7 DC-Excited Linear Synchronous Motors (DCE-LSM)
Steady State, Design, Transients, and Control
7.1 Introduction and Topologies
DC-excited linear synchronous motors (DCE-LSM) in flat active ac stator (Figure 7.1) configuration [1–3] are favored for MAGLEVs in low, medium, and high-speed active guideway applications because
They provide, by multiple on board dc exciters, suspension control.
They produce, by interaction of dc exciters on board field and ac-fed long primary (stator) active guideways, MAGLEV propulsion.
The propulsion and suspension functions may be decoupled essentially by pure iq vector control in the ac stators fed by inverters placed on ground, along the track, and synchronized with the vehicle motion.
The propulsion efficiency ...
