Research on Power Supply Strategies of Long Primary Segmented Permanent Magnet Linear Synchronous Motor
long stroke linear motor has an unparalleled advantage in the field of long-distance transport,transfer and electromagnetic launch system; it is also an important development hot-spot in such areas.The paper presents a primary segmented permanent magnet linear synchronous motor (PS-PMLSM),which can solve the problems of the long stroke linear motor in excessive power dissipation,the difficulties of power supply,and inconvenience of manufacturing and maintaining.According to the motor structure characteristics and application background,the paper proposes four feasible strategies--a single inverter series alternating power supply (SISAP),a single inverter parallel alternating power supply (SIPAP),dual inverters alternating power supply (DIAP) and inter-segment optimal power supply (ISOP).Firstly,the article makes studies on those strategies from the economic cost,energy efficiency,the complexity of switching among the segments and the convenience of algorithm application by calculation and simulation.Secondly,the mathematics model of the motor and control system model is deduced from different strategies,respectively.Then,the available control method is derived from the analysis of these models and the motion characteristics.Finally,effects of performance are comparatively analyzed through the simulation.
