Design and analysis of doubly salient permanent magnet dual-mechanical port motor for offshore ships

Yingxing Wang, Yuanyuan Li, Chunxiang Huang


To meet the requirements of the energy power transmission of the hybrid propulsion system, this paper proposes a new type of the doubly salient permanent magnet dual-mechanical port motor. The structure, electromagnetic properties and temperature field analysis are investigated by means of the finite element analysis method. Besides, it studies the output characteristic by establishing a co-simulation model based on the field-circuit coupled method. The simulation results prove that the motor has inherited the advantages of the doubly salient permanent magnet motor, has high reliability and high power density. Meanwhile, the dual-mechanical port can realize the synthesis and distribution of the motor’s energy flow under different operating conditions.
