Abstract
Permanent magnetization of electric windlass and mooring winch (EWMW) has become a research trend in the development of new generation deck machinery. The paper investigates the development of a low-speed and high-efficiency permanent magnet synchronous motor (PMSM) and its drive system based on the load characteristics and special requirements of an EWMW. Firstly, the design specifications and key points of the motor drive system are analyzed. Secondly, a design method of parameter matching is proposed to design a 110 kW 75 r/min PMSM based on finite element method, field circuit coupling, and co-simulation. Finally, a prototype is developed and applied to a 45 T EWMW. The test results show that the PMSM can attain an efficiency of 94.3% at the rated operation, good traction characteristics with high torque at low speed, and 3 times wide flux-weakening region at constant power. Therefore, the matching design method is effective in the design of PMSM and drive system for EWMW.
