A Starting Method of Ship Electric Propulsion Permanent Magnet Synchronous Motor

AbstractThe propulsion system consisted of the AC - AC Converter and permanent magnet synchronous motor used more often in the current ship electric propulsion. The firstly solving problem is the PMSM starting. In this paper, based on briefly describing the ship electric propulsion system, analyzed the characteristics of the PMSM starting, the system used open-loop frequency starting mode. The analysis shows that the way in ship propulsion PMSM starting running condition, is simple, reliable, good starting performance. The starting mode can also be used as the starting method of a large PMSM for other purposes
