistency between physical prototypes and simulation
outcomes,effectively resolving endurance challenges in underwater vehicles.
