Simulation and Verification of Dual-Twelve-Phase Permanent Magnet Propulsion Motor Based on SimuNPS Simulation Platform

As the new power system evolves toward a complex structure with high-proportion renewable energy integration and multi-source coordination, its operating conditions grow more diverse and uncertain; motors, as core power equipment, thus face stricter performance and reliability challenges, which raises higher demands for motor simulation accuracy, efficiency, and complex-condition simulation—key goals of Electromagnetic transient simulation. This paper focuses on the Dual twelve-phase permanent magnet propulsion motor, conducting research via SimuNPS (a new power system modeling and simulation software); to explore the motor’s dynamic characteristics under sudden load, it carries out tests to analyze key parameter responses, simulates three scenarios of sudden load addition to rated torque, and collects data on torque, mechanical/electromagnetic angular velocities, and two sets of stator currents. Results show the motor has fast torque response with high control precision, mechanical/electromagnetic angular velocities that recover rapidly after a short drop via electromagnetic regulation, and synchronized stator current steps with high-frequency oscillations, and its fast response and stable output suit high-dynamic scenarios (e.g., ships), providing support for multi-phase motor applications under complex conditions.
